If f(x)=2x+5x and g(x)=3x-5,find (f+g)(x)
kati45 [8]

The answer is (f+g)(x)=10x-5

Step-by-step explanation:

Given that f(x)=2x+5x and g(x)=3x-5

To find : (f+g)(x)

Now, assign the value g(x)=3x-5 in (f+g)(x)

(f+g)(x)=(f+3x-5)

Also, assign the value f(x)=2x+5x in (f+g)(x)

(f+g)(x)=(2x+5x+3x-5)

Now, adding the like terms , we get,

(f+g)(x)=10x-5

Thus, the value of (f+g)(x) is (f+g)(x)=10x-5

Help me ! I rly need to finish this home work before the dead line the deadline is in 30 mins plz help
storchak [24]

Answer:

The answer is a= 15

Step-by-step explanation:

First, you multiply both sides by 5. 5*3 = 15 and a/5*5 = a, since 5 and 5 cancels out each other. This is optional, then you flip the equation to get a= 15. Hope this helps.

Henry just got a job at the mall. His job pays an hourly rate of $10.25.
nadezda [96]

Answer:

A. He will have to work 40 hours to buy the headphones

B.  1200 ≤ 10.25x ≤ 2000    where x is # of hrs worked

He can work anywhere between 118 and 196 hours.

Step-by-step explanation:

A. Divide 399.95 by 10.25 to get 39.01 hours. But since you cant work 0.01 of an hour, you have to round up to the next hour

B. You want to make more than or equal to 1200, so put that in the inequality. You want to make less or equal to 2000, so you put that in the inequality. In the middle, you put 10.25 an hour multiplied by the number of hours, which is a variable.

To solve, I made 10.25x = 1200, and x equaled 117.07, which rounds up to 118 hours because you cant work a 0.07 of an hour. 118 hours is the low number of the spectrum.

To solve for the highest number on the spectrum, you do 10.25x = 2000, and x equals 195.12, but since you cant work 0.12 of an hour, it rounds up to 196 hours.
