If f(x)=5x-2 and g(x)=2x+1, find (f+g)(x) A.7x-3 B.3x-1 C.7x-1 D.4x-3

Gwar [14]

Answer:

(f+g)(x) = 7x -1 (Answer C)

Step-by-step explanation:

Rewrite these two functions, one above the other, for ease in adding:

f(x) = 5x - 2

+g(x) =2x + 1

Randy buys a pair of shoes that were originally priced at $147. He receives a 35% discount and pays 8.5% sales tax. How much doe

maksim [4K]

Begin by subtracting 35% from 100%, giving 65% which is equivalent to 0.65
Then multiply
147 * 0.67 = 98.49
Now for a sales tax you would want to multiply by 108.5% (or 1.085) as you are paying the previous price and them some
98.49 * 1.085 = 106.86165
You can round to the second decimal place since you can't have a monetary value less than a penny
your answer would be $106.86

Help asap plz ill give a gold medal. the label on cars antifreeze claims to protect the car between -30celsius and 130celsius. t

The inequality would start out looking like this:
$-30\ \textless \ \frac{5}{9} (F-32)\ \textless \ 130$
Now it's just a matter of solving the inequalities simultaneously. Get rid of the fraction by multiplying everything by 9:
$-270\ \textless \ 5(F-32)\ \textless \ 1170$
Then distribute the 5 into the parenthesis:
$-270\ \textless \ 5F-160\ \textless \ 1170$
Now add 160 everywhere:
$-110\ \textless \ 5F\ \textless \ 1330$
and finally divide everything by 5:
-22<F<266
