If 100 students make up 40% of the 6th grade population, then 50 students make up 20% of the 6th grade population. 20% × 5 makes 100% so if your multiply 50 by 5 you'd get your population.
50 × 5 = 250 sixth-graders

Answer:

250

Step-by-step explanation:

You can solve this by cross-multiplication.

If one hundred sixth-grade students represent 40% of the total, you need to find the 100% so, multiply 100% by 100 students and then divide by 40% and you'll have the total sixth-grade students.

40%----100

100%--x=

X=(100*100)/40\\X=250

What is the slope of a line that contains the points (8-,4) and (10,-2)
erastova [34]
m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{-2 - (-4)}{10 - 8} = \frac{-2 + 4}{2} = \frac{2}{2} = 1

   y - y₁ = m(x - x₁)
y - (-4) = 1(x - 8)
   y + 4 = 1(x) - 1(8)
   y + 4 = x - 8
       - 4       - 4
         y = x - 12

Grade 11 Algebra 2

Answer:

y=-3/2x-2

Step-by-step explanation:

simplify 3x+2y=6 first

-3x. -3x

2y= -3x+6

Divide by 2

y= -3/2x+3

since it's parallel you would use the same slope

slope= -3/2x

Now you need to find b (x-intercept)

point (-2,1)=(x,y) use this to plug into y=mx+b

=

(1)=-3/2(-2)+b (simplify)

1 = 3+b

-3 -3

-2= b

so put it together and get

y=-3/2x-2
