Answer:
I think X is 3. Sorry if it's wrong!
Step-by-step explanation:
5 x 3 = 15 x 10 = 150
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
where
k is the constant of variation
in this problem we have
the point
so
substitute
therefore
<u>the answer is</u>
The associative property of addition is pretty much just any numbers in place of these: a + (b + c) = (a + b) + c. Therefore, your answer would be d) (6 + 1) + 9 = 6 + (1 + 9)
1/4 2/8 3/12 4/16 5/20 6/24
My "work" is to enter the equations into a graphing calculator and let it show me the answers--just as your "work" is to copy the question to Brainly.
The solutions are
(x, y) = (-0.5, 7.5)
(x, y) = (3, 25)
_____
When you equate the expressions for y, you get the quadratic
2x² -5x -3 = 0
(2x +1)(x -3) = 0
x = -1/2 or 3
y = 5(x +2) = 15/2 or 25
