Answer:

$1000 ; 500 ; 1000 ; y = 500x + 1000

Step-by-step explanation:

From the graph, the initial deposit which started the savings account is $1000 ; this is the value on the y - intercept, the value in the account at time or period = 0.

The slope :

x1 = 0 ; y1 = 1000

x2 = 6 ; y2 = 4000

Slope = Rise / Run

Rise = y2 - y1 = 4000 - 1000 = 3000

Run = x2 - x1 = 6 - 0 = 6

Hence,

Slope = 3000 / 6

Slope = 500

y - intercept = 1000 (from. Graph)

Equation in slope intercept form:

General form : y = mx + c

m = slope ; c = intercept

Equation is written as ;

y = 500x + 1000

Can you please help me with#11?I'm not sure how to find the answer.​
almond37 [142]

Answer:

You need to find the x and y intercepts so...

The x intercept is (18,0) since x=18

The y intercept is (0,12) since y=12

Step-by-step explanation:

Cover the y when you are finding the y intercept

Cover the x when you are finding the x intercept

8x/8

144/8

=18

12y/12

144/112

=12

Is 26,341 divisible by 3?
shepuryov [24]

No.  26,341 is not evenly divisible by 3 .

Here's the trick you can use to decide this
just by looking at a big number:

==>               If a number is divisible by 3, then the
                     sum of its digits is divisible by 3.

I've never taken the trouble to figure out why this works,
but it does work.  I didn't make it up.  It's widely known.

So let's look at  26,341 .

The sum of the digits is  (2 + 6 + 3 + 4 + 1)  =  16 .

16  is not divisible by  3 , so  26,341  is not divisible by  3 .

Is that cool or what !
