Let x = hours of service.
Let y = total charges for x hours
The fixed charge is $20.
The charge per hour is $20.
Brock's charges for x hours is
y = 40 + 20x
This is a straight line with slope = 20 and y-intercept = 40.
The correct graph is W.
Answer: W
Answer: 258 yards
Step-by-step explanation:
Since Chad wants each balloon string to be 6 feet long, and Chad wants to get 43 balloons, the number of yards of string that he will need will be calculated by multiplying 43 by 6. This will be:
= 43 × 6
= 258 yards of string
Answer:
y = -3 m = -1 b = 3
Step-by-step explanation:
-3y=3x-9
To isolate the y variable, divide both sides by -3.
y = -1x + 3
y = -3
m = -1
b = 3
M(CXA) = m(BXA) + m(CXB)
= 30°20' + 40°35'
m(CXA) = 70°55'
