Answer:
17.) x = 3
18.) x = -5
I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3
Step-by-step explanation:
All you really have to do for all of the problems is substitute your value of "x" for the function.
17.) f(x) = 8x - 7; f(x) =17
17 = 8x -7 ---- substitute 17 for f(x), add 7 on both sides
24 = 8x ------ divide 8 on both sides
x = 3
18.) g(x) = -4x + 7; g(x) = 27
27 = -4x + 7 substitute 27 for g(x), subtract 7 on both sides
20 = -4x
x = -5
Answer:
.440
Step-by-step explanation:
Answer: -3
Step-by-step explanation:8-5=3 take the negative so it’s -3
The expression 12(7x+48) is greater than (12x-3) +4(x+5)
As,
12(7x+48) = 84x+576 and,
(12x-3) +4(x+5) = 16x+2
∴ Its clearly shown that 84x+576>16x+2
