There are two ways to do this.
The first way is to algebraically find (f+g)(x) first and plug in x = 5 later. Doing that method leads us to
(f+g)(x) = f(x) + g(x)
(f+g)(x) = 6x+3 + x-4
(f+g)(x) = 7x-1
(f+g)(5) = 7(5)-1
(f+g)(5) = 34
OR
you can compute f(5) and g(5) first, then add up those sub-results to get
f(x) = 6x+3
f(5) = 6(5)+3
f(5) = 33
g(x) = x-4
g(5) = 5-4
g(5) = 1
Adding up these results gives: (f+g)(5) = f(5) + g(5) = 33+1 = 34
Either way, the final answer is 34
Slope-intercept form looks like this: y = mx + b. For your equation, simply add 3x on both sides: y = 3x + 19.
Hold on i believe its C but let me go look on google and i'll get back to you to sure
The movie should be 2 hours and 15 minutes long.
Alright so all we are doing is adding 7/10 and 1/2
But sometimes that can be difficult because they don’t have the same denominator
In that case, we want to give them the same denominator (bottom number if the fraction)
So we do this by multiply 1/2 by 5/5 which will get you 5/10
We now have 5/10 and 7/10 which both have the same denominator (10)
So add them together and you will get 12/10
Now that’s more than 1 gallon so let’s figure out how much more
So 12/10 -10/10 (full gallon) = 2/10
So she used 1 2/10 gallons
If you want it in decimal form then it’s 1.2 (divide 2 by 10)
Hope that helped!
