Answer:
the last answer
Step-by-step explanation:
-9x - 3y = 6, x = -2
Plug in -2 for x.
-9(-2) - 3y = 6
Simplify.
18 - 3y = 6
Subtract 18 from both sides.
-3y = 6 - 18
Simplify.
-3y = -12
Divide both sides by -3.
y = -12/-3
Simplify.
y = 4

Step-by-step explanation:
<u>Solving Equations</u>
We have the expression:
And it's required to make y the subject.
It can be done by isolating y on the left side of the equation and the rest of the expression on the right side.
The first step is removing the denominator by multiplying both sides by y-3:
Simplifying the right side:
Remove the parentheses:
Move the y's to the left side and the rest of the expression to the right side:
Factor out y:
Divide by x-1:
Answer:
73.5
Step-by-step explanation:
y=kx
where k is a constant
y=7
x=2
7=2k
k=3.5
what about when x=21
y=3.5*21
y=73.5
21.5 inches long
12*3/8=4.5
26-4.5=
21.5 inches
