Answer:
what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9-month total cost of $327
Step-by-step explanation:
cost = $33 per month + fee
1. c(m) = 33m + f
33(6) + f = 228
198 + f = 228
f = $30 membership fee
c(m) = 33m + 30
2. at 9 months: 33(9) + 30 = $327
hopefully this helps :)
have a nice day !!
Using linear functions, the inequality that represents when Gilberta has more wallpaper left in her room than María has in hers is: t < 5.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For this problem, we consider:
- The initial amount as the y-intercept.
Hence the amounts Gilberta and Maria have left after t hours are given by:
Gilberta has more papers when:
G(t) > M(t).
Hence:
35 - 4.3t > 30.5 - 3.4t
-0.9t < -4.5
Multiplying by -1:
0.9t < 4.5
t < 4.5/0.9
t < 5.
Hence the inequality is:
t < 5.

Answer:
x =3 sqrt(3)
Step-by-step explanation:
cos theta = adj/ hyp
cos 60 = x/ 6 sqrt(3)
Multiply each side by 6 sqrt(3)
6 sqrt(3) cos 60 = x/6 sqrt(3)/ 6 sqrt(3)
x =cos 60 * 6 sqrt(3)
x =3 sqrt(3)

Answer:
- A
- B
- D
Step-by-step explanation:
1. The absolute value of a positive number is that number. The absolute value of a negative number is the same number with a positive sign. Your choices simplify to ...
A. -5 > 5 . . . . . false
B. 5 = 5 . . . . true
C. 5 = 5 . . . . true
D. 5 > -5 . . . . true

2. The sequence of the numbers of interest on the number line is ...
-7 < |-2| < |-5| < |-10| < |-13|
The true description is |-2| is left of |-5|.
