Answer:
4. false 1 is nor prime nor composite
(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:
Each hot dog is worth 5.7
Each bun is worth 2.4
Step-by-step explanation:
3d + 2b = 21.9
2d + 5b = 23.4
multiply the first by 2 and the second by 3
6d + 4b = 43.8
6d + 15b = 70.2
the coefficeint of d is the same in both equations, so subtract the first from the second
11b = 26.4
divide
b = 2.4
each bun is worth 2.4
take the first equation and plug the price of buns in
3d + 2b = 21.9
3d + 2(2.4) = 21.9
3d + 4.8 = 21.9
3d = 17.1
d = 5.7
each hot dog is worth 5.7
A method you could use to do this more easily or check your answers would be to graph the fuctions used on a website like desmos
