Answer:

a, b & d

Step-by-step explanation:

y - 10 = 2x

Divide by 2

½y - 5 = x

½y = x + 5

Basically both equations represent the same line, so infinite solutions

(0,10) is a solution

10 - 10 = 2(0)

0 = 0

(1,12) is a solution

12 - 10 = 2(1)

2 =

(2,-6) is not a solution

-6 - 10 = 2(2)

-16 = 4

(-5,0) is a solution

0 - 10 = 2(-5)

-10 = -10

Answer:

A, B, and D

Step-by-step explanation:

Let's put all the answer choices in for x and y in both equations:

A) x = 0, y = 10

10 - 10 = 2 * 0 --> 0 = 0, which works

1/2 * 10 = 0 + 5 --> 5 = 5, which works

So, A is correct

B) x = 1, y = 12

12 - 10 = 2 * 1 --> 2 = 2 which works

1/2 * 12 = 1 + 5 --> 6 = 6, which works

So, B is correct

C) x = 2, y = -6

-6 - 10 = 2 * 2 --> -16 = 4, which doesn't work

So, C is incorrect

D) x = -5, y = 0

0 - 10 = 2 * -5 --> -10 = -10, which works

1/2 * 0 = -5 + 5 --> 0 = 0, which works

So, D is correct

Thus, the answers are A, B, and D.

Hope this helps!

Jesse sold cupcakes and cookies yesterday. Each cupcake sold for $1.50 and each cookie sold for $0.25. At the end of the day, Je
ale4655 [162]

Answer: 19 cupcakes and 37 cookies were sold.

Step-by-step explanation:

Let x represent the number of cupcakes that Jesse sold yesterday.

Let y represent the number of cookies that Jesse sold yesterday.

If he sold 56 cupcakes and cookies combined, it means that

x + y = 56

Each cupcake sold for $1.50 and each cookie sold for $0.25. At the end of the day, Jesse had sold $37.75 worth of cookies and cupcakes. This means that

1.5x + 0.25y = 37.75 - - - - - - - - - - -1

Substituting x = 56 - y into equation 1, it becomes

1.5(56 - y) + 0.25y = 37.75

84 - 1.5y + 0.25y = 37.75

- 1.5y + 0.25y = 37.75 - 84

- 1.25y = - 46.25

y = - 46.25/ - 1.25

y = 37

x = 56 - y = 56 - 37

x = 19

suppose the line segment whose endpoints are H(5,0) and I(-6,-3) is reflected over the y axis? what are the coordinates of H’I’?
padilas [110]

Answer:

see explanation

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ), thus

H(5, 0 ) → H'(- 5, 0 )

I(- 6, - 3 ) → I'(6, - 3 )
