Just substitute in the number 3 for x then subtract 3 at both sides and youll have y=7
GCF(24, 30, 42) = 6 I think it is.
Answer:
(-6,4)
Step-by-step explanation:
The equations are:

Solving for x^2 of the 2nd equation and putting that in place of x^2 in the 2nd equation we have:

Now we can solve for y:

So plugging in y = 4 into an equation and solving for x, we have:

So y = 4 corresponds to x = 6 & x = -6
The pairs would be
(6,4) & (-6,4)
<u><em>we see that (-6,4) falls in the 2nd quadrant, thus this is the solution we are looking for.</em></u>
Answer:
The correct answer is C if the answers are the same as the picture attached.
A^2 + b^2 = c^2
a=6
b=8
36 + 64 = 100
Sqrt 100 = 10
A is the answer
