Write the english sentence as an equation in two variables. then graph the equation.

the y-value is eight decreased by the square of the x-value.

the sentence can be translated to the equation ?

use the graphing tool to graph the equation.

  y = 8 - x^2

Step-by-step explanation:

"Decreased by ..." means whatever follows is subtracted from whatever came before. "Is" means "equals." So, the square of the x-value (x^2) is subtracted from 8:

  y = 8 - x^2

a

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
