Answer:

John and Mike are correct, Henry is incorrect.

Step-by-step explanation:

Try to find x = 4 for all the equations to find out who is correct.

John:

4x + 4 + 7x = 48

Combine like terms.

11x + 4 = 48

Subtract 4 from both sides.

11x = 44

Divide both sides by 11.

x = 4

John is correct.

Mike:

2x + 3 = 11

Subtract 3 from both sides.

2x = 8

Divide both sides by 2.

x = 4

Mike is correct.

Henry:

8x + 7 = 71

Subtract 7 from both sides.

8x = 64

Divide both sides by 8.

x = 8

Henry is incorrect.

Find the coordinates of the y-intercept and x-intercepts of the following. (image!)
marissa [1.9K]

Answer:

Step-by-step explanation:

We can do this  a couple of ways. We can graph it -- see below. Or we can do the math.

Math

y = x^2 - 2x - 15

This trinomial factors into

y = (x - 5)(x + 3)

from which

x - 5= 0

x = 5

and

x + 3 = 0

x = - 3

The y intercept is the value obtained when all the xs on the right = 0

y = 0^2 - 2*0 - 15

y = - 15

<em>Answer</em>

  • x intercepts: (-3,0),(5,0)
  • y intercept: (0,-15)

The graph is below.
