Answer:
y = 2
Step-by-step explanation:
When line is horizontal, all points on this line have the same value of y.
In this case , all points have to have y = 2.
y = 2, is an equation of horizontal line.
Answer:
Hundreds is 8, tenths is 5, and thousandths is 1!
Answer:
y = 3/5 x + 6
Step-by-step explanation:
y = mx + b
m = slope; b = y-intercept
y = 3/5 x + 6
Answer:
Step-by-step explanation:
"78% of P" looks like this in an algebraic expression: .78P
"117% of Q" looks like this: 1.17Q
"...is 23.4 more than [above]" looks like this: [above] + 23.4
Putting that all together in one equation, knowing that the word "is" means "equals":
.78P = 1.17Q + 23.4
From there, we will now use the fact that Q is 40% of P, which looks like this:
Q = .4P
Now, using that substitution:
.78P = 1.17(.4P) + 23.4 and
.78P = .468P + 23.4 and
.312P = 23.4 so
P = 75
Going back up to what Q is equal to, we will sub in the value of P and solve for Q:
Q = .4P and P = 75, therefore,
Q = .4(75) so
Q = 30
