Answer:
In 14 weeks, they will have the same earnings.
Step-by-step explanation:
y = 55x + 1300 -------- (1)
y = 25x + 1720 -------- (2)
(2) = (1)
55x + 1300 = 25x +1720
55x - 25x = 1720 - 1300
30x = 420
30x ÷ 30 = 420 ÷ 30
x = 14
Answer:2:3
Step-by-step explanation:
becuase every 3 cup of flour you will need 2 cup of chocolate chip
The function is: f ( x ) = - x² + 60 x - 116 is in the form: f ( x ) = a x² + b x + c
Part A:
x = -b / 2 a = - 60 / ( - 2 ) = 30
Then we will charge it into the function:
f ( 30 ) = - 30² + 60 · 30 - 116 = - 900 +1,800 - 116 = 784
The vertex is ( 30, 784 ).
It means that the maximum profit is $784, when 30 windshields are repaired.
Part B:
x 1/2 = ( -60 +/- √(3600 - 464 )/ (- 2 ) = ( -60 +/- 56 ) / ( - 2 )
x 1 = 2, x 2 = 58
It means that a shop has to repair at least 2 windshields and not more than 58 windshields for making a profit.
Given the numbers on the computer 123 is shown very complicated. Well it’s not given all the numbers and mind thinking if u add formula 1 that shows that I have no idea what to tell you and ur stuck
