Answer:
slope = -4/5
y intercept = -4
Step-by-step explanation:
-5y = 4x+20
divide each side by -5
y = 4x/-5 + 20/-5
y = -4/5 x -4
it is in the form y = mx +b where m is the slope and b is the y intercept
m = -4/5 and b = -4

Answer:
Mean: 12
Median: 11
Step-by-step explanation:
For the median you would put the numbers in order from least to greatest (5, 5, 6, 7, 10, 12, 17, 18, 20, 20) then find the middle. But in this case, since there is two in the middle, you add them and divide that number by 2.
For the mean, you add all of the numbers up together to get 120. Then divide by the amount of numbers there are, which is 10, to get 12.
Answer:
Step-by-step explanation:
Given : Jordan is paid $12 per hour for mowing lawns and $14 per hour for planting gardens.
Let m represents the number of hours mowing lawns and g represents the number of hours planting gardens.
He can work a maximum of 40 hours per week, and would like to earn at least $250 this week.
Then, the system of the inequality becomes
Hence, the system of inequalities could be used to represent the given conditions :
Answer:
True
Step-by-step explanation:
A linear pair occurs when two angles are together on a line, forming the angle on the side of a line. Assuming this, we can find out that the angle formed by one side of a line is 180. Hence, a linear pair will always form an 180 degree angle.
