Answer:
I think 14, 15, V200.
Step-by-step explanation:
I'm not sure what V200 is but I kinda just ignored the v, then you have 14, 15, 200.
Answer:17 5/6
Step-by-step explanation:
3
The y axis intercepts the linear function at positive 3
Answer:
Yes!
Step-by-step explanation:
first you need two points (x,y) (x,y). 
is the formula you would follow to get the slope. Say you have (2,4) (3,-7) You would plug it into the formula and get 
. This example you can simplify it into -11. hope that kinda helps.
5sqrt(x+7)=-10
Dividing both sides by 5:
5sqrt(x+7)/5=-10/5
sqrt(x+7)=-2
Squaring both sides of the equation:
[sqrt(x+7)]^2=(-2)^2
x+7=4
x+7-7=4-7
x=-3
Replacing in the original equation:
5sqrt(x+7)=-10
5sqrt(-3+7)=-10
5sqrt(4)=-10
5(2)=-10
10=-10 It's not equal, then x=-3 is an extraneous solution
