4.b.
Answer: See below.
Step-by-step explanation:
<h2><u>
For the equation f(x) = 2x</u></h2>
3.a. f(6) means use x = 6 in the equation f(x) = 2x
so f(6) would be f(6)= 2(6)
<u>f(6) = 12</u>
3.b. f(-11) = 2(-11)
<u>f(-11) = -22</u>
3.c. f(2.75) = 2(2.75)
<u>f(2.75) = 5.5</u>
3.d. This is turned around. We are told f(x)=20, so what would x need to be for f(x) to be 20? Since f(x) = 2x, we can say 20 = 2x. Therefore x = 10
f(10) = 20
<u>The rest of (3) are solved in the same fasion.h</u>
<u></u>
<h2><u>
For the equation f(x)= 5x+50</u></h2>
4.a. f(7) = 5(7)+50
<u>f(7) = 85</u>
4.b. f(-12)
f(-12) = 5*(-12)+50
<u>f(-12) = -60</u>
<u></u>
Continue in the same fashion for these types of problems.
Answer:
<u>x = 8/23</u>
Step-by-step explanation:
<u>Adding 3.5 to each side</u>
- -3.5 + 3.5 = -4.6x - 5.1 + 3.5
- -4.6x - 1.6 = 0
<u>Adding 4.6x to each side</u>
- -4.6x - 1.6 + 4.6x = 0 + 4.6x
- 4.6x = -1.6
<u>Dividing each side by 4.6</u>
- 4.6x/4.6 = -1.6/4.6
- <u>x = 8/23</u>
