Step-by-step explanation:

It is GP with common ratio of 3 as 6/2=18/6=54/18=162/54= 3 and the first term of 2

then aₙ= 2*3ⁿ⁻¹ is the formula

A line passes through the points (8,-1) and (-4,2). What is the y intercept of the line ?
Mariana [72]

Answer:

"Y intercept is1 "

Step-by-step explanation:

The slope is (-1 - 2)/[8 - (-4)] = -3/12 = -(1/4)

(-1/4) = (y - 2)/(x + 4) => -x - 4 = 4y - 8

-x + 4 = 4y

y = (-1/4)x + 1 so that the y-intercept is 1

Nuetrik [128]

The remaining values will be<u> 19, 20, 21, 22 and 23</u>

<h3 /><h3>System of equations</h3>

Given the following parameters

Ethan's score = x points

His younger sister's score = 8 points

If their total score is y points, hence the  equation relating x and y is expressed as:

x + 8 = y

x = 8 - y

If x = 10

y = x + 8

y = 18

The ramining values will be<u> 19, 20, 21, 22 and 23</u>

30 miles for a single gallon.
first we find out how many gallons would be used.
number of gallons = 1020/30
gallons = 34.
and since 1 gallon costs $4.06
34 gallons would cost = 34 x 4.06 = $138.04

A company will need 25,000 in 7 years for a new additon. To meet this goal, the company deposits money into an account today tha
Mrac [35]
You can use the simple interest formula 
P = irt

We need P, which is the primary (or principal) investment, and we know that:

rate = 3% (0.03)
time = 7
i = $25000

So, just plug in and solve:
I = 25000(0.03)(7)
I = 5250

The company needs to invest $5250 today, to make $25000 in 7 years.
