Which ordered pair does NOT lie on the graph of h(x )= -2x + 7I have no idea how to solve this, please help me! Thanks!

Answers

Answer 1

Answer:

Replace X with the x value in the parenthesis and solve. If the answer equals the Y value inside the parenthesis, it is a solution.

A) (-2, 3), -2(-2) +7 = 4+7 = 11. 11 does not equal 3 so this is not a solution.

B) (-1,9), -2(-1) +7 = 2+7 = 9. 9 equals 9, this is a solution.

c) (3,1), -2(3)+7 = -6+7 = 1, 1 equals 1, this is a solution.

d) (4,-1) = -2(4) +7 = -8 +7 = -1. -1 equals -1, so this is a solution.

The only one that isn't a solution is A.

Jorge plans to paint a bedroom wall that is shaped like a trapezoid. The bottom edge of the wall is 22.5 feet long, and the top edge of the wall is 9.5 feet long. If the wall is 8 feet tall, what is the area of the wall?

Answers

Length of the bottom edge of the wall (a) = 22.5 feet
Length of the top edge of the wall (b) = 9.5 feet
Height of the wall (h) = 8 feet
Then
Area of the wall = [(a + b)/2] * h
      = [ (22.5 + 9.5)/2] * 8 square feet
   = (32/2) * 8 square feet
   = 16 * 8 square feet
   = 128 square feet
As can be seen from the above deduction, the area of the wall is 128 square feet. I hope the procedure is not complicated for you to understand. You can normally use this method in future for solving similar type of problems without requiring any additional help.

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(x) − 4?

Answers

Answer:

F(x) -4 shifts it down 4 units from f(x)

Step-by-step explanation:

When we add or subtract from f(x) this causes a shift in the vertical direction.

When we add it shifts it up.

When we subtract is shifts it down
