Answer:
Yes
Step-by-step explanation:
Unless the line is vertical, the graph of any straight line is the graph of a function.
___
A vertical line does not map x to one single y-value, so it does not represent a function. Any other line does map each x to a single y-value, so does represent a function.
5/90 have the common factor of 5, so what you do is
5/5 = 1
90/5 = 18
Therefore the simplified fraction is 1/18
The little rectangle in the top right means the angle is a right angle which equals 90 degrees.
This also means all the other angles are also 90 degrees.
Solve for x:
2x+8 = 90
Subtract 8 from both sides:
2x = 82
Divide both sides by 2:
x = 82/2
x = 41
Answer:
the answer is c
Step-by-step explanation:
5/8-3/8 is 1/4 + 2 is 2 1/4 then put into improper fraction
Answer:
x = -4, y = 3/2
Step-by-step explanation:
simplify the 1st equation by dividing each term by 4 to get:
x + 2y = -1
-5x + 2y = 23
Subtract to get: 6x = -24
x = -4
find 'y': 2y - 5(-4) = 23
2y + 20 = 23
2y = 3
y = 3/2
