Answer:

(1, -1)

Step-by-step explanation:

You have the point ...

(3, f(3)) = (3, -1)

The corresponding point on the horizontally compressed graph will be ...

(3x, f(3x)) = (3, -1)

(x, f(3x)) = (1, -1) . . . . . the first coordinate of the given point is divided by 3

Divide a^24-a^18+a^12 by a^6<br> what is the quotation?

lana66690 [7]

I think you mean "what is the QUOTIENT?"

$\dfrac{a^{24} - a^{18} + a^{12}}{a^6} =$

$= \dfrac{a^{24}}{a^6} - \dfrac{a^{18}}{a^6} + \dfrac{a^{12}}{a^6}$

$= a^{24 - 6} - a^{18 - 6} + a^{12 - 6}$

$= a^{18} - a^{12} + a^{6}$

A discount voucher offering 15% off is used to pay a bill.After using the voucher, the bill is reduced to ?36.72.How much was th

Aleonysh [2.5K]

Answer:

$43.20

Step-by-step explanation:

To find the original purchase price, write a proportion and solve. A proportion is an equation where two ratios are set equal.

If the discount if 15% then you pay 85%.

$\frac{36.72}{y}= \frac{85}{100}$

To solve for y, cross multiply the numerator and denominator of each fraction.

36.72(100) = 85y

3672= 85y

43.2 = y

The horizontal line has equation $y=3$ . The line is solid, and everything below it is shaded, which translates to the inequality $y\le3$ . (so not B nor D)

The dashed line must have equation $y=2x-1$ . Because it's dashed, the inequality is strict. Pick any point in the shaded region, (0, 0) for instance, and compare both sides of this equation. (0, 0) means both $x=0$ and $y=0$ , so on the left side we have 0, and on the right we have -1. 0 > -1, so the inequality must be $y>2x-1$ .

This means the answer is A.
