Guided Practice Juan charges $3.50 per hour for baby-sitting. Write a rule to describe how the amount of money M earned is a function of the number of hours h spent baby-sitting. About how long will it take Juan to earn $15?

A.
M = 3.5h; about 4 hours

B.
M = 3.5h; about 12 hours

C.
h = 3.5M; 53 hours

A

Step-by-step explanation:

you go to divide 15 by 3.5 and then you'll get your answer 4 hrs

A.

M = 3.5h; about 4 hours

Step-by-step explanation:

M(earned money)=h(worked hours)*$3.50

M = money earned

H = hours spent baby sitting

Basically, M = $3.50 x H, or M=$3.50H

So, if H = 6 then, 6 x $3.50 = $21 so M = $21

M= 3.50H

you would multiply the number of hours by 3.50 and that would be the total about of money earned.

Juan charges $3.50 per hours for baby-sitting.

a.write a rule to describe how the amount of money M earned is a function of the number of hours baby-sitting.

b. make a table of values

c. graph the values and join the point with a line.

d. use the graph to estimate how long it wii take Juan to earn $15.

M = money earned H = hours spent baby sitting a) Rule is: M = $3.50 x H, or M=$3.50H b) Table of values H(in hr) M = 3.5H

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
