Answer:

y = (3/-2)x + 4.

Step-by-step explanation:

slope intercept form is y = mx + b

1. Lets first look for the y intercept (b). On the graph the line intercepts the y axis at 4. 4 is our b.

2. To find the slope (m) remember rise over run. Counting from lower dot, it goes up 3 and left 2. 3/-2. The two is negative because it is decreasing (towards the left of the graph).

3. Now plug the numbers into slope intercept form. y = (3/-2)x + 4.

Answer: m=−3

Step-by-step explanation: −40−2(3m+1/2)=7m−2

−40+(−2)(3m)+(−2)(1/2)=7m+−2

−40+−6m+−1=7m+−2

(−6m)+(−40+−1)=7m−2

−6m+−41=7m−2

−6m−41−7m=7m−2−7m

−13m−41+41=−2+41

−13m/−13=39/−13

m=−3

What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.

 

m = -3, hope it was helpful! :)

chris worked 3 1/2 hours at his uncles farm. He was paid 8$ for every 1/4 hour he worked. How much money did chris make

Answers

Answer:

$112

Step-by-step explanation:

So first figure out how much he makes an hour

8*4 is 32.

32*3 1/2 is $112

The amount that Chris will make will then be $112.

The first thing to do is to divide 3 1/2 by 1/4. This will be:

= 3 1/2 / 1/4

= 7/2 × 4/1

= 14

Now we'll then multiply 14 by $8. This will be:

= $8 × 14

= $112

The amount made will be $112.

x = - 35 / 5

x = -7, C

Problem 3:
