Answer:

4 students

Step-by-step explanation:

what we know: 12 students, 2/3 are wearing blue, 1/6 are wearing red

first you have to make the fractions have the same denominator<em><u>(2/3=4/6)</u></em>

theres also 1/6 that are not wearing blue or red <u><em>(1/6+4/6=5/6, 6/6-5/6=1/6)</em></u>

so that makes it 2/6 of the students not wearing blue<em><u>(1/6+1/6=2/6)</u></em>

simplify<u><em>(2/6=1/3)</em></u>

1/3 of 12 is 4<u><em> (12÷3=4)</em></u>

the equations are in parentheses and bolded, italicized, underlined.

hope this helps :)

A line that passes through the points (−5, 7) (10, 1). Using the mx+b format
lianna [129]

Answer:

y=2x-19

Step-by-step explanation:

I'm guessing you mean slope intercept form y=mx+b

If so, first you would have to find the slope of the line

To do that, use the formula y2-y1/x2-x1

Remember you can pick any coordinate pair for this

I will pick 1=y2 -5=y1 10=x2 and 7=x1

When I put that in the equation I get 1-(-5)/10-7

Overall I get 6/3, or 2

Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)

I will pick (10,1)

1=y and 10=x and 2=m

1=2(10)+b

this simplifies to 1=20+b

now subtract 20 from both sides and get -19 = b

Now you have your equation y=2x-19
