need to solve for x
4x - 2 = 2x + 1

The value of x from the equation is 1

The value of y from the equation is 7

-5x+2y= 9............equation 1

y= 7x...............equation 2

Substitute 7x for y in equation 1

-5x + 2(7x) = 9

-5x + 14x= 9

9x= 9

x= 9/9

x= 1

Substitute 1 for x in equation 2

y= 7x

Answer:

B

Step-by-step explanation:

SSS stand for Side Side Side, so the truangle must identify all it's sides. To identify sides it uses lines through the side like in B where 1 side has 1 line, 1 side has 2 lines, and the other side has 3 lines. That is the side identifiers, and because each side in B matches with 1 side in A, means that A and B are congruent because they have the same sides, so SSS.

A graph of the solution to this inequality on the number line is shown in the image attached below.

In Mathematics, an inequality simply refers to a mathematical relation that is typically used for comparing two or more numerical values and variables in an algebraic equation based on any of the following inequality symbols:

In this exercise, we would solve the given inequality by making x the subject of formula as follows;

-x/4 + 2/3 ≤ -1/2

By subtracting 2/3 from both sides of the inequality, we have the following:

-x/4 + 2/3 - 2/3 ≤ -1/2 - 2/3

-x/4 ≤ -1/2 - 2/3

x ≥ 14/3.

In triangle ABC, a perpendicular bisector AD is drawn on BC. We can see that triangle ABD and triangle ACD are right-angled triangles. The missing side x is 9√3/4.

A triangle is a three-sided polygon with three angles. The sum of the interior angles of a triangle is always 180 degrees. Triangles can be classified in several ways based on their sides and angles.

There are also several important properties of triangles, such as the Pythagorean theorem which states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (the hypotenuse). Triangles also have several geometric formulas associated with them, such as the area formula (1/2 * base * height) and the perimeter formula (sum of all sides). Triangles are an important concept in geometry and have many practical applications in fields such as engineering and physics.

In triangle ABC, a perpendicular bisector AD is drawn on BC. We can see that triangle ABD and triangle ACD are right-angled triangles.

Using trigonometry, we can write the following equations:

sin(60) = BD/AB (Using triangle ABD)

cos(60) = CD/AC (Using triangle ACD)

We know that AB = x and CD = 3. We need to find x.

Rearranging the first equation, we get:

BD = AB * sin(60)

Substituting the value of BD in the second equation, we get:

cos(60) = CD/AC

cos(60) = 3/2BD

cos(60) = 3/2(AB * sin(60))

cos(60) = 3/2(x * √3/2)

cos(60) = 3√3/4x

Multiplying both sides by 4x/3√3, we get:

4x/3√3 * cos(60) = 3

Simplifying, we get:

x = 9√3/4

Therefore, the missing side x is 9√3/4.

Answer:

The required number is 7

Step-by-step explanation:

Let a number = x

We are given the condition: five more than three times a number is 26

We need to find the number.

Writing the condition in mathematical form:

five more than three times a number is 26: \(3x+5=26\)

Now, solving this equation we can find x, the number

\(3x+5=26\\\)

Subtract 5 from both sides

\(3x+5-5=26-5\\3x=21\)

Divide both sides by 3

\(\frac{3x}{3}=\frac{21}{3}\\x=7\)

So, we get: x = 7

The four capital letters of the alphabet in block style with 180-degree rotational symmetry are H, I, O, and X

The four capital letters of the alphabet that have rotational symmetry of 180 degrees and can be written in block style are H, I, O, and X. These letters have a vertical and horizontal line of symmetry that divides them into two identical halves, and when rotated 180 degrees, they appear exactly the same as their original orientation.

The letter H has two vertical lines that bisect it horizontally, creating four identical quadrants. The letter I has a vertical line of symmetry running through the center, creating two identical halves. The letter O has a circular shape that is symmetric around its center, and the letter X has two diagonal lines of symmetry that intersect at its center, creating four identical quadrants.

