Answer:

(f+g)x= 2x²+5x-3

The domain x∈ Real number.

Step-by-step explanation:

Given that f(x) = 5x - 3 and g(x) = 2x²

(f+g)x = f(x) + g(x)

So, by using the given function

(f+g)x= (5x-3) + (2x²)= 2x²+5x-3

As the result, 2x²+5x-3, is a polynomial, so domain of the result is all the real numbers.

Kerri correctly calculated the distance between point S (–3428) and point T (286) on a number line.
kogti [31]
Ok, you're dealing with a 1 dimensional number line.

To find the distance between these two points what you want to do is go from -3428 to 0, then from 0 to 286.

The distance between -3428 and 0 is 3428. The distance from 0 to 286 is 286.

Add up both these differences:

3428 + 286 = 3714

So the answer is in fact D, 3714.

You receive 15% of a profit from a car wash how many money do you receive from a profit $600?
PilotLPTM [1.2K]

EXPLANATION

If receive 15% of a profit, and considering a total profit of $600, the amount is given by the expression:

Profit = 15% of 600

We must turn 15% into a decimal form by dividing it by 100 as follows:

15/100 = 0.15

So, the computed value is:

Profit = 0.15 x 600 = $90

The answer is $90.
