Hailey and her children went into a grocery store and she bought $10 worth of apples

and bananas. Each apple costs $1.25 and each banana costs $0,50. She bought a total

of 14 apples and bananas altogether. By following the steps below, determine the

number of apples, 2, and the number of bananas, y, that Hailey bought

Determine three ways to Have a total of 14 apples and bananas:

Cost of apples: $0.00

Cost of bananas: 50.00

### Answers

**Answer:**

a = 4

b = 10

**Step-by-step explanation:**

Price of an apple $1.25

Price of a banana $0.50

The two equations:

10 = 1.25a + 0.5b

a + b = 14

solve for one variable

b = 14 - a

10 = 1.25a + 0.5(14-a)

10 = 1.25a+ 7 - 0.5a

10 = 0.75a + 7

0.75a = 3

a = 4

Then solve for the second

b = 14 - 4

b = 10

find the equation of the line.

1 10

3 24

6 45

11 80

15 108

from 10 to 24 you add 14

from 1 to 3 you add 2

so y/x

14/ 2 = 7

check:

from 24 to 45 you add 21

from 3 to 6 you add 3

so y/x

21/3 = 7

From y/x your final answer will always be 7.

So the rate of change will be 7.

Write and equation in slope-intercept form of the line with slope -1/2 that contains the point (-4,-3)

### Answers

**Answer:**

y=-1/2x-5

**Step-by-step explanation:**

Well we know that the slope is -1/2 so we can write the equation like this:

y=-1/2x+b (This is because of y=mx+b) (m is slope) (b is y-intercept)

Now we can replace the y and x with -4 and -3 because of (x,y). (-4,-3) x is -4 and y is -3

-3=-1/2(-4)+b

-3=2+b

Subtract 2 on both side:

-2-3=2-2+b

-5=b

Answer:

y=-1/2x-5

**Step-by-step explanation:**

Step 1: Define equation

4 - 3p = 22

Step 2: Solve for *p*

Subtract 4 on both sides: -3p = 18Divide -3 on both sides: p = -6

Step 3: Check

*Plug in p into the original equation to verify it's a solution.*

Substitute in *p*: 4 - 3(-6) = 22Multiply: 4 + 18 = 22Add: 22 = 22

Here we see that 22 does indeed equal 22.

∴ p = -6 is a solution to the equation.

The volume of a cylinder of height 8 cm is 72π cm3 Find the radius of the cylinder.

### Answers

**Answer:**

3 cm

**Step-by-step explanation:**

Divide the volume by the height

72π/8 = 9π

Now we have the surface area. The surface area is π[tex]r^{2}[/tex], so we reverse it.

Divide the number by π:

9π/π=9

Now we find the square root

3 x 3 is 9, so 3 is the square root and radius.
