Complete Question
On a two week job, a repairman works a total of 70 hours. He charges $75 plus $40 per hour. An equation shows the relationship where x is the number of hours and y is the total fee. Write the equation. What is the slope and y-intercept?
Answer:
a)Write the equation.
y = 40x + 75
b) What is the slope and y-intercept?
The slope = 40
y - Intercept = 75
Step-by-step explanation:
On a two week job a repairman works a total of 70 hours. He charges 75$ plus 40$ per hour.
The equation shows this realationship where x is the number of hours and y is the total fee is given using the equation of a straight line which is given as:
y = mx + c
Where m = Slope
c = y intercept
Applying this equation to our question , we have:
y= 40x + 75
The slope = m = 40
y-intercept = c = 75
Answer:
The possible values of v are 6 and -6
Step-by-step explanation:
The opposite operation of an absolute value is to add a ± to the other side, so when we solve for v we get
|v|=6
v=±6
Which is the same as
v=-6 and 6
Answer:
d + c = 12
d = 2c - 3
Step-by-step explanation:
Given that :
Total number of dogs and cats = 12
Let :
Dogs = d ; Cats = c
d + c = 12
Number of dogs = 2 times the number of cats less than 3 ;
Mathematically,
d = 2c - 3
Answer:
1. y = -0.6x + 5.4.
2. The entered points belong to a vertical line. There is no slope.
Equation: x = 6
