How to find Slope on a graph?

Mathematics
1 answer:
UNO [17]2 years ago
8 0

Answer:

there are several ways to write, and find slope...see explanation

Step-by-step explanation:

Way 1: slope Intercept- y=mx+b

step 1: find where the line crosses the Y axis(the one running up and down...thats is your "b" so if the line crosses at -2...it would be this:    y=mx-2

Step 2:from the point where the line crosses the Y axis, count how many up/down and Left/right to the next point..so if you go up 2 right 1, it would look like this y=2x-2

Up=positive

down=negative

left=negative

right=positive

You have $5600. The best interest rate you can find is 3%
EleoNora [17]

Answer:

18 years

Step-by-step explanation:

The formula for computing accrued amount A for a principal of P at an interest rate of r(in decimal) compounded n times in a year for t years is given by

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

Note that r is percentage converted to decimal. So 3% = 3/100 = 0.03

We can rearrange the above equation to:

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

Taking logs on both sides

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

This gives

log(\frac{A}{P}) =nt \times log(1 + \frac{r}{n})\\So,\\nt = \frac{log(\frac{A}{P})}{ log(1 + \frac{r}{n})}

In this particular problem, n = 4, , A= 9600, P = 5600, r =0.03, so r/n = 0.03/4 = 0.0075

1 + r/n = 1+0.0075 = 1.0075

4t = log(9600/5600)/log(1.0075) = log(1.714) / log(1.0075) = 0.234 /0.00325 = 72

t = 72/4 = 18 years

HELP ME: A camera usually sells for $68. Because it was slightly damaged, it sold for $59.90, what was the rate of the discount
soldier1979 [14.2K]
12%
$68 - 59.9 = $8.1
$8.1/$68 = 0.11911764705
0.11911764705 x100 = 11.911764705
11.911764705 is rounded up to 12

Please help guys ♡♡♡♡♡♡​
Oksanka [162]

Answer:

I'm pretty sure the Y position of the eyes is 70.

If the Variable Y is equal to 70, and the Y variable is where the Y axis value goes. Then the Y position of the eyes is equal to the Y variable which is 70. I think that makes sense, but feel free to comment if it does not so that I can help you figure it out.

PLEASEE HELPP ME IM DESPERATE​
miss Akunina [59]

Answer:

I can help with Q "4" as -

It uses triangle congruence test -  here we use - SAS, as

one side is equal as it is given

both the  angles are 90 degree

and they share a same side

so -

8x = 6x + 5

8x - 6x = 5

2x = 5

x = 2.5

RU = 6x+ 5 = 6 (2.5) + 5 = 20

( I am not so sure but I think this is the answer )
