What is the x-intercept of the equation y=-5x+1,450?

x = 290

Step-by-step explanation:

The x- intercept is the point on the x- axis where the line crosses.

substitute y = 0 into the equation and solve for x

- 5x + 1450 = 0 ( subtract 1450 from both sides )

- 5x = - 1450 ( divide both sides by - 5 )

x = 290 ← x- intercept

line crosses x- axis at (290, 0)

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
