Answer:
2.5 hours
Step-by-step explanation:
If u times 5.50 x 2.5 = 13.75
So 2.5 hours is basically 2h 30min
Answer:
y = 0.28571428571429x – 2.4285714285714
or
y =
2 x
7
– 17
7
When x=0, y = -2.4285714285714
When y=0, x = 8.5
Step-by-step explanation:
Answer:
y=1/2x-5
Step-by-step explanation:
We have slope so we just need to find the y intercept.
slope intercept formula is
y=mx+b
(m) is slope
(b) is y int
y=1/2x+b
now apply our given x and y values (4 & -3)
-3=1/2(4)+b
simplify
-3=2+b
subtract 2 from each side
-5=b
put that into our equation
y=1/2x-5
a=180-117=63
b=180-81-63=36
so angle a is 63, and angle b is 36
