Answer:
29 and 17
Step-by-step explanation:
Sum: 29 + 17 = 46
Difference: 29 - 17 = 12
Y^2 -11y = 0
We can factor it:
y * (y -11) = 0
So y = 11, 0
Simple actually. The 1000 is the starting price the -20 is the losing of value per week and the w stands for the number of weeks.
answer
10
step-by-step explanation
the equation given is sin(x) = cos(y) with x = 2k + 3 and y = 6k + 7
substitute in 2k+ 3 for x in sin(x) and substitute in 6k + 7 for y in cos(y)
sin(x) = cos(y)
sin(2k + 3) = cos(6k + 7)
we know that sin(x) = cos(90 -x)
sin(2k + 3)
= cos(90 - (2k + 3) )
= cos(90 - 2k - 3)
= cos(87 - 2k)
substitute this into the equation sin(2k + 3) = cos(6k + 7)
sin(2k + 3) = cos(6k + 7)
cos(87 - 2k) = cos(6k + 7)
87 - 2k = 6k +7
80 = 8k
k = 10
