Answer:x=-7

Step-by-step explanation:

Regroup terms.

8x-2=7x-98x−2=7x−9

2 Subtract 7x7x from both sides.

8x-2-7x=-98x−2−7x=−9

3 Simplify  8x-2-7x8x−2−7x  to  x-2x−2.

x-2=-9x−2=−9

4 Add 22 to both sides.

x=-9+2x=−9+2

5 Simplify  -9+2−9+2  to  -7−7.

x=-7x=−7

Answer:

x = - 7

Step-by-step explanation:

8x - 2 = -9 + 7x   (add 2 to both sides)

8x - 2 + 2 = -9 + 7x + 2

8x = 7x - 7           (subtract 7x from  both sides)

8x - 7x = 7x - 7 - 7x

x = - 7

What are the zeros of the graphed function?
Zanzabum

Answer:

Option C

Step-by-step explanation:

Zeros of a function are also called as x-intercepts of a function, which means where the graph/function intersects the x-axis.

In the image we see the graph intersects the x-axis at three points

x=0 , x=2 , x=4 so our answer is option C

What was the equation of the graph below before it was shifted to the right 1.5 units?
Ira Lisetskai [31]

Answer:

 B is correct.

{tex]G(x)=x^3-x[/tex]

Step-by-step explanation:

We are given a graph of cubic polynomial after shift 1.5 unit right.

Equation of given graph is

G(x)=(x-1.5)^3-(x-1.5)

For right and left shift, change in x value or horizontal translation.

If we shift "a" unit left then change in x

x\rightarrow (x+a)

If we shift "a" unit right then change in x

x\rightarrow (x-a)

Here, we need to shift 1.5 unit left to get original function.

G(x)=(x-1.5)^3-(x-1.5)

Shift 1.5 unit left

F(x)=(x-1.5+1.5)^3-(x-1.5+1.5)

F(x)=x^3-x

Hence, B is correct function.
