Answer: 33
Step-by-step explanation:
(f of g)(2) = f(g(2))
g(2) = -2(2) = -4
f(-4) = (-4)^2 - 3(-4) + 5 =
16 - - 12 + 5 =
16 + 17 =
33
5x + 10x = 180
15x = 180
X = 12
5 x 12 = 60
10 x 12 = 120
The angles are 60° and 120°
The formula for f(x) in y + 6 = 5(x - 4) in terms of x is f(x) = 5(x - 4) - 6
Answers:
Step-by-step explanation:
Our equation is:
With f meaning "fare" (price) and m meaning "miles".
Question 7 - Juan's fare for his ride costs $6.05. We must solve for
.
Step 1. Substitute - <em>Substitute the fare for
in the equation.</em>

Step 2. Simplify/Solve - Solve for
.

<em>- Distribute</em>

<em>- Subtract 0.2 from 2.25</em>

<em>- Subtract -2.05 from 6.05</em>

<em>- Divide both sides by 0.2</em>

<u>And you have your answer of 20 miles.</u>
Question 8 - Same equation, different fare.
Step 1. Substitute

Step 2. Solve

And like so, we have 
<em>The equation given is
. S = typing speed, w = words per 5 mins, and e= errors.</em>
Question 9 -
<em>We are given this information: S = 55, W = 285. We are solving for e</em>.
Substitute -

Solve -

So they would make 1 error.
Question 10 -
<em>Information given: 300 = w, 5=e. We are solving for S</em>
Substitute -

Solve -

Their speed is 50.
Question 11 -
<em>Information given: S = 65, e = 4. We are solving for w.</em>
Substitute -

Solve -

So w = 365.
