Direct variation is is when the x and y a direct relation
without constants added or subtracted
With being times by each other
so the only one that meets the definite is the first one
y = 0.5x means y is equal to half of x. So you know that every y is directly related to half of x
Answer:
X = ±5
Step-by-step explanation:
X^2 - 9 = 16
Add 9 to each side
X^2 - 9+9 = 16+9
X^2 = 25
Take the square root of each side
sqrt(X^2 ) =±sqrt(25)
X = ±5
The answer is B

Answer:
15y-2
Step-by-step explanation:
Please use parentheses if needed, this has me confused but without them, I solved it.
(-2y)(3)+3y-3y+7y(3)+1+2+5
-6y+3y+-3y+21y+1+2+-5
Combine like terms
(-6y+3y+-3+21y) + (1+2+-5)
15y + -2
Answer again: 15y - 2.
