Answer:
Least: 10.5
Greatest: 14.125
Hope that helps!
Step-by-step explanation:
Hence the value of the expression above are as listed below
<em>f(6+4) = 25</em>
<em>f(6)+f(4) = 20</em>
<em>f(6-4) = 1</em>
<em>f(6)-f(4) = 6</em>
<em>f(6*4) = 67</em>
<em>f(6)*f(4) = 91</em>
<h3>Functions and values</h3>
Given the expression below f(x) = 3x - 5
f(6+4) = f(10) =3(10) - 5
f(6+4) = 25
f(6) = 3(6) - 5
f(6) = 18 - 5 = 13
f(4) = 3(4) - 5
f(4) = 7
f(6)+f(4) = 13+7
f(6)+f(4) = 20
f(6-4) = f(2) =3(2) - 5
f(6-4) = 1
f(6) = 3(6) - 5
f(6) = 18 - 5 = 13
f(4) = 3(4) - 5
f(4) = 7
f(6)-f(4) = 13-7
f(6)-f(4) = 6
f(6*4) = f(24) =3(24) - 5
f(6*4) = 67
f(6) = 3(6) - 5
f(6) = 18 - 5 = 13
f(4) = 3(4) - 5
f(4) = 7
f(6)*f(4) = 13*7
f(6)*f(4) = 91

Answer:
8
Step-by-step explanation:
10x+45> 120 Subtract 45 from both sides of the inequality.
10x>75 Divide both sides by Ten
x>7.5
She has to work at least 7.5 hours so 8 is the fewest number of hours she has to work to buy the shoes.
If the scale is 1 inch = 6 feet
then all we have to do is multiply
1 1/4 inches by 6
5/4 * 6 = 30/4 = 7 1/2
therefore the actual length of a window is
7 1/2 feet long
