This is in slope intercept form, which tells us directly where the y-intercept is, and what the slope is.
y=mx + b
m = slope
b = y-intercept
So, the y intercept is (0, 44)
And the slope is 3, or 3/1
Answer:42
Step-by-step explanation:
Answer:
He did 9 times 10 instead of 9 times 100.
Answer:
p(x) = 0.85x
t(x) = 1.065x
(t o p)(x) = 0.9x
$2700
Step-by-step explanation:
If the marked price is $x, then the function p(x) that gives the price of the riding lawn mower after 15% discount will be

where x is the marked price.
Now, the function that gives the total cost with sales tax will be given by

where x is the discounted price.
Therefore, the composite function that gives the total cost of the riding lawn mower on sale is given by
(t o p)(x) = 1.065(0.85x) = 0.9x ............ (1)
where x is the marked price.
If the marked price x = $3000, then Mr. Rivera has to pay for the riding lawn mower, from equation (1),
(t o p)(3000) = 0.9 × 3000 = 2700 dollars. (Answer)
