Answer:

A. $\frac{3}{7}$

Step-by-step explanation:

The given equation is

$3x-7y=14$

We solve for y by subtracting 3x from both sides to obtain;

$-7y=14-3x$

We now divide through by -7 to get;

$y=\frac{-3}{-7}x+\frac{14}{-7}$

This simplifies to;

$y=\frac{3}{7}x-2$

This equation is now in the form y=mx +c, where $m=\frac{3}{7}$ is the slope.

On a certain exam, Tony corrected 20 papers and found the mean for his group to be 70. Alice corrected the remaining 10 papers

son4ous [18]

Answer:

The mean of the combined group is 76.67 ≈ 77

Step-by-step explanation:

The sum of the grades in Tom's group is 20×70 = 1400
The sum of grades in Alice's group is 10×90=900
The sum of gradees in the combined group is =1400+900=2300
Then the mean grade of the combined group is $\frac{2300}{30}=76.67$

where

2300 is the sum of the all grades in the combined group
30 is the total number of people in the group

o-na [289]

A basket contains 12 apples and some other fruit
40% of the total fruit are apples...so 40% of the total fruit is 12..

0.40x = 12....with x being the total fruit in the basket <== ur equation
x = 12 / 0.40
x = 30....and u have 30 pieces of fruit in the basket

What is the slope of (2,12) (4,20)

Ugo [173]

This is the formula for slope between two points:

$\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$y_{2} =20\\y_{1} =12\\x_{2} =4\\x_{1}=2$

so...

$\frac{20-12}{4-2}$

$\frac{8}{2}$

4

The slope is 4

Hope this helped!
