The x- intercept is 2.

What is intercept?

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

Given:

x + y + z = 2

( x + y + z ) /2 = 1

x/2+ y/2 +z/2 = 1

Intercept of line

x/a + y/b + z/ c= 1

So, comparing

a=2, which is the x- intercept.

Hence, the x- intercept is 2.

Answer:

I'm pretty sure it would be y=4/3x-1.

Step-by-step explanation:

To find a line perpendicular to an already given line, you would switch the sign of the slope. For example if it is already negative, it would flip to be positive and if it were positive, it would flip to be negative. Then you would plug in the new y coordinate at the end so instead of -3 it would be -1. You would also have to do the reciprocal of the slope so you would flip it to be 4/3 instead of 3/4.

Answer:

y = \(\frac{4}{3}\) x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - \(\frac{3}{4}\) x - 3 ← is in slope- intercept form

with slope m = - \(\frac{3}{4}\)

Given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-\frac{3}{4} }\) = \(\frac{4}{3}\)

The line passes through (0, - 1 ) ⇒ c = - 1

y = \(\frac{4}{3}\) - 1 ← equation of perpendicular line

Answer:

The number of regular, large, and extra-large drinks are 12, 15, and 10 respectively.

Step-by-step explanation:

Given that the cost for regular coffee drinks (300 ml)=$2.25

The cost for large coffee drinks (500 ml)=$3.25

The cost for extra large coffee drinks (800 ml)=$5.75

Let p,q, and r be the number of regular, large, and extra-large coffee sold.

As the diner sold a total of 37 coffees, so

p+q+r=37

r=37-p-q...(i)

The volume of p regular coffee = 300p ml

The volume of q  large coffee = 500q ml

The volume of r extra-large coffee = 800r ml

As the total volume of coffee sold was 19,100mi, so

300p+500q+800r=19100

By using equation (i)

300p+500q+800(37-p-q)=19100

300p+500q+800 x 37 - 800p - 800q=19100

-500p-300q=19100-29600

500p+300q=10500

500p=10500-300q

p=21-0.6q...(ii)

Now, the cost of p regular coffee=$2.25p

The cost of q large coffee=$3.25q

The cost of r extra-large coffee=$5.75r

As the amount of money made in coffee sales was $133.25, so

2.25p+3.25q+5.75r=133.25

By using equations (1)  we have

2.25p+3.25q+5.75(37-p-q)=133.25

2.25p+3.25q+212.75-5.75p-5.75q=133.25

3.50p+2.50q=79.5

From equation (ii)

3.5(21-0.6q)+2.50q=79.5

73.5-2.1q+2.5q=79.5

0.4q=79.5-73.5=6

q=6/0.4

q=15

From equation (ii)

p=21-0.6(15)

p=12

From equation (i)

r= 37-12-15

r=10

Hence, the number of regular, large, and extra-large drinks are 12, 15, and 10 respectively.

Answer:

The solution of the equation 4x + 2y = 6 and x − y = 3 will be D. (2, –1)

Step-by-step explanation:

4x + 2y = 6 ....… (1)

x − y = 3 …..... (2)

Example, for equation 2 is:

x - y = 3

x = 3 + y

Put in equation 1:

4(y + 3) + 2y = 6

4y + 12 + 2y = 6

6y = -6

y = -6/6

y = -1

We have the value of y, then the value of x will be:

x = 3 + y

= 3 + (-1)

= 3 - 1

= 2

So, the solution of the equation 4x + 2y = 6 and x − y = 3 will be (2, –1)

Yes, the lengths 6, 8, and 10 form a right triangle.

Use the Pythagorean theorem to see if the given side lengths is of a right triangle. Pythagorean theorem states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, the hypotenuse would be the side with length 10cm, so you can apply the Pythagorean theorem as follows:

(10cm)² = (6cm)² + (8cm)²

100cm² = 36cm² + 64cm²

100cm² = 100cm²

Since the equation holds true, this triangle is a right triangle.

a) Ross's vertical VO2 is 6.42 ml/min/kg.

b) Ross's total relative VO2 is 9.13 ml/min/kg.

To determine Ross's vertical VO2 and total relative VO2, we need to consider the speed and grade of the treadmill.

Given:

Speed = 55 m/min

Grade = 5%

a) Vertical VO2:

Vertical VO2 is the energy expenditure specifically related to vertical displacement.

To calculate it, we need to determine the vertical component of the speed.

Vertical Component of Speed = Speed * Grade/100

Vertical Component of Speed = 55 * 5/100

Vertical Component of Speed = 2.75 m/min

Vertical VO2 = Vertical Component of Speed * 1.8 ml/min/kg

Vertical VO2 = 2.75 * 1.8

Vertical VO2 = 4.95 ml/min/kg (rounded to two decimal places)

b) Total Relative VO2:

Total Relative VO2 includes both the vertical and horizontal components of the energy expenditure. To calculate it, we need to consider the total speed.

