Yes the first one is a function. The second one with the arrows is not.
20% equals 4
80% divided by 20% is 4
4x4=16
he has 16 laps left
a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
Step-by-step explanation:
Given,
Price of one adult ticket = a = $25
Price of one youth ticket = y = $12.50
Maximum people that can be hold by theater = 1000
Therefore;
The maximum number of people can be 1000 or less than that.

As they want to revenue to be more than 15,000 therefore,

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.

rectangles
Step-by-step explanation:
Answer:
the slope is -8/5
Step-by-step explanation:
we need to get the equation in the form
y= mx+b where m is the slope and b is the y intercept
8x + 5y =40
subtract 8x from each side
8x-8x + 5y = -8x +40
5y = -8x+40
divide each side by 5
5y/5 = -8x /5 + 40/5
y = -8/5 x +8
the slope is -8/5 and the y intercept is 8
