Answer:
y=6/5x+13
Step-by-step explanation:
6y=-5x+16
Divide by 6
y=-5/6x + 8/3
Slope: 6/5 (opposite reciprocal)
7=-5(6/5)+b
7=-6+b
b=13
Answer:
10 hours
Step-by-step explanation:
More time will be required to cover a greater distance given that the speed is constant.
Speed required to drive 520 miles will be ,

= 10 hours
For this case, the first thing we are going to do is define the following variable:
x = unknown number
We now write the following inequality:
5-3x <= 11
We clear x:
5-11 <= 3x
-6 <= 3x
-6/3 <= x
-2 <= x
The solution set is:
[-2, inf)
Answer:
the solution set is:
[-2, inf)
