What is the slope of the line through the points (-3,3) and (6,-8)

STatiana [176]

Answer:

$\displaystyle \frac{-11}{9}$

Step-by-step explanation:

We will use the equation of change in y over change in x to solve for the slope of the line. Then, we will simplify.

$\displaystyle \frac{y_{2}-y_1 }{x_2-x_1}$

$\displaystyle \frac{-8-3}{6--3}$

$\displaystyle \frac{-8-3}{6+3}$

$\displaystyle \frac{-11}{9}$

Answer: 3900 $\pi$ ft^3

if you use the formula on how to find the volume of a cone

V= $\pi$ r^2*h/3

you will insert 30 where the r is, 13 in where h is, after you just solve that and your answer would be 3900 $\pi$ ft^3

Mandy is selling pancakes and waffles at her diner. On Monday she sold a total of 300 pancakes and waffles. If she charges $3 pe

Answer:

Mandy sold 250 pancakes and 50 waffles.

Step-by-step explanation:

From the information given, you can say that the sum of pancakes and waffles is equal to 300:

x+y=300

Also, the statement indicates that she charges $3 per pancake, $1 per waffle, and made a total of $800 and you can express this as:

3x+y=800

You have the following equations:

x+y=300 (1)

3x+y=800 (2), where:

x is the number of pancakes she sold

y is the number of waffles she sold

Now, you can solve for x in (1):

x=300-y (3)

Then, you can replace (3) in (2):

3(300-y)+y=800

900-3y+y=800

900-800=2y

100=2y

y=100/2

y=50

Finally, you can replace the value of y in (3) to find x:

x=300-50

x=250

According to this, the answer is that Mandy sold 250 pancakes and 50 waffles.

Tory is solving the equation shown correctly in her notebook, but the paper gets smudged, and she cannot read the last few lines

elena55 [62]

This question is incomplete because the options are missing. Here are the options:

A. - 4 = 5x

B. -4 = x

C. -4 + x = 0

D. -4 + 5x = 0

The correct next line of the solution is A. -4 = 5x

An equation is:

A mathematical expression that represents mathematical equality between two expressions.

It has two expressions and is separated by the equal sign, called members.

It has known elements and unknown or unknown data represented with letters like x

According to the above, it can be inferred that the correct answer is option A. because it expresses the correct values according to the operations that have been carried out in the previous lines.
