Question

Roy drives a sedan that gets mileage of 30 miles per gallon. If fuel consumption is represented by g and mileage by m, which function represents the relationship between m and g?
m = f(g) = 30 × g
m = f(m) = 30 × m
g = f(m) = 30 + m
m = f(g) = g − 30
m = f(g) = g ÷ 30

Answer 1

m = f(g) = 30 x g

because your mileage depends on how many gallons you have, so m = f(g). And since you get 30 miles per gallon, so you would multiply (30 x g) to get the total mileage.

Answer 2

The function f(x) = 2x2 + 3x + 5, when evaluated, gives a value of 19. What is the function’s input value?
1
-1
2
-2
-3

Answer 3

your input would be the x-value in the function, so set f(x) = 19 and solve for x.

Answer 4

i literally dont know how to do any math it confuses me

Answer 5

its ok, just do things step by step :)
and just clarifying is 2x2 2 times 2, or 2 x squared or something else?

Answer 6

so that answer is positive 2

Answer 7

?

Answer 8

Answer 9

i have more questions

Answer 10

nvm on that last post haha i get it now

Answer 11

sure

Answer 12

Eva makes a few dozen cupcakes and sells them for $8 a dozen. Which function represents the relationship between the money Eva earns, m, and the number of cupcakes she sells, c?
f(c) = c × 8
f(m) = c × 8
f(c) = m × 8
f(m) = m × 8
f(m) = c × m

Answer 13

the ? are x'S

Answer 14

I have this math program i gotta finish by the 5th so could you just give me the answers to all my questions ? cause i got a lot of questions just section 4 and 5

Answer 15

ok, just please make sure you know how to do this too..

Answer 16

okay

Answer 17

f(c) = c x 8

Answer 18

money she makes = 8 * # of dozen cupcakes

Answer 23

Which function represents the number of seconds, s, in d days? (Hint: The number seconds in a day is 24 × 60 × 60 = 86,400.)
The function that represents the number of seconds, s, in d days is f(d) = .

Answer 24

oh, m = f(g) = 30 x g

Answer 25

24 x 60 x 60= 86,400 and then its a blank box i have to put in an answer

Answer 26

Do you have skype or something that i can just share my screen and show you them instead of typing them?

Answer 27

f(d) =s = d/(24 x 60 x 60)

Answer 28

yeah

Answer 29

can i have your skype name so i can add you ?
