Which is the x-value of the solution of the system of equations? y=3x^2+15 y=5x^2-17

Readme [11.4K]

Answer:

C. x = ±4

Explanation:

<u>Given two equation's</u>:

y = 3x² + 15
y = 5x² - 17

Solve them simultaneously:

y = y

3x² + 15 = 5x² - 17

5x² - 3x² = 15 + 17

2x² = 32

x² = 16

x = ±√16

x = ±4

For their craft project during the first week of camp, the campers used clothespins to make miniature rocking chairs. To make 90

fenix001 [56]

1080 clothespins makes 90 chairs and we need to find out how many clothespins it takes to make 1 chair.

We can set up a proportion of the number of chairs to the number of clothespins because of the proportional relationship.

x is the number of clothes pins for 1 chair

$\frac{90 chairs}{1080 clothespins} =\frac{1 chair}{x clothespins}$

Cross multiply to get

90*x= 1080*1

Divide both sides by 90 to isolate x

x = 12 clothespins

It takes 12 clothespins to make 1 chair.
