Y = 2x + 9

2 is the slope which is rise over run or y2 - y1 over x2 - x1

9 Is the y intercept

Answer:

y = -2x + 9

Step-by-step explanation:

So we know that the line is going down, so that means that slope will be negative. Additionally we know that the y-intercept is 9 because that's where the line crosses the y-axis.

To find slope based on the graph, you can start from the left most point and do rise/run until you get to the next point. In this case, you'd start from (0,9) go down 2 units and over to the right 1, so your Slope is -2/1 or just -2.

So it would be written as y = -2x + 9.

Hope this helps :)

How to find compound rate from given values, 10 years after, and initial

dybincka [34]

The formula that calculates the compound rate from the given values is $r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

<h3>How to determine the compound interest rate?</h3>

The compound interest formula is:

$I = P(1 + \frac rn)^{nt} - P$

Where:

P represents the principal amount
r represents the compound interest rate
n represents the number of times the interest is compounded
t represents the time in years
I represents the interest

We start by adding P to both sides

$P + I = P(1 + \frac rn)^{nt}$

Divide through by P

$\frac{P + I}{P} = (1 + \frac rn)^{nt}$

Take the nt-th root of both sides

$\sqrt[nt]{\frac{P + I}{P}} = 1 + \frac rn$

Subtract 1 from both sides

$-1 + \sqrt[nt]{\frac{P + I}{P}} = \frac rn$

Multiply through by n

$r = n(-1 + \sqrt[nt]{\frac{P + I}{P}})$

In this case, t = 10

So, we have:

$r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

Hence, the formula that calculates the compound rate is $r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

In six years, clem kadiddlehopper will be five time as old he was 26 years ago. how old is he now?

levacccp [35]

Answer:

he is currently 34

Step-by-step explanation:

x + 6 = 5(x-26)

x + 6 = 5x - 130

+130 +130

x + 136 = 5x

-x -x

136 = 4x

/4 /4

x = 34

You can check your work as well:

34 + 6 = 40

34 - 26 = 8

8 x 5 = 40
