Answer:

n = -19

Step-by-step explanation:

10n - 7 = -(-9n) - 26

Move all like terms to one side of the equation or the other.

-7 + 26 = -(-9n) - 10n

Combine all like terms.

19 = -(-9n) - 10n

Two minus signs = a positive

19 = 9n - 10

19 = -n

Divide by -1

-19 = n

Answer:c=1

Step-by-step explanation:Step 1: Simplify both sides of the equation.

−5=−3(c−2)−8

−5=(−3)(c)+(−3)(−2)+−8(Distribute)

−5=−3c+6+−8

−5=(−3c)+(6+−8)(Combine Like Terms)

−5=−3c+−2

−5=−3c−2

Step 2: Flip the equation.

−3c−2=−5

Step 3: Add 2 to both sides.

−3c−2+2=−5+2

−3c=−3

Step 4: Divide both sides by -3.

−3c

−3

=

−3

Answer:

The jalapeno poppers cost: $8.87

Step-by-step explanation:

Step 1: How much did all friend pay total: $8.94 * 3 friends = $26.82

Step 2: How much were the jalapeno poppers? We need to subtract the nacho cost from the total paid by the friends: $26.82 - $17.95 = $26.82 = $8.87

Answer:

A

Step-by-step explanation:

Because 1 has more than one output, first they are putting 1 and 1 together, next they are putting it with 2, 1 has more than one output.

8 liters

We know that 1000 mL = 1 liter

8 liters * 1000ml / 1 liter = 8000 ML

That is more than 800 mL

Answer:

2

Step-by-step explanation:

There are four giraffes that equal 32. That means the four of them equal 32, and since they are all giraffes, they are the same amount.

32/4 = 8

Girrafe = 8

Two tigers times a giraffe equals 32. We already know that a girrafe equals 8.

32/8 = 4.

Therefore the two tigers equal 4. Since there are two tigers, and they equal 4, each tiger equals 2.

Now we know girrafes equal 8, and tigers equal 2.

A girrafe - A tiger x 3 = 2

PEMDAS says that you multiply first. So 2 x 3 equals 6. Take away 6 from 8 and you get 2.

Answer:

1) -13

2) 36

3) -2

4) -5

5) -6

6) -216

Step-by-step explanation:

The output for the considered rules are: Rule 1: -13, Rule 2: 36, Rule 3: -2, Rule 4: -2, Rule 5: π, Rule 6: 216 cubic cm.

Function is a type of relation, or rule, that maps one input to specific single output.

We're given that:

Applying all the rules, one by one:

Rule 1: Subtract -7

\(\rm \text{inp}ut -7 = -6 -7 = -13\)

\(\rm (\text{inp}ut )^2 = (-6)^2 = -6\times -6 = 36\)

\(\rm \dfrac{\text{inp}ut }{3} = \dfrac{-6}{3} = -2\)

Dividing something in x parts means that thing divided by x

\(\rm \dfrac{\text{inp}ut }{3} = \dfrac{-6}{3} = -2\)

\(\pi\)  (no use of input).These type of functions which always give same constant result, no matter what the input is, are called constant functions.

Volume of a cube is the cube of its side length (raising it with power 3).

We're specified that:

Side length of the considered cube = input = -6 cm

Since length is a non-negative quantity, so we take absolute value of -6, therefore, we have:

side length of the cube = |-6| = 6 cm

Thus, its volume is:

\(V= (\rm side)^3 = 6^3 = 216 \: \rm cm^3\)

Thus, the output for the considered rules are: Rule 1: -13, Rule 2: 36, Rule 3: -2, Rule 4: -2, Rule 5: π, Rule 6: 216 cubic cm.

Answer: We can find the equation of a plane in point-normal form, which is given by:

Ax + By + Cz + D = 0

where (A, B, C) is the normal vector to the plane and (x, y, z) are the coordinates of any point on the plane, and D is a constant.

To find the normal vector, we can use the cross product of two vectors that lie on the plane. A convenient choice for these vectors is the direction vector of the line, which is given by:

v = <2-3, -1-4, 5-(-1)> = < -1, -5, 6 >

The normal vector to the plane is given by the cross product of the direction vector of the line and the vector pointing from any point on the line to the point (2,-3,1). Let's call this vector v2 = <2-3, -3-4, 1-(-1)> = < -1, -7, 2>

So the normal vector is given by:

n = v x v2 = ( -52 + 6-7)i + (6*-1 - -12)j + (-1-7 - -5*2)k = (14)i + (-7)j + (-11)k

Given that the point (2,-3,1) lies on the plane, we can substitute these values in the point-normal form equation:

A2 + B-3 + C*1 + D = 0

-142 + -7-3 + -11*1 + D = 0

-28 - 21 - 11 + D = 0

D = 58

So the equation of the plane is :

14x - 7y - 11z + 58 = 0

This is the equation that represents the plane that passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5)

Input Equation:

(100+650)-(2/300) = (750)-(2/300)

= 750 - (0.0066666666666667)

Answer:

C. 6.9 miles

Step-by-step explanation:

Use Pythagoras theorem!

a^2 = b^2 + c^2 where a is the hypothenuse

rearrange to find x

a^2 - b^2 = c^2

so 8^2 - 4^2 = x^2

64 - 14 = 48

√48 = 6.9 miles :)

Answer:

C

Step-by-step explanation:

Answer:

Part A: 8

Part B: $1

Step-by-step explanation:

We know that 3 bushels is $24, and that rate remains constant, as the graph has a straight line.

Divide both sides by 3 to get 1 bushel = $8.

We can also double check with the other values: 48/6=$8 per bushel, 72/9=$8 per bushel, and so on.

The rate of change is the slope of a line (how much one value changes when the other value does). In this equation, the equation of the line is y=8x, so the slope is 8. Therefore, the rate of change is 8.

In the previous year, each bushel of corn was 21/3, 42/6, etc., or $7 a bushel. This year, it is $8, so $8-$7=$1

Therefore, the price has increased by $1 this year.

Answe

Step-by-step explanation:  Part A:

a

For this problem, I would find the rate of change by finding the slope, which is the change in y over the change of x(y2-y1/x2-x1). In this case, for the current year, it would be 24(48-24) (change in y's) divided 3 (6-3)(change in x's), which comes out to 6. Hence, the rate of change for the current year is 6.

Part B:

Using the same method, the rate of change for the previous year would be 7. I found it by using the same equation. It would (42-21=21)(change in y's) / (6-3=3)(change in x's). 21/3 =7. Hence, for the previous year, the rate of change is 7.So the difference between the previous and current year is $1 (7-6).

Answer:

$45.75

Step-by-step explanation:

1. Set up the equation: 40.75 + 2.25 - 1.75 - 0.25 + 3 + 1.75 = x

You want to include the amount that she started with which is $40.75 . In this case x is the total amount of money that Samantha has by the end of the week. If Samantha loses money on a certain day you will subtract it, whereas if she gains money you will add it.

2.Simplify: 43 - 1.75 - 0.25 + 3 + 1.75 = x

I just added the 1st two numbers. You can just type this into the calculator if you are comfortable with that or you can solve this by adding and subtracting the numbers on a piece of scratch paper.

3. Simplify: 41.25 - 0.25 + 3 + 1.75 = x

4. Simplify: 41 + 3 + 1.75 = x

5. Simplify: 44 + 1.75 = x

6. Simplify: 45.75 = x

The answer to part A is: 944,697,600 km3.

The answer to part B is: 39,362,400 km3.
