Answer:
1. line a and c and parallel. line b is perpendicular with line a and c. 2. line b and c and parallel. line a is perpendicular to lines b and c. 3. y= -3x + 3 4. y=(5/3)x - 9
Step-by-step explanation:
To find parallel and perpendicular, make the slope opposite and find b by plugging in the points. Parallel is the same slope.
Answer:
n= 3
Step-by-step explanation:
3 (4 + n) = n + 18
you take 3x4=12
then 3x3=9 then you add 12 and 9 which would be in the ( )
12+9 = 21
then if you replace n =3 on other side and add it to 18 answer is 21
therefore both sides would equal 21 so n=3
3(4+3)=3+18
21=21
Answer:
Mark me as Brainliest

Step-by-step explanation:
To find the inverse of a function, just “trade” x and y and solve for the “new” y. The graph of the inverse is the reflection of the original function over the line y=x.
Rewrite the function

as the equation, y=x+3
Trade x and y.
X=y+3
The symbol for the inverse if 

90 ft is less than 32 yards
