X^2 = 4x + 12
x^2 - 4x - 12 = 0, use the quadratic equation
Solve for x over the real numbers:
(x - 6) (x + 2) = 0
Split into two equations:
x - 6 = 0 or x + 2 = 0
Add 6 to both sides:
x = 6 or x + 2 = 0
Subtract 2 from both sides:
Answer: x = 6 (or x = -2 only positive solution)
Answer:
11/15
Step-by-step explanation:
If you convert them to a decimal 11/15 would be more
Answer:
It may be A. or C.
Step-by-step explanation:
A. 5 = 20 4 = 16 4 = 16 20 + 16 = 36 + 16 = 52
B. 3 = 12 3 = 12 7 = 27 + 12 = 39 + 12 = 51
i uhhh don't know this is confusing
im very sorry if im incorrect
Answer:
B. y = -2x + 8
Step-by-step explanation:
So the slope is the number that comes before the x, and if the slope is -2, that means the number before is -2, and it is.
And to know if it goes through (1, 6), put those numbers into the equation and see if they match up (x is the y-intercept)
6 = -2(1) + x
6 = -2 + x
x = 8
The one with both of these is B, which means B is the answer
