Answer:
y = 9/10x - 7/5
Step-by-step explanation:
Slope = 9/10
Point (6,4)
y-intercept = 4 - (9/10)(6) = 4 - 54/10
= - 7/5
Answer:
x = 11, y = 9
Step-by-step explanation:
Given the 2 equations
x + y = 20 → (1)
3x - 3 = 30 → (2)
In (2) add 3 to both sides
3x = 33 ( divide both sides by 3 )
x = 11
Substitute x = 11 into (1)
11 + y = 20 ( subtract 11 from both sides )
y = 9
We translate Grayson's charges through the following mathematical expression : 35 h + 35 where h is the number of hours while that of Ian is 45h + 15. The number of hours where the charges are equal is 35h + 35 = 45h + 15; h = 2 hrs. Hence the number of hours minimum must be above 2 hours.
I think the answer to that is A
