Answer:

A: -6.5

Step-by-step explanation:

Take two points that we already know are on the line and find the slope

I used:

(4, -10) and (7, -30)

X1 (first x coordinate): 4

Y1 (first y coordinate): -10

X2 (second x coordinate): 7

Y2 (second y coordinate): 30

These appear to be exactly on the graph at a certain point along the line. We can't choose a coordinate pair that isn't on the line at an exact point.

Use (Y2-Y1)/(X2-X1)

(-30-(-10))/(7-4) = (-30 + 10)/3 = -20/3 = approximately -6.67.

The closest answer to that is A.

A soccer team played 25 games last season. They won 16 games, lost 5 games, and tied the rest.
goldenfox [79]

Answer:

16% or 4/25

Step-by-step explanation:

16 + 5 = 21

25 - 21 = 4

4/25 = 16%

This is right because 21/25 is 84% and 84% + 16% = 100%

What’s the measure of angle c?<br><br><br> Some please answer fast. Please.
kow [346]

Answer: 42

Step-by-step explanation:

Ok what you want to do is add all of them up and equal it to 180 because a triangle is 180 degrees .

Your equation should look like this

9x-3+22x+1+42-3x = 180

What you want to do first is combine all the x and numbers on the left side so it should look like this

1) 28x+40= 180

Then you want to subtract 40 on both sides so it will look like this

2)28x=140

You want to get x by it self so you divide 28 on both sides

3) x=140/28

4) x=5

Since you are finding c you have to insert 5 into x

1) 9(5)-3

2)45-3

Then your answer should be 42

Savatey [412]
The answer would be ~30~ because 2*2^3 = 2^4= 16 then 3*6=18 then 16+18-4=30

Hope this helps

Have a great day/night
