Use the zero product property to find the solutions to the equation x2 + 12 = 7x.
x = -4 or x = 3
x = -4 or x = -3
Ox=-3 or x = 4
x = 3 or x = 4

x = 3, x = 4

Step-by-step explanation:

Given

x² + 12 = 7x ( subtract 7x from both sides )

x² - 7x + 12 = 0 ← in standard form

(x - 3)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 4 = 0 ⇒ x = 4

Step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

it is 10.6 according to my calculations
