The correct answer is A. EH.
Answer:
Slope = 40
Step-by-step explanation:
Time spent = 70 hours(given)
Fixed charge = $75 (given)
x = Total number of hours (given)
Variable charge = $40 * Total number of hours.
Variable charge = $40x
Fee charged, y = Variable charge + Fixed charge
y = 40x + 75 ($)
The equation of a straight line is given as: y = mx + c
where m = slope
Comparing it with the equation above, m = 40
Answer: 18
Step-by-step explanation:
Answer:
No solution
Step-by-step explanation:
So your equation would be x+3 times x+2 = 30
When you factor this out, you get x^2 + 5x + 6 = 30
Then you have to move the 30 over so you can set it equal to zero, so subtract 30 from both sides of the equal sign.
You now have X^2 + 5x -24 =0
Here you'd try to refactor, but unfortunately that doesn't work in this equation so you have to use the quadratic formula.
Look up the formula if you don't know it, it would be more confusing if I tried to type it out. Just keep in mind that for this equation, a=1 b=5 and c= -24.
