Answer:

B

Step-by-step explanation:

From -1 to 1 on the x-axis, the graph has to be below the x-axis because then the y-values will be negative.

Answer choice C & D have the graph above the x-axis in that interval, so it's positive instead of being negative. We can cross out those two answer choices.

The reason why answer choice A isn't correct is because at 1, the graph line is above the x-axis, since the brackets [-1, 1] means it includes -1 and 1.

So the only answer left is B.

Hope that helps (●'◡'●)

What is the value of z?
babymother [125]

Answer:

Step-by-step explanation:

<u>Item 1:</u>

Discount = Original price - discount price

             = 22.50 - 13.50

             = $ 9

Discount percentage = \frac{9}{22.50}*100\\\\

                                   = 40%

Discount percentage = 40%

Tax = 14.31 - 13.50 = $0.81

Tax% = \frac{0.81}{13.50}*100\\\\  = 6%

Tax percentage = 6%

<u>Item 2:</u>

Tax = 6% of 16.20

      = 0.06 * 16.20

      = 0.972

Tax = $ 0.97

Total price (including tax )= 16.20 + 0.97 = $ 17.17

         x = $ 17.17

<u>Item 3:</u>

Discount  = 40% of 32.50

                        = 0.4 * 32.50

                        = $ 13

y =  32.50 -13

y = $ 19. 50

Tax = 6% of 19.50

       = 0.06 * 19.50

       = 1.17

z = 1.17 + 19.50

Z  =$ 20.67

Well if my math is correct, x= -7, meaning 4x-4= (4*-7)-4. That equals -32.
