Answer:
5
Step-by-step explanation:
When squaring the number 5 (i.e 
) the answer is 25. 
is the same thing as 5 times 5. Basically with the square root, you are going backwards, so you are therefore finding the base of it all.
Y=x+4
3x+Y=-8
3x+x+4=-8
X=-3. Substitute the value of x
Y=-3+4
Y=1
(X,Y)= (-3,1)
So the answer is C
Answer:
d. (9, 0)
Step-by-step explanation:
(x, y) so...
Where the line crosses the x-plane, x = 9
Since this is the x-intercept y will always equal zero
Therfore x-int = (9, 0)
