Answer:
8 dollars per hour
Step-by-step explanation:
You make 92 a week
20 of that is from your allowance
92-20 = 72
72 is from your part time job
You work for 3 hours on Friday and 6 hours on Saturday, for a total of 3+6 = 9 hours
Take the amount of money earned and divide by the number of hours to determine the money earned per hour
72/9 = 8 dollars per hour
You can represent this problem by using the multiplication problem 5x4
The standard form for this parabola is x = a(y-k)^2 + h because this is a sideways-opening parabola. Our h and k values for the vertex are (-4, -1). And it goes through (2,0). We just need to solve for the a. Filling in accordingly, 2 = a(0+1)^2-4 so 2 = a - 4. a = 6. A above.
correct answer is 6!
You have to get "X" by itself so you subtract 12, 7-12 is -5 so "X" = - 5
