Answer:
23
Step-by-step explanation:
f(x)=4-x²
g(x)=6x
g(x)-f(x)=6x-(4-x²)
g(x)-f(x)=6x-4+x²
so, when (g-f)(3), it means that x=3
.:(g-f)(3)=6(3)-4+(3)²
= 18 - 4 +9
=14+9
=23
2 1/4 is a like term of -5.92
The other answers have variables in them, so 2 1/4 is the only correct answer.
Hope I helped!
All you have to do is divide the 120 by 4 because you will be splitting it up into a individual hour. So 120 divided by 4 = 30.
The plumber charges $30/hour.
Answer:
30
Step-by-step explanation:
He is walking 3 dogs an hour
Ok so 9x minus 11x you get -2x then the two y^2 cancel each other out to get -2x if the y^2 is separate from the x variable. However if its all one then it would be just 9 minus 11 to get -2 then putting the variable back on the end to get -2xy^2.
