<h3>
Answer: 10 years old</h3>
Work Shown:
s = son's age
(father's age)/(son's age) = 9/2
45/s = 9/2
45*2 = s*9
90 = 9s
9s = 90
s = 90/9
s = 10
The son is 10 years old.
To find out how much Stan is paid a day, simply find out how many miles Stan drives per day, and multiply that with the amount Stan is paid per mile (in this case $3.50 per mile). Then, add that with the daily amount Stan earned (which is $75).
For example, on Monday, Stan drove a total of 30 miles (and he's paid $3.50 per mile).
Simply multiply $3.50 (per mile) with 30 (total number of miles driven), and that should equate to $105 earned for driving a total of 30 miles.
Then, add $105 (earned from driving 30 miles) to $75 (daily pay) and that equals $180.
Stan had been paid a total of $180 on Monday.
Answer:
(x, x2 -2x+8) where −5 ≤ x ≤ 3
Step-by-step explanation:
The given function is f(x)=x2- 2x+ 8
We want to select the option that describes all the solutions to the parabola.
The domain of the parabola is −5 ≤ x ≤ 3.
This means that any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.
This can be rewritten as (a,-a2- 2a+ 8)
Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:
(x, x2 -2x+8) where −5 ≤ x ≤ 3.

Answer:
<h2><em><u>7d + 4f - 15</u></em></h2>
Explanation:
-3 + 4d - 2f + 3d + 6f - 4 - 8
= −3 + 4d + −2f + 3d + 6f + −4 + −8
= −3 + 4d + −2f + 3d + 6f + −4 + −8
(4d + 3d) + (−2f + 6f) + (−3 + −4 + −8)
7d + 4f + −15
= 7d + 4f - 15
