Answer:
Step-by-step explanation:
50 - x² = 0
50 = x²
x² = 50
x = √50

It would value to -15 because you just need to plug in the (-4) into the X
Answer:

Step-by-step explanation:
We are given: 
We will use integration by parts.


Infinitely many solutions, because the slope follows the same line, meaning the y=mx+b equations will be EXACTLY THE SAME....
(infinite possibilities for variables)
we are given equation as

so, when we replace x as x+7
our graph will shift left side by 7 units

we can see the graph
