1. Charlie bought a new computer for $450 with his credit card. He plans to pay the minimum payment
atroni [7]

Given:

Charlie bought a new computer for $450 with his credit card.

He plans to pay the minimum payment  of $25 per month.

To find:

The rate of change.

Solution:

Let y be the remaining amount of loan after x months.

Initial amount of loan = $450

Payment of one month = $25

Payment of x months = $25x

Now,

Remining amount = Initial amount of loan - Payment of x months

y=450-25x     ...(i)

The slope intercept form is

y=mx+b     ...(ii)

where, m is slope and b is y-intercept.

From (i) and (ii), we get

m=-25

Therefore, the rate of change is -25 dollars.

Which is a solution to the equation?<br> (х-2)(х + 5) = 18?
jok3333 [9.3K]

\bf (x-2)(x+5)=18\implies \stackrel{\mathbb{F~O~I~L}}{x^2+3x-10}=18\implies x^2+3x-28=0 \\\\\\ (x-4)(x+7)=0\implies x= \begin{cases} 4\\ -7 \end{cases}

1. Y varies inversely with x. If y = 9 when x = -5, find the value of x when y=-6.
Gelneren [198K]

Answer:

Step-by-step explanation:

1 )  Y∝ 1 / X

Y = k / X

Y = 9 , X = -5

Putting the values in the relation above

9 = k / - 5

k = -45

Y = - 45 / X

Put Y = - 6

- 6 = - 45 / X

X = - 45 / -6

= 7.5

2 )

Luke and Nora can peel 12 carrots in 5 minutes

in 1 minute Luke and Nora can peel 12 / 5 carrot

in 1 minute Luke alone   can peel 12/ 11 carrot .

In 1 minute Nora alone will peel (12 / 5 -  12/ 11  ) carrot

(12 / 5 -  12 / 11  )

= 2.4 - 1.1

= 1.3 carrot

In 1 minute Nora alone will peel 1.3 carrot

1.3 carrot in 1 minute

8 carrot in 8 / 1.3 minute

= 6.15 minutes.

In 1 minute Nora alone will peel 8 carrot in 6.15 minutes working alone.
