Answer:

(top line) y=4/5x + 0, (bottom line) y=4/5-0.32

Step-by-step explanation:

so take the equation y=mx+b

b is the y intercept, which is where the line crosses (0,b)

the m is the slope, which is rise/run.

If the lines are parallel, the slopes are the same, just different y intercept

Step-by-step explanation:

the usual equation for a line is

y = ax + b

a is the slope. it is always the factor of x and is expressed as ratio y/x. this indicates how many units y changes, when x changes a certain amount of units when moving from one point to another.

(0, -3.2) is one point. and (4, 0) is another.

x changes by +4 (from 0 to 4).

y changes by +3.2 (from -3.2 to 0)

the slope is therefore

3.2/4 = 32/10 / 4 = 32/40 = 4/5

b is the y-intercept. that is the point, where the line crosses the y-axis (the y value when x = 0).

the given point specifies this already.

so, the line equation of the lower line is

y = (4/5)x - 3.2 or (4/5)x - 32/10 or (4/5)x - 16/5

the upper line is parallel, so the slope is the same.

and what is b, the y-intercept ? we see that the line goes directly through the origin (0, 0). so, b = 0.

the line equation of the upper line is

y = (4/5)x

If you deposit $6000 into an account paying 8% annual interest compounded monthly, how much money will be in the account after 7

Leviafan [203]

Answer:

$10278

Step-by-step explanation:

Given data

P= $6000

R= 8%

T= 7 years

The compound interest formula is

A=P(1+r)^t

substitute

A=6000(1+0.08)^7

A=6000(1.08)^7

A=6000*1.713

A=$10278

Which function has the greatest rate of exponential growth?

Veronika [31]

Answer:

Step-by-step explanation:

Here, we want to find which of the expressions have the greatest rate of exponential growth.

The easiest way to go about this is have a substitution for the term t;

Let’s say t = 6

Thus;

h(t) = 1.18^1 = 1.18

K(t) = 0.375^6 = 0.002780914307

f(t) = 1.36^6 = 6.327518887936

g(t) = 0.86^6 = 0.404567235136

Another way to find this is to express each as a sum of 1

f(t) = (1+ 0.36)^t

g(t) = (1-0.14)^t

k(t) = (1-0.625)^t

We can see clearly that out of all the terms in the brackets asides 1, 0.36 is the biggest in value

What is 2 times 2/6?

Aloiza [94]

Hi there!

I can see why you've posted a question like this here - For adding, subtracting, multiplying, or dividing fractions by whole numbers can be difficult to come out with a precise answer, so let me make it look easier for you!

So, the steps are:

Smush the 2 (whole number) and the 2 (the numerator of the fraction) together on top so its (2)(2) over 6. I can show you what I mean, if you'd like.

$\frac{(2)(2)}{6}$ This is what it should look like.

Now, what is 2 times 2? You can use a calculator for this part.

$2 *2 = 4$

Now, we can get to the last part, my favorite one!

Simplify $\frac{4}{6}$ down to $\frac{2}{3}$ .

How did we do it? EASY!

See what number does evenly into both numerators and denominators. In this case, 2 goes into 4 twice, and 2 goes into 6 three times, so we're left with our beautiful answer $\frac{2}{3}$ .

That wasn't so bad, was it? You can use this as a guide for figuring out math problems like these, in case you're stuck again. But just in case, message me if you need anymore help! :D
