Answer:
n - 13
Step-by-step explanation:
n-4-9
We can combine like terms.
n - (4+9)
n - 13
Refrection of point (0, 0) across y = 3 gives point (0, 6)
Refrection of point (0, -6) across the x-axis gives point (0, -6)
Answer:
Step-by-step explanation:
step 1
Find the measure of side c
Applying the law of cosines
substitute the given values
step 2
Find the measure of angle A
Applying the law of sine
substitute the given values
step 3
Find the measure of angle B
we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
so
substitute the given values
Since you need an isolated variable to use the substitution method, we need to re-arrange one of the equations. This will probably be easiest to do with the first one.
Add 5y to both sides of the first equation.
x=10+5y
Now, in the second equation, put in 10+5y in any spot that has an x.
2(10+5y)-10y=20
Distribute the 2 to both numbers in the parenthesis.
20+10y-10y=20
Combine like terms.
20=20
This means that the two equations are actually the same. You can see this if you multiply the whole first equation by 2
2(x-5y=10)
2x-10y=20, which is the same as the second equation. Therefore, the two equations are actually the same one.
Answer:
$283.05
Step-by-step explanation:
first divide $244.80 by 32, to find out how much you are making hourly. in this case you are making $7.65 an hour
next, multiply $7.65 by 5, to add the 5 hours, in this case you get $38.25.
next, add $38.25 to $244.80 and you get your answer!
