28,000+3,000x=36,000+2,000x
X will be the number of years worked, now we just have to make the equation true.
I did the work out already, and the answer is 8!
If you want to check my answer just substitute it in to the problem for x.
Answer:
D
Step-by-step explanation:
Answer:
B = (A - 6) / 10
Step-by-step explanation:
This problem has 2 variables and 1 equation so it is not trivial to solve with confidence the value of B; however, we can solve for B in terms of A. With that being said, let's start.
If A divided by B = 10:
A/B = 10
10 remainder of 6
Could also be written as 10 & 6/B since B is the divisor. Rewrite this, you can get the equation:
A/B = (10B + 6) / B
A = 10B + 6
A - 6 = 10B
B = (A - 6) / 10
Thus, you have solve B in terms of A.
Cheers.
Answer:
{-π/2, π/2}
Step-by-step explanation:
Rewrite this as:
7sin^2 x - 14sin x + 7 = 0. Reduce this result by dividing all terms by 7:
sin^2 x - 2sin x + 1
Temporarily replace "sin x" with y:
y^2 - 2y + 1 = 0
Solve this through factoring: (y - 1)^2 = 0, or y - 1 = ± 0, or y = ±1
Recalling that y = sin x, we write
sin x = ±1, whose solutions are sin x = 1 and sin x = -1
The solution of sin x = 1 is π/2 and that of sin x = -1 is -π/2
and so the solution set is {-π/2, π/2}
