Answer:
Ellen invested $60 and Bob invested $140
Step-by-step explanation:
let the two amounts invested by 3x and 7x
(notice 3x : 7x = 3 : 7 )
then 3x + 7x = 200
10x = 200
x = 20
then 3x = 3(20) = 60
and 7x = 7(20) = 140
60+140=200
The answer is 9. 7 times 9 is 63 and then 63 divided by 3 is 9.

Answer:
Step-by-step explanation:
The question is incomplete, as the graphs or equations of the lines are not given.
However, I will give a general explanation of calculating both intercepts
A linear equation is of the form:
Where:
y intercept
So, the equation
has 2 as its y-intercept
Set y to 0, to calculate the x-intercept
Collect like terms
Multiply by 3/2
So, the equation with the required criteria is:
