Which of the following is a true statement about the equation y = -7/8x + 10
Greeley [361]

Answer:

Step-by-step explanation:

y = -7/8x - 10

in y = mx + b form, which is what this is in, the slope can be found in the m position

y = mx + b

y = -7/8x - 10

so u have slope (m) = - 7/8 <====

the slope is not 10

the graph will not pass thru the origin

this equation does not represent a proportional relationship

(x2 + 4)(x2 - 4) please help
VikaD [51]

(x^{2} + 4)(x^{2} - 4)

To solve this question you must FOIL (First, Outside, Inside, Last) like so

First:

(x^2 + 4)(x^2 - 4)

x^2 * x^2

x^4

Outside:

(x^2 + 4)(x^2 - 4)

x^2 * -4

-4x^2

Inside:

(x^2 + 4)(x^2 - 4)

4 * x^2

4x^2

Last:

(x^2 + 4)(x^2 - 4)

4 * -4

-16

Now combine all the products of the FOIL together like so...

x^4 - 4x^2 +4x^2 - 16

Combine like terms:

x^4 - 4x^2 +4x^2 - 16

- 4x^2 +4x^2 = 0

x^4 - 16 <<<This is your answer

Hope this helped!
