Compute a value for y that satisfies the equation below.
-3y - 12 = -4
1 answer:
First, add 12 to both sides of the equation, -3y - 12 + 12 = -4 + 12 -3y = 8 Then, divide both the left hand and right hand sides of the equation by -3 (-3y) / -3 = 8/-3 The value of y is therefore, y = -8/3

need to kind K
Y=k x
1/x^2 = k/x^2
Find K
when y=4 & x=5
Y=k/x^2
=
4=k/5^2=
4=k/25
K=4*25
=100
When x
= 2
Y=100/2^2
Y=100/4
Y=25
18 kg times 5 kg would be 90 kg because each window was 18 kg, hence 90 kg
