Which line shows the first error in the solution? 5(x-5)=15 (1) 5x-25=15 (2) 5x-25=15-25 (3) 5x= -10 (4) 5x/5 = -10/5 (5) x=-2 (6) answers: a. line 2 b line 3 c. line 4 d. line 5

Answer : B. line 3

5(x-5)=15 > 1

We remove the parenthesis by distributing 5 inside the parenthesis.

 5x - 25 = 15 > 2

To get rid of -25, add 25 on both sides

5x - 25 + 25 = 15 + 25 > 3

5x = 40  > 4

Divide by 5 on both sides

x = 8  

From the given options we can see that there is a error in line 3.

Instead of adding 25 , they subtracted 25

So line 3 shows the first error.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
