Use slopes and y-intercepts to determine if the lines 4x−3y=6 and y=43x−1 are parallel.

Answer:

Since they have the same slope, they are parallel.

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope. If two lines are parallel, they have the same slope.

4x−3y=6

Placing into the above format:

3y = 4x - 6

y = \frac{4x - 6}{3}

y = \frac{4x}{3} - 2

The slope m = \frac{4}{3}

y=4/3x−1

The slope is m = \frac{4}{3}

Since they have the same slope, they are parallel.

erastova [34]

If you set up a proportion, this will make sense.


\frac{6}{1}= \frac{12.5}{x}

Now, Cross Multiply


6x = 12.5

x = 25/12

Two-step equations with decimals and fractions<br><br> Solve for p.<br><br> −5(p+ 3/5 )=−4
GrogVix [38]

Answer:

1/5 or 0.2

Step-by-step explanation:

-5(p+3/5)=-4

Let's convert 3/5 to decimal form:

-5(p+0.6)=-4

Expand parentheses:

-5p-3=-4

Add -3 to both sides:

-5p=-1

Divide both sides by -5:

p=1/5 or 0.2

Hope this helps!

The number of vehicles passing through a bank drive -up line during each 15-minute period was recorded. The results are shown be
tangare [24]

Answer:

Step-by-step explanation:

I think the median you are asking is the middle value,

because there is a total of 20 vehicles,  there are two middle number: 31 and 31.

To solve this:

you first plus these two numbers together, you will get 62.

then divide them by 2, then you will get the middle number.

the middle number will be 31. ( actually because theese two number are the same, you do not really need to plus them then divide by 2, you could just answer the question 31, but because when you do other question and has the same situation but not the same number, (suppose you got 20 and 21) Then you need to do this question like I said above)

I wish this could help you.
