Find the ratio of a to b if a= (5c) and b= 10(2c)

1:4

Step-by-step explanation:

5c: 10(2c)

5c: 20c

*you can cut out the C as there is also a c at the back*

5:20

divide 20 and 5 by 5

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

both graphs increase on their domain

neither graph has a y-intercept
