First you do 3.5z-2.7z= .8z then you divide .8 with -6, which gives you -7.5 so z= -7.5
Answer:
C
Step-by-step explanation:
The red graph is the graph of y = f(x) shifted 1 unit right and then reflected in the x- axis.
Given y = f(x) then f(x + a) is a horizontal translation of a units
• If a > 0 then shift to the left of a units
• If a < 0 then shift to the right of a units
Here shift to the right of 1 unit, thus
y = f(x - 1)
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
Note the y- coordinates are the negative of each other, thus
- y = f(x)
Now
= - y, hence
The equation for the red graph is
= f(x - 1) → C
I got 2 but this could be wrong. Hope this helps ;D
I recommend that you download photomath, it is an app that takes a photo of the equation and answers it most of the time.
