Answer:
tanx = 1
Step-by-step explanation:
I assume you mean sinx = cosx
In this case we have to recognize that tanx = sinx / cosx
So if we divide cosx over we can get tanx
So:
Cosx divided by itself gives us 1
sinx / cosx = 1
tanx = 1

Answer:
(8, - 5 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 4 → (1)
- x - 3y = 7 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the x- term.
- 3x - 9y = 21 → (3)
Add (1) and (3) term by term to eliminate x, that is
0 - 5y = 25
- 5y = 25 ( divide both sides by - 5 )
y = - 5
Substitute y = - 5 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(- 5) = 4
3x - 20 = 4 ( add 20 to both sides )
3x = 24 ( divide both sides by 3 )
x = 8
solution is (8, - 5 )
Monthly:
There are 12 months in a year. So, all we have to do is divide his yearly salary by 12.
57,852÷12
4,821
So, Jeremy's monthly salary is $4,821.
Weekly:
There are about 52 weeks in a year. So, we need to divide his yearly salary by 52.
57,852÷52
1,112.54
So, Jeremy's weekly salary is $1,112.54.
