Answer:
We are given that:
variables x and y vary directly, this means that:
y = kx where k is the constant of proportionality
Now, we are also given that:
y = 45 at x = 40.
We will use these values and substitute in the above relation to get k as follows:
y = kx
45 = 40k
k = 45/40 = 9/8 = 1.125
Based on the above calculations, the equation that relates x and y is:
y = 1.125x
Step-by-step explanation:
<span>3x + 2y = 7
y = –3x + 11
replace </span>y = –3x + 11 into 3x + 2y = 7
3x + 2y = 7
3x + 2(–3x + 11) = 7
3x -6x + 22 = 7
-3x = 7 - 22
-3x = -15
x = 5
<span>y = –3x + 11
y = -3(5) + 11
y = -15 + 11
y = -4
x = 5 and y = -4
