Answer:
10, it's 5 less than 5 times 3
Step-by-step explanation:
62.069% is what i thank it is
X=3 is the answer
1.) add 3 to the other side, so add it to 9
2.) you are then left with 4x=12
3.) solve for x, so divide 12 by 4 and you get 3!
We will express second equation in first.
y = 3x + 2
after that we get:
3x + 2 = x^2 + 3x - 7
x^2 -9 = 0
x^2 = 9
x1 = 3
x2 = -3
y1 = 3*3+2 = 11
y2 = -3*3 + 2 = -7
we get pairs:
(3,11) and (-3,-7)
Answer is first option.
