Answer: Part a: b represents the base fee charged for the "house call" job
m is the hourly rate.
x is the number of hours at the job.
y represents the total cost for the job.
Part b:. The y-intercept is 65
The equation follows y=mx+b
Y= 42x + 65
Part c:. $275
Step-by-step explanation:
The difference between the two total costs, (Camilla 191 - Connor 107)
= $84. That is the rise. The run is the difference in time, 2 hours. 84/2 = 42.
m= 42
42 from 107 to find b, the base fee, 65 This is the y-intercept.
The equation is y= 42x + 65
Quick check using Camilla's bill: 191 = (42)(3) + 65
191 = 126 + 65 True!
Part C:
To find the total cost of the plumber's 5 hour job,
Y = 42(5) + 65
Y= 210 + 65
Y= $275

Answer: z = -5/-3
Step-by-step explanation:
(3z−11)+(6−6z)
3z - 11 + 6 - 6z
- 6z + 3z - 11 + 6
- 3z - 5
z = -5/-3
Start off with: 5 1/6 - 1 5/9
turn it into an entire fraction: 31/6 - 14/9
make a common denominator (which is 18): 93/18 - 28/18 = 93 - 28 = 65/18
65/18 + 7 2/3 is the new equation
7 2/3 = 23/3
23/3 = 138/18
65/18 + 138/18 = 203/18
Simplify: 203/18 = 11 5/18
Answer: 11 5/18
