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:

$3500+1050=4550$

What is the value of discontinuity of x^2+8x+4/x^2-x-6? Choices:

Morgarella [4.7K]

Answer:

-2

Step-by-step explanation:

Hello,

First of all, let's check the denominator.

$x^2-x-6 \ \ \text{ *** How to factorise it ...? ***}\\\\\text{*** The product of the roots is -6=-2*3 and their sum is 1 ***}\\\\x^2-x-6=x^2-3x+2x-6=x(x-3)+2(x-3)=(x+2)(x-3)$

Now, let's see the numerator.

$x^2+8x+4 \ \text{ *** -2 is not a zero as ***}\\\\(-2)^2+8*(-2)+4=4-16+8=-4\\\\\text{*** 3 is not a zero as ***}\\\\3^2+8*3+4=9+24+4=37\\$

So we cannot factorise the numerator with (x+2) or (x-3)

Then, -2 and 3 are the the discontinuities of the expression.

There is only -2 in the list, this is the correct answer.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