\(Total Speed =\sqrt{ (Speed^2 + Vertical Component of Speed^2)}\)

\(Total Speed = \sqrt{(55^2 + 2.75^2)} \\Total Speed = \sqrt{(3025 + 7.5625)} \\Total Speed = \sqrt{(3032.5625)}\)

Total Speed = 55.0726 m/min

Total Relative VO2 = Total Speed * 0.2 ml/min/kg

Total Relative VO2 = 55.0726 * 0.2

Total Relative VO2 = 11.0145 ml/min/kg (rounded to two decimal places)

Therefore, Ross's vertical VO2 is approximately 4.95 ml/min/kg, and his total relative VO2 is approximately 11.01 ml/min/kg.

For shotcrete applications, polymer fibers would be recommended over steel fibers. The reasons why polymer fibers would be preferred are explained below:

1. Compatibility

Polymer fibers are compatible with shotcrete, which is a highly sensitive material that requires additives to be compatible with it. The compatibility of the polymer fibers ensures that they can be mixed with shotcrete and maintain their structural integrity.

2. Corrosion Resistance

One of the most significant advantages of polymer fibers is their corrosion resistance. Concrete structures made with steel fibers are susceptible to corrosion, which can cause structural damage and decrease their lifespan. By using polymer fibers, the structure will be more durable and resistant to environmental conditions that cause corrosion.

3. Ease of Mixing

Polymer fibers are easy to mix into shotcrete, requiring less mixing time and energy. Steel fibers, on the other hand, are challenging to mix and often require specialized equipment, increasing the cost and time required to mix the shotcrete.

4. Durability and Strength

Polymer fibers are stronger than steel fibers and provide better durability. They have high tensile strength, which allows them to withstand external stresses and maintain their shape even under high pressure. Steel fibers, on the other hand, are prone to breakage, reducing the overall strength of the shotcrete.Conclusively, polymer fibers are recommended for shotcrete applications over steel fibers due to their compatibility, corrosion resistance, ease of mixing, and strength.

The possible value of x is 17 and the degree measure of each angle is m∠P = 57°, m∠Q = 110°, and m∠R = 17°.

What are the degree measures of the three angles in triangle?

The angle sum of a triangle will always be equal to 180°. The angle sum of a quadrilateral is equal to 360°, and a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well. Half of 360° is 180°.

We have given,

The triangle PQR,

m∠P=(4x - 9), m∠Q=(6x+2), and m∠R=x. (a) Write an equation to find x.

a)

In a triangle, the sum of the degree measures of the three angles must be 180 degrees.

So for the triangle with angles P, Q, and R, we can use this rule to write the following equation:

m∠P + m∠Q + m∠R = 180

(4x - 9) + (6x + 2) + x = 180

11x - 7 = 180

11x = 187

x = 17

This equation shows that x = 17 is the only possible value of x that satisfies the triangle inequality rule for the given triangle.

b) To find the degree measure of each angle:

m∠P = 4x - 9 = 4(17) - 9 = 57°

m∠Q = 6x + 2 = 6(17) + 2 = 110°

m∠R = x = 17°

Hence, the possible value of x is 17 and the degree measure of each angle is m∠P = 57°, m∠Q = 110°, and m∠R = 17°.

The height to which the hollow sphere rolls up the incline is the same as the height to which the hollow cylinder rolls up, which is 1.0 m in this case.

To determine the height to which the hollow sphere rolls up the incline, we can use the principle of conservation of energy. The initial kinetic energy of both the hollow cylinder and hollow sphere is the same since they have the same mass and initial velocity. This kinetic energy is converted into potential energy as they roll up the incline. The potential energy gained by an object of mass m and height h is given by the formula:

PE = mgh

Since both the hollow cylinder and hollow sphere have the same mass, we can compare their potential energies. Let's assume the potential energy gained by the hollow cylinder is PE_cylinder and the potential energy gained by the hollow sphere is PE_sphere.

PE_cylinder = mgh_cylinder  ... (1)

PE_sphere = mgh_sphere  ... (2)

Since the initial velocity and mass are the same for both objects, we can equate their potential energies:

PE_cylinder = PE_sphere

mgh_cylinder = mgh_sphere

h_cylinder = h_sphere

Therefore, the height to which the hollow sphere rolls up the incline is the same as the height to which the hollow cylinder rolls up, which is 1.0 m in this case.

The value of x is 1. To solve this problem you have to setup the equation like this: 2(2x + 1) = 8x -2. This equation works because since Y is the midpoint, if you double YZ then you get XZ. From the equation you use distributive property to multiply 2 by everything within the parenthesis now the equation should look like this: 4x+2 = 8x -2. Now you can add 2 to both sides making the equation look like this: 4x + 4 = 8x. Then you subtract 4x from each side turning the equation into something like this: 4=4x then you divide by 4 on each side getting your answer: 1 = x.

The value of x if Y is the midpoint of XZ and, XY = 2x - 3 and XZ = 14, is:

x = 5.

Here, we have given that, Y is the midpoint of XZ, it means that the length of XY is equal to the length of YZ.

Given: XY = 2x - 3 and XZ = 14

Since Y is the midpoint, we can set up the equation:

XY = YZ

2x - 3 = XZ - XY

Now, substitute the given values:

2x - 3 = 14 - (2x - 3)

Now, solve for x:

2x - 3 = 14 - 2x + 3

Combine like terms:

2x + 2x = 14 + 3 + 3

4x = 20

Now, divide both sides by 4 to solve for x:

x = 20 / 4

x = 5
