Four ! 15 !and show work

1) 0.2 (m - 8) = 0.3m + 5 - 3 + 0.3m

2) 3/2x - 2.2 = 2 (0.7x - 1)

3) 0.2 (2x + 1/2) = 5 [ 0.5 + (-2) ]

4) a line contains the points (5,3) and (0, -1). what is the equation of the line?

1. m=-4.5

2. See steps below

3. See steps below

4.

Step-by-step explanation:

1. To simplify equations, distribute terms into the parenthesis by multiplying each term. Then combine like terms and solve using inverse operations.

0.2(m-8) = 0.3m+5-3+0.3m

0.2m - 1.6 = 0.3m + 5 -3 + 0.3m

0.2m - 1.6 = 0.6m + 2

0.2m = 0.6m + 1.8

-0,4m = 1.8

m= -4.5

Apply these same steps to questions 2 and 3.

4. To write the equation of a line, find the slope using the slope formula. Then substitute the slope and a point into the point slope form.

you need to show the graph

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