Oa

9 granola bars. each friend gets 1/2 bar.

when we break 1 bar in half, we get 2 halves.

now we break 9 bars in half, so we do this 9 times.

that means we get 9×2 = 18 halves.

so, 18 friends get half a bar.

there would be an equation like

9 / 1/2 = 18

Ob

9 pizzas. I assume each pizza has 8 slices.

so, we have 9×8 = 72 slices.

now we put out of these 72 slices 2 slices per plate.

so, we need 72/2 = 36 plates.

please adapt the calculation and replace 8 by the actual number of slices, if I misunderstood.

the equation here would be something like

9×8/2 = 36

Oc

1/2 box of Britain's is distributed equally to 9 people.

that means we need to divide 1/2 by 9.

1/2 / 9 = 1/2 / 9/1 = 1/2 × 1/9 = 1/18.

remember, when dividing by a fraction it is the same as multiplying with the upside-down fraction.

so, each family member gets 1/18 of the box.

the equation here would be something like above

1/2 / 9 = 1/18

Answer: 18/9 if not it's something along that-

Step-by-step explanation:

7^2 = 49 so like 49-31 equals 18 and the denominator 3^2 = 9 , so if it's not 18/9 then it's like 1/2 or something bc 9 + 9 is 18 yk-

5[cos (340°) + i sin (340°)]* 6 [ cos (253) + i sin (253)]  in trigonometric form is 30[cos(233°) + i sin(233°)] .

5[cos(340°) + i sin(340°)] * 6[cos(253°) + i sin(253°)]

Using the properties of complex numbers and trigonometric identities, we can simplify this expression

= 5 × 6 [cos(340° + 253°) + i sin(340° + 253°)]

= 30 [cos(593°) + i sin(593°)]

Since 0° < θ < 360°, we can express 593° as 593° - 360° = 233°:

= 30 [cos(233°) + i sin(233°)]

Therefore, the result of the operation is 30[cos(233°) + i sin(233°)] in trigonometric form.

Without the standard deviation, we cannot calculate the standard error or the 95 percent confidence interval for the mean time required to stabilize emergency condition 4 using display panel B.

To calculate a 95 percent confidence interval for the mean time required to stabilize emergency condition 4 using display panel B, we can use the least squares means estimates provided in the JMP output.

According to the JMP output, the estimate for the mean time required to stabilize emergency condition 4 using display panel B is 10.375000.

To calculate the confidence interval, we need to find the margin of error. The margin of error can be calculated using the formula:

Margin of Error = Critical Value * Standard Error

In this case, we need to find the critical value for a 95 percent confidence interval. Since we have a sample size of 24 (as mentioned in the question), we can use the t-distribution with (24-1) degrees of freedom to find the critical value.

Looking up the critical value in the t-distribution table, with (24-1) degrees of freedom and a confidence level of 95 percent, we find that the critical value is approximately 2.064.

The standard error can be calculated using the formula:

Standard Error = Standard Deviation / √(sample size)

The standard deviation is not provided in the given information. Therefore, we cannot calculate the standard error or the confidence interval without this information.

In summary, without the standard deviation, we cannot calculate the standard error or the 95 percent confidence interval for the mean time required to stabilize emergency condition 4 using display panel B.

The slope of the tangent to the curve x² + y³ = 12 at the point when x = 2 is

To find the slope of the tangent to the curve x² + y³ = 12 at the point when x = 2, we need to find the derivative of y with respect to x using implicit differentiation.

Taking the derivative of both sides with respect to x, we get: 2x + 3y²(dy/dx) = 0

We want to find the slope when x = 2, so we substitute x = 2 into the equation above: 2(2) + 3y²(dy/dx) = 0 4 + 3y²(dy/dx) = 0 3y²(dy/dx) = -4 dy/dx = -4/(3y²)

Now, we need to find the value of y when x = 2. Substituting x = 2 into the original equation, we get: 2² + y³ = 12 y³ = 8 y = 2 So, when x = 2, y = 2. Substituting this into the equation for dy/dx, we get: dy/dx = -4/(3(2²)) = -4/12 = -1/3
