Write an equation in slope intercept form (-5,19) and (5,13) i got undefined but big ideas math won't let me type that how to i put in my answer?

Answers

Answer 1
Answer:

The slope-intercept form is

y = 16 - (3)/(5) x

How you submit that in your onlie env. you have to figure out using the help of that system.

Take the general slope intercept form y = mx + b and fill in both coordinates:

19 = -5m + b


13 = 5m + b

If you add them, you get a new equation with only b:

32 = 2b, so b = 16

Next, you find m, for instance by putting b back into the 2nd formula:

13 = 5m + 16

-3 = 5m

m = -3/5

Now you have found b and m to have the slope-intercept form:

y = 16 - (3)/(5) x

42% = 210 so, 
42/100=210/x
Cross multiply-
42x=21000
Divide by 42 on both sides and you get- 500

Answer:

500 Total people were surveyed

Step-by-step explanation:

All you gotta do is divide the number of football players, 210, by the percentage, 0.42. And when you divide 210 by 0.42, you get the total number of people surveyed, which was 500.

210 ÷ 0.42 = 500

Chelsea has 11 times as many art brushes as Monique. If they have 60 art brushes altogether, how many brushes does Chelsea have?

Answers

Let Monique's number of art brushes be m.
Then, since Chelsea has 11 times as many art brushes as Monique, Chelsea has 11m brushes.

Together they have 60 art brushes, so we write the equation:

                                              m+11m=60.

This means that 12m=60, dividing both sides of the equation by 12 we get m=5.

Chelsea has 11m=11*5=55 brushes.

Answer: 55
