what is the slope of a line parallel to the line whose equation is y=2/3x+7 fully simplify your answer

Mathematics

Answer:

2/3

Step-by-step explanation:

When a line is parallel to another, it means that there are never going to be any solutions(they won't ever intersect each other.) To do so, the slope of the lines have to be the same. It doesn't matter what the y-intercept is.

So the slope of the second line is going to be the same as the first line: 2/3

mixer [17]

Answer:

d = 56x + 412

Step-by-step explanation:

To find the total number of miles traveled on Monday and Tuesday, use a linear equation to write the function.

y = mx+b where m is the speed or rate of change and b is the starting point.

The starting point on Tuesday is 412 miles. This is b.

The number of miles traveled on Tuesday is found by calculating 56 miles times the number of hours traveled.  This is the slope or m.

So the equation is d = 56h + 412.

Please help!! I’m not sure how to answer this question!!

<h3>Answer:  9V</h3>

=============================================================

Reason:

The volume expression of a cone with radius r and height h is

\frac{1}{3}\pi*r^2*h

Let's plug in the given height h = 12 and we'd get

\frac{1}{3}\pi*r^2*h\\\\\frac{1}{3}\pi*r^2*12\\\\\left(\frac{1}{3}*12\right)\pi*r^2\\\\4\pi*r^2\\\\

This is the volume of the first cone. We're told the first cone has a volume of V, so we can say V = 4\pi r^2

We can't find the actual numeric volume because we don't know what value replaces r. So we leave it as is.

The second cone has the same height (h = 12) but the radius is now 3 times in size. Instead of r, we use 3r

Replace every copy of r with 3r. Then simplify

4\pi*r^2\\\\4\pi*(3r)^2\\\\4\pi*9r^2\\\\9(4\pi r^2)\\\\9V\\\\

The radius tripled which results in a volume that's 9 times bigger.

I really need help on this please can someone help me thanks in advance

Answer: option 2 is the better option

Step-by-step explanation: well in this case as you are trying to find the individual prices of the candy bars, you would divide the total price by the amount of candy bars. So in this case for the first problem, you would take the total price: $6.75 and divide it by 10. The answer to this would be .675 but you would round it up to .68 so that you have a two digit decimal. Therefore the answer is .68 cents for each candy bar.

you would repeat this process for the second problem. Total price: $7.25 divided by 12 (candy bars). The answer in this problem would then be .60 cents per candy bar. Once we see how much each would be, it is just a matter of seeing which price is higher. In this case, the second option is the better option.

Sorry this was long, that's how i explain things, but i hope this helps
