To find the inverse interchange the variables and solve for y
I did this in my head but the answer is $36 45/5 is 9 9*4 is 36. And if you add another it totals to 45. Thus the answer is $36.
Answer:
(1, 8 )
Step-by-step explanation:
A translation of 2 units left means subtracting 2 from the x- coordinate
A translation of 4 units up means adding 4 to the y- coordinate
Z (3, 4 ) → Z' (3 - 2, 4 + 4 ) → Z' (1, 8 )
Answer:
3:40 pm
Step-by-step explanation:
120 is 2 hours and 100 is 1 and 40 minutes
Givens
The numbers are n and n + 1
Average = Av = 105
Equation
Av = (n)(n + 1)/2
Solution
Av = 105
n(n +1)/2 = 105 Multiply both sides by 2
n(n + 1) = 105 * 2
n(n + 1) = 210 Remove the brackets.
n^2 + n = 210 Subtract 210 from both sides
n^2 + n - 210 = 0
factor
(n+15)(n - 14)
n + 15 = 0
n = - 15
n = - 15 which is the smallest of the two answers.
n + 1 = - 14
