Solve for the indicated variable in each literal equation: a/b=c for b

How to find slope of any given line segment?

aniked [119]

Best Answer: I'll make one up and explain how to do it.

Lets say your two points are (2,6) and (-4,7)

To start with you need to use the point-slope formula which is y2-y1/x2-x1

Remember (x,y), Thus we have

7-6/-4-2 = 1/-6; So out slope is -1/6

Now lets use the following equation y = mx+b to solve for b which is the y-intercept. By substitution of either order pair we can solve for b

6 = 2(-1/6)+b; distribute the 2
6 = -2/6+b; add 2/6 to each side to isolate b
6+2/6 = b; put 6 over 1
6/1+2/6 = b; get a common denominator between 6/1 and 2/6 which is 6
6(6/1)+2/6 = b ; distribute
36/6+2/6 = b; add these up
38/6 = b; reduce to lowest terms by dividing by 2 to each
19/3 = b

So our final equation is y = -1/6x+19/3

1) A population of genetically modified

TiliK225 [7]

This is a linear equation or y=mx+c. Where y is the number of mosquitos at a particular month and x is the number of months. We know the initial population of the mosquitoes is c=20. They population doubles every month so this is the gradient, m=2. Therefore the equation for the growth of the mosquito population is:
y = 2x + 20.

So after x= 10 months the mosquito population will be,
y=2(10)+20= 40.

There will be 40 mosquitoes after ten months.

I really need help tyy

emmainna [20.7K]

Find the greatest common factor (gcf) in each grade between the girls and boys
in 6th grade the gcf is 8
64/8=8 72/8=9
the largest number of groups that can be made equally would be 8 groups of 8 girls and 8 boys
Hope this helps!!
