Answer:
x = 2y − 2
Step-by-step explanation:
x + y + 5 = 2x - y + 7
−x + y + 5 = −y + 7
−x + 5 = −2y +7
−x = −2y + 2
x = 2y − 2
Answer:
3,-1
Step-by-step explanation:
you go over to the left 3 and than you go down 4.
To transform the function

to have the amplitude of 3, we need to multiply the constant 3 to the function f(x), so we have

To transform the function

to have the midline

we need to subtract

by 4, so we have

,
To transform the function

to have period of

, we need to divide the original period

by 4, so we have

. Note that it is the

gives the effect of dividing the points on x-axes by 4 and the period is read on x-axes
Hence, the full transformation is given

which is the last option
The answer should be the 1st one.
Just use the quadratic formula and plug in the necessary numbers when requested and work from there.
