Answer: £171

Step-by-step explanation:

£399

Ann : Bill : Chloe : Dave

2 : 9 : 2.5*Ann : 2.5*Ann

x : 4.5x : 2.5x : 2.5x

10.5x = 399

x = 38

Ann = £38

Bill = £38 * 4.5 = £171

Chloe = £38 * 2.5 = £95

Dave = £38 * 2.5 = £95

A company has determined that the number of items it sells varies inversely as the price of the item. If 20,000 items can be sol
mestny [16]
Let N be the number of items sold and p the price. 
Since the variation is inverse, then the relation between N and p is:
N=k\dfrac{1}{p}
For N=20000 and p = $9.5, we get the formula:
 20000=k\dfrac{1}{9.5}\\p=20000\times9.5=190000
If p = 8.75, then the number of items sold can be computed using the formula:
N= 190000\dfrac{1}{8.75}=21714 \text{ total items}

Solve the system of equations. y = 2x y = x 2 – 15
inn [45]

Answer:

D. (–3, –6) and (5, 10)

Step-by-step explanation:

The system has equations:

y=2x...(1)

and

y=x^2-15...(2)

Equate both equations;

x^2-15=2x

Rewrite in standard form:

x^2-2x-15=0

We factor to obtain:

(x+3)(x-5)=0

By the zero product principle;

(x+3)=0,(x-5)=0

\implies x=-3,x=5

When x=-3, y=2(-3)=-6

This yields the ordered pair (-3,-6).

When x=5, y=2(5)=10

This yields the ordered pair (5,10).

The correct choice is D.
