Evaluate the equation the you in the picture up above.

evaluate f(x) =

f(x) = -2x² + 4       Find f(4) --->  x = 4, so you need to substitute the number in for x in the function

f(x) = -2x² + 4  

f(4) = -2(4)² + 4       Square 4

f(4) = -2(16) + 4     Multiply -2 and 16

f(4) = -32 + 4     Simplify

f(4) = -28

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
