8y-2x=24
Solve for y
8y=2x+24
y=(1/4)x+3
So no it is in the form y=mx + c
m is the slope
So the slope is 1/4

Dear Madison,

I will be glad to offer you my services. In order to find the slope of an equation you must use the slope intercept formula. Here is the formula:

y=mx+b


Your equation is actually almost in slope form, however there is an 8 attached to the "y." When you have a number and a letter side by side it means that they are being multiplied. So for example:
"10C" actually means "10 multiplied by C"
If you are familiar with how equations work, then you can proceed from here. If not I will explain here. Equations are like see-saws, you want them to be balanced. So whatever you do to one side has to be done to the other. In order to balance them you have to do the opposite function of what you are trying to change. So if you are trying to get rid of a positive 8 you would subtract.
The Work to Solve Your Equation:
1. Here is the equation: 8y-2x=24
2. Divide 8y by 8 to leave y-2x on the left side of your equation.
3. Now remember whatever you do to one side has to be done to the other. So you must divide 24 by 8.
4. Now this is what you have: y-2x=3
5. The formula is "y=mx+b" so we now have to rearrange our numbers into that format. So we want to have the y by itself. In that case we would add a positive 2x in order to remove the "-2x".
6. y=2x+3
7. I sincerely hope that this explanation was useful.

If my friend and i went to get ice cream, I have $30 and each ice cream is $5. What equation would help me solve this? I need an

<h3>Hello there!</h3>

Your question asks to make an equation with the information that was given.

<h3>Answer: y = -5x + 30</h3>

In order to make an equation for your question. We would be making an equation with the formula: y = mx + b.

Formula: y = mx + b

m = change

x = amount of ice cream

b = starting value

We would need to gather the key information from the question.

Key information:

You have $30

Each ice cream cost $5

With the information above, we can make an equation for the question.

What we know is that you started with $30, so that means that 30 would be your b value (starting value).

Your equation should look like this:

y = mx + 30

Now, we know that each ice cream cost $5, but since we're paying for the ice cream, we would subtract that from our starting value. This means that our change would be -5, since we are taking away $5 each time we buy ice cream.

Your equation should look like this:

y = -5x + 30

The equation above would be the equation for your question.

We would do nothing to x but just leave it as is, since we don't know how many ice creams you're going to buy.

y = -5x + 30 should be your FINAL answer.

<h3>I hope this helps!</h3><h3>Best regards, MasterInvestor</h3>

Weights of cars passing over a bridge part 2<br>​
DaniilM [7]

Step-by-step explanation:

The solution to this problem is very much similar to your previous ones, already answered by Sqdancefan.

Given:

mean,  mu = 3550 lbs (hope I read the first five correctly, and it's not a six)

standard deviation, sigma = 870 lbs

weights are normally distributed, and assume large samples.

Probability to be estimated between W1=2800 and W2=4500 lbs.

Solution:

We calculate Z-scores for each of the limits in order to estimate probabilities from tables.

For W1 (lower limit),

Z1=(W1-mu)/sigma = (2800 - 3550)/870 = -.862069

From tables, P(Z<Z1) = 0.194325

For W2 (upper limit):

Z2=(W2-mu)/sigma = (4500-3550)/879 = 1.091954

From tables, P(Z<Z2) = 0.862573

Therefore probability that weight is between W1 and W2 is

P( W1 < W < W2 )

= P(Z1 < Z < Z2)

= P(Z<Z2) - P(Z<Z1)

= 0.862573 - 0.194325

= 0.668248

= 0.67 (to the hundredth)
