The answer is D because to find the slope of a line that is perpendicular to another, you have to find the opposite reciprocal. so here the slope would be -1/4. now, take that slope and put it into an equation. like the following:
now to find b you must insert the points into the equation (plug in 4 for x, and 15 for y).
b then equals 16. so, the answer is D.
30% = 0.3
Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.
Solution:
To write percent to decimal, divide the number by 100.
= 0.3
30% = 0.3
Average use of water each day = 90 gallons
= 27
Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.

Answer:
So far we have looked at linear systems of equations in which the lines always intersected in one, unique point. ... When we graph them, they are one line, coincident, meaning they have all points in common. This means that there are an infinite number of solutions to the system.
Step-by-step explanation:
Answer:
-20%
My brain is weird on how i figure it out but I divided 48 by 60 and got .80 so i just got the other whole to make it 1 so it is 20%. This is not the correct way to do this but this is how i got my answer.
