Jason earned a total of $15900 from two part-time jobs. If he earned 3700 more from one job than the other , how much did he ear
KiRa [710]
Let's call job one x.

Job two can be y.

Jason earned $3,700 more from job y than x. Therefore y = x + 3700

From the two jobs, Jason earned $15,900. This can be written as x + y = 15900.

Now substitute y for x + 3700:

x + x + 3700 = 15900

2x + 3700 = 15900

Subtract 3700 from both sides:

2x = 12200

Divide both sides by 2:

x = 6100

Take the original equation x + y = 15900 and substitute x with 6100:

6100 + y = 15900

y = 9800

Job one (x) paid Jason $6,100.

Job two (y) paid Jason $9,800.

Given f (x) = x2 + 5x + 6, what is f of the quantity 2 plus h end quantity minus f of 2 all over h equal to?
scoray [572]

We want to get the difference quotient for the given function, we will get see that the difference quotient is equal to:

f'(x) = 2x + 5

<h3>The difference quotient:</h3>

For a given function f(x), we define the difference quotient as:

\lim_{h \to 0}  \frac{f(x + h) - f(x)}{h}

In this case, we have:

f(x) = x^2 + 5x + 6

Replacing that in the difference quotient we get:

\lim_{h \to 0}  \frac{(x + h)^2 + 5*(x + h) + 6 - x^2 - 5x - 6}{h}\\\\\lim_{h \to 0}  \frac{x^2 + 2xh + h^2 + 5*x + 5*h + 6 - x^2 - 5x - 6}{h}\\\\\lim_{h \to 0}  \frac{ 2xh + h^2 + 5*h }{h}\\

Now we can cancel the factor h to get:

\lim_{h \to 0}  2x + h + 5 = 2x + 0 + 5 = 2x + 5

So the difference quotient is equal to 2x + 5.
