Answer:
5 hours
Step-by-step explanation:
Electrician got 90 for the first hour from the total bill, thus we can say:
330 - 90 = 240 remaining for remaining hours
$60 per hour, so $240 for how many hours?? We divide:
240/60 = 4 hours
So, electrician works 4 hours for 60 per hour = 2 * 6 = 240
and 1 hour for 90 (first hour) = 1 * 90 = 90
Total Bill is 240 + 90 = 330 {exactly what we have}
So we have checked and back-worked our problem to get electrician's total hours of work:
1 + 4 = 5 hours
Answer:
2 × h
Step-by-step explanation:
h = b ÷ 2 (multiply both sides by 2)
2 × h = b ÷ 2 × 2
2 × h = b
b = 2 × h
Answer:
y = (-3f(x+4))+5
Step-by-step explanation:
Please see the picture below.
1. Apply to the function the vertical stretch with scale factor 3:
y = 3f(x)
2. Multiply the function by -1 to reflect it over the x-axis:
y = -3f(x)
3. Add up 4 units from x to translate the function 4 units to the left:
y = -3f(x+4)
4. Add up 5 units to the entire function to translate it up 5 units:
y = (-3f(x+4))+5
