Answer:
g(x)=5x+7
Step-by-step explanation:
f(x)+g(x)=9x+4
We are given f(x)=4x-3.
So we insert 4x-3 for f:
4x-3+g(x)=9x+4
Subtract 4x on both sides:
-3+g(x)=5x+4
Add 3 on both sides:
g(x)=5x+7
Check:
f(x)+g(x)
=(4x-3)+(5x+7)
=(4x+5x)+(-3+7)
=(9x) +(4)
=9x+4
Bingo. We did it! :)
Answer:
Step-by-step explanation:
f(x)=42-0.45(x) Solution 13.5 dollars expend in 30 Finishing nails
f(x)=42-0.60(x) Solution 18 dollars expend in 30 Common nails
Plug in 2 and 4 for every instance of x in the function g(x).
g(x) = 0.023x³ + 0.4x² − 2.1x + 8.3
g(2) = 0.023(2)³ + 0.4(2)² − 2.1(2) + 8.3 = 5.884
g(4) = 0.023(4)³ + 0.4(4)² − 2.1(4) + 8.3 = 7.772
answer: 5.884 and 7.772
Answer: x=y=c=csquar
Step-by-step explanation: math
245in^2
Curved surface = 2pi x r x h = 2 x 3.1 x 3 x 10 = 186
2 ends = 2 x (Pi x r x r) = 2 x 3.1 x 3 x 3 = 55.8
Total area = 186 + 55.8 = 242in^2 approximately
