I will give brainliest if you will help me. Please help me with my Algebra work. I would really appreciate it. Solve the following System of Equations Algebraically. Show how you started it. You do not need to show all of your work. Just make sure that I know how you got your answer. Make sure to write your answer as an order pair.
`-3x+5y=-6`
`8x+y=-13`

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

i got 10.28 but that rounds up to 10.3

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
