The rule for differentiation for variable with exponents has the formula:

d/dx (xⁿ) = nxⁿ⁻¹
where n is the exponent

Thus, for the given equation, the solution is as follows:
y = 2x²
dy/dx = 2(2)x²⁻¹ = <em>4x

Thus, the derived equation of the given would now be 4x.</em>

Answer: YES

Plug in the numbers in your head.

y=3(10)+7

y=30+7

y=37 which is the y intercept

Answer:

The total earning of commission on sales of 85, 000 will be:

$3500+1050=4550$

Step-by-step explanation:

Total sales earning = 85,000

As salesperson earns 5% commission the first 70,000.

$\frac{5}{100}\:\times \:70\:000=3500$

As the salesperson earns 7% commission on the sales over 70,000.

As 15000 is the sales earning on which he will get commission 7%.

Because

85,000 - 70,000 = 15000

So the 7% earning of salesperson will on 15000 will be:

$\:\frac{7}{100}\:\times \:15\:000=1050$

Therefore, the total earning of commission on sales of 85, 000 will be:

$3500+1050=4550$
