(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:
7
Step-by-step explanation:
7x4=28
6x4=24
So it cant be 6 or anything less
5(3x+4y) is equivalent to 15x-20 !
Answer:
<h2>x=25</h2>
Step-by-step explanation:
according to the question
the equation is
130+2x=180
2x=180-130
2x=50
x=25
Answer:
B
Step-by-step explanation:
4 laps were ran between her 3rd and 7th lap (inclusive) and the duration increased by 14 seconds
But just 2 laps were ran between her 7th and 9th lap and the duration increased by 11 seconds
So obviously the lap duration increased faster between the 7th and 9th lap
