Answer:

x=1 & y=6 or (1,6)

Step-by-step explanation:

3x-x+5=7   Substitute the 2nd equation in for y  

2x+5=7      Do 3x-x to get 2x

2x=2          Subtract 5 from both sides

x=1              Divide 2 from both sides

y=1+5          Insert 1 as x

y=6             Add 1+5 to solve for y

Hope this helped!

Given that (-3,7) is on the graph of f(x), find the corresponding point for the function f(x + 5).
Stella [2.4K]
We have that
<span>(-3,7) is on the graph of f(x), find the corresponding point for the function
f(x + 5)

we know that
in the transformation f(x)-------> f(x+5)
the point (x.y) in f(x) becomes a point (x-5,y) in f(x+5)
so
(-3,7)-----------> becomes a point (-3-5,7)------> (-8,7)

the answer is
</span>(-8,7)<span>

</span>
