X^2 - 13 x = -36
add 36 to both sides
x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}
This is easier than you think!
When a graph shows direct variation, it always <em>passes through the origin</em>
The origin is (0, 0)
The very <u>center! </u>

Answer:
The answer is D
Step-by-step explanation:
Answer:
d=16
Step-by-step explanation:
d: distance (10,4),(-6,4)
d=√(x2-x1)^2+(y2-y1)^2
d=√(-6-10)^2+(4-4)^2
d=√16^2
d=16
