8.50x+60
that's what I have because you didn't say what the number of hours she worked.
Answer:
Parallel lines have the same slope, so you know the equation will be y = 2x + b. Use the point (1,5) to sub in for (x,y) to solve for b. So, the equation will be y = 2x + 3.

Step-by-step explanation:
any number that can be written as a fraction is rational, it is also a termintating decimal.
Answer:
Step-by-step explanation:
tan x = ( sin x ) / ( cos x )
tan²x + 1 = sec²x
sec x = ± √(tan²x + 1)
sec x = 1 / cos x
~~~~~~~~~~~~
tan x = 4 and sin x < 0
cos x - ?
<u><em>If tan x > 0 and sin x < 0 ⇒ cos x < 0</em></u>
sec²x = 16 + 1 = 17 ⇒ cos²x =
cos x = -
