The answer would be 11 because the x's 9 doesnt have to move because they're on the same point. If you take 7 away from -7 you get zero. Add 4 to that 7 and you get 11. Make sesnse?
Hope this helped!

What is the perimeter (please explain your answer)
Alex

Answer:

<em>Answer: B. 38 mm</em>

Step-by-step explanation:

<u>The Perimeter of a Shape</u>

The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.

The figure shows a shape where all the external measures are given except the leftmost side.

This length is the sum of 3 mm + 10 mm = 13 mm.

Now calculate the perimeter:

P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm

Answer: B. 38 mm

Which graph represents the function?
Setler79 [48]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

1) f(x)=(x+2)^2 -----> For the interval (-∞,-1)

Note The value of x=-1 is a open circle ( is not included)

This is a vertical parabola open upward

The vertex is a minimum

The vertex is the point (-2,0)

2) f\left(x\right)=\left|x\right|+1 ----> For the interval [-1,1]

Note The value of x=-1 and x=1 are closed circle ( both values are included)

This is an absolute function open upward

The vertex  is the point (0,1)

3) f(x)=-\sqrt{x} -----> For the interval (1,∞)

Note The value of x=1 is a open circle ( is not included)

The value of f(x) is negative for all values of x

therefore

The graph in the attached figure

Which of the following is the maximum value of the function y = -x2 + 2x + 1?
Romashka-Z-Leto [24]

We first complete the square.

y=-x^2+2x+1

y=-x^2+2x-1+1+1

y=-(x-1)^2+2

The maximum point is (1,2) since -1 in ( ) meant 1 unit to the right and +2 meant 2 units up.

The maximum point is (1,2) but the maximum value means the y value which is simply just 2.

Done!
