What is the slope of the line whose equation is -48 = 2x - 8y?<br> Enter your answer in the box.
aleksandr82 [10.1K]

Answer:

The slope is \frac{2}{8}

Step-by-step explanation:

Take the general equation of a straight line y = mx+c

Here m is the slope of the line.

So let's get the equation of the line in the question in the same form.

-48 = 2x-8y

Add 8y to both sides: 8y - 48 = 2x

Add 48 to both sides: 8y = 2x + 48

Divide by 8 to get it into the general equation: y = \frac{2}{8} x + 6

Now compare it to the general equation to find the value of m. The value of m is the coefficient of x which we can see is \frac{2}{8}

A bag contains 22 coins consisting of quarters and nickels. The total value of the coins is $3.90. How many nickels are in the b
bezimeni [28]

Answer:

8 Nickels

Step-by-step explanation:

Since a Nickel is worth 5 cents ($0.05)

And a Quarter is worth 25 ($0.25)

and theres 22 coins

8 of those coins would be nickels which would mean we add 8 nickels up

8 x 0.05 = 0.4

then we add the quarters up

14 x 0.25 = 3.5

3.5 + 0.4 = $3.90

$70.00 at 5% for 2 years
aleksandrvk [35]

Answer:

$7

Step-by-step explanation:

Hey there

to solve this kind of problem we use the formula:

<h3>\frac{p * t * r}{100} </h3><h3>if we solve it :</h3>

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 70 × 0.05 × 2 = 7

I = $ 7.00

The simple interest accumulated

on a principal of $ 70.00

at a rate of 5% per year

for 2 years is $ 7.00.

EleoNora [17]
Y = a(1 - r)^t
Y = 8,000(1 - 0.06)^t

You can see a = 8,000

Find the volume (show work)
Karo-lina-s [1.5K]

V = 1/3 × base × height

V = 1/3 × ( 8 × 8 ) × 7

V = 1/3 × 64 × 7

V = 448/3

V = 149.33333

V = 149.3
