y = mx + b, where m = slope, and b = y-intercept.

y = 3x + 3

y = 1/2x - 3

y = 1/2x + 3

y = 3x + 1/2

we can eliminate 2 and 4 since the y-intercept in the graph is shown as (0, 3)

This leaves us with

y = 3x + 3 and y = 1/2x+3

m = change in y / change in x

We take any two points on the line to find the slope.

I chose (2, 4), (0, 3)

change in x: 2 - 0 = 2

change in y: 4 - 3 = 1

m = 1/2

This leaves us with the only answer that has the slope of 1/2 and the y-intercept of 3.

option: 3

y = 1/2x + 3

Given the endpoint (-9,3) and (1,8) partition the segment into the ratio 2:3

Sindrei [870]

Answer:

$P = (-5,5)$

Step-by-step explanation:

Let the segments be A and B

$A = (-9,3)$

$B = (1,8)$

$m:n = 2:3$

Required

Determine the endpoints after it is divided into ratios.

Let the point be represented with P

The formula to use is:

$P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

Where

$A = (-9,3)$ ----- $(x_1,y_1)$

$B = (1,8)$ ------ $(x_2,y_2)$

So:

$P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

$P = (\frac{2 * 1 + 3 * -9}{2 + 3},\frac{2 * 8 + 3 * 3}{2 + 3})$

$P = (\frac{-25}{5},\frac{25}{5})$

$P = (-5,5)$

MATH HELP!!!

AfilCa [17]

1220*24 = 29,280 per year

multiply that by number of years until he retires:

761280 / 29280 = 26 years

292800 / 29280 = 10 years

the other 2 arent even years so it should be one of those 2. I would say the larger number

Balance on statement = Actual amount in the account - Monthly fee - Overdraft protection fee - Check written + Amount transferred ............ (1)

Substituting all the relevant values into equation (1), we have:

Balance on statement = $256 - $8 - $33 - $312 + $250

Balance on statement = $153
