Answer:
The correct answer is:
Step-by-step explanation:
We want to solve for the amount of money he pays each month. This is represented by y in the equation. This means we want to isolate y in the equation:
x = t - yz
We first want to subtract t from each side:
x - t = t - yz - t
x - t = -yz
Now we want to cancel the negative sign and z. We can isolate both of these at the same time; divide both sides by -z:
\frac{x-t}{-z} = \frac{-yz}{-z} \\ \\\frac{x-t}{-z}=y
We can divide the numerator by the negative sign; this gives us
\frac{-x+t}{z}=y
(5,36)(8,48)
slope = (48 - 36) / (8 - 5) = 12/3 = 4
y = mx + b
slope(m) = 4
(5,36)...x = 5 and y = 36
now sub and find b
36 = 4(5) + b
36 = 20 + b
36 - 20 = b
16 = b
equation is : y = 4x + 16.....in standard form : 4x - y = -16 <==
=======================
function notation : f(x) = 4x + 16
=======================
x axis will be ur hrs....I would label them at intervals of 1
y axis will be total cost of renting the bike......as far as the intervals...not sure how to label them.....sorry....I wanna say intervals of 2...but am not sure
y = 4x + 16
slope = 4
y int = (0,16)
x int = (-4,0)
so start at (-4,0)....and since ur slope is 4, go up 4 and to the right 1...keep doing this and u will cross the y axis at (0,16)
Answer:
- 8
Step-by-step explanation:
An equation in the form y = mx + c ( m is the slope and c is the y- intercept )
Has a constant rate of change = m
given
= 12 + (n - 1)(- 8) ← distribute and simplify
y = 12 - 8n + 8
y = - 8n + 20 ← in the form y = mx + c
with constant rate of change = - 8
