Answer: y = 1/2 or y = -1/2
Step-by-step explanation:
First move the 1 to the side with the 0
-4y^2 = -1 // -1 because when you move a number to the other side of the equation you have to multiply -1
Then divide by -4 on each side
y^2 = 1/4
square root each side
|y| = 1/2 // sq rt y^2 becomes an absolute value because when you square root a square it automatically becomes an absolute value
so the answer would be y = 1/2 or -1/2
to check just put it into the equation as y. Both work.
Answer:
C = 34
Step-by-step explanation:
XW/XV = YW/YZ [[write it out]]
12 / (12+5) = 24 / x [[x is unknown]]
12 / 17 = 24 / x [[solve for x]]
17(24) = 12x [[cross-multiply]]
408 = 12x [[divide for x]]
x = 34 [[answer]]

Hey!
First let’s plug in 7 for t. 300(1.005)12(7), 12*7= 84
