Answer:

Step-by-step explanation:

In point-slope form, our equation would be y - 9 = 2(x - 1). Expanding, we get y - 9 = 2x - 2. Solving for y, we obtain the form of the equation as shown in the problem: y = 2x + 7.

So, the numbers that would go in the blanks would be 2 and 7, respectively.

Ryan buys some jumpers to sell on a stall.
Gemiola [76]

Answer:

£160

Step-by-step explanation:

£140÷60=£2.33

60×40%=24

£8×24=£192

60-24=36

36÷2=18

18÷2=9

9×£8=£72

9×(£8÷2)=£36

£192+£72+£36=£300

£300-£140=£160

7,200 yards equals ? miles? are there any extra yards
olga2289 [7]
Hello there!

By converting 7,200 yards into miles, 7,200 yards would be 4 miles. 

But to really give you the correct answer, it would actually be 4.(090909). This extra part would basically almost be known as 1.

So, it would be 4.1 miles.

I hope this helps you!

Question 9 of 10
WARRIOR [948]

Answer:

C

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

y = (x + 7)² - 9 ← is in vertex form

with h = - 7 and k = - 9

vertex = (- 7, - 9 )

Pedro Pascal wants to have $15,000 in an account after five years. He found a bank that will offer him a 7.5% interest rate, com
Juli2301 [7.4K]

<u>Answer-</u>

He needs to put $10345 in the account today, in order to get 15000 in five years.

<u>Solution-</u>

We know that,

A=P(1+\frac{r}{n})^{nt}

Where,

A = future value of the investment with interest  = 15000

P = principal investment amount

r = annual interest rate (decimal)  = 7.5% = 0.075

n = number of times that interest is compounded per year  = 4

t = the number of years the money is invested = 5

Putting the values,

15000=P(1+\frac{0.075}{4})^{4 \times 5}

\Rightarrow P=\frac{15000}{(1+0.01875)^{20}} =\frac{15000}{1.01875^{20}} =\frac{15000}{1.45} =10344.8 \approx 10345
