What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation?

It's 2 (to get - 4x & 4x + - 4x = 0)

What number would you multiply the second equation by in order to eliminate the y-terms when adding to the first equation?

It's 3 (to get 9y & - 9y + + 9y =0)

Hope this helps!

F(x)=x2+5x-1 is shifted 3 units left the result is g(x) what is g(x)?

Len [333]

Replace the x in x^2 + 5x - 1 by x+3:-

g(x) =
(x+3)^2 + 5(x+3) - 1

= x^2 + 6x + 9 + 5x + 15 - 1

= x^2 + 11x + 23

- thats g(x)

Answer:

Step-by-step explanation:

-14 + 2x + 3 = 4x - 13 - 7x

We can first add the numbers and coefficients on either side:

2x - 11 = -3x - 13

Then, we can add 3x to both sides:

5x - 11 = -13

We can add 11 to both sides

5x = -13 + 11 = -2

Lastly, we can divide both sides by 5

x = -2 / 5
