Answer:
Option A. 283 cm²
Step-by-step explanation:
to find the area of the shaded sector, we use the formula:
where area of the circle = πr²
∴ for the given circle,
= 
= 
= 282.6
≈ 283 cm²
The approximate area of the shaded sector is 283 cm².
First you should subtract 13 from -8.
Then divide the answer by -3.
Because you are dividing by a negative number, reverse the sign and you will get your answer.
13 - 3n < -8
-8 - 13 = ?
-3n < ?
?/-3 = n
Like in this example,
3 - 5n < 13
13 - 3 = 10
-5n < 10
10/-5 = -2
n > -2
Answer:
C
Step-by-step explanation:
This is a function because there is exactly one input for every output; X-Values can not repeat in a function.
I think that it would be 3x + 1.
2x + 3y +2(x-y) - 3x
2x + 3y + 2x - 2y - 3x ( get rid of the bracket by multipling 2 by the x -y)
2x + 2x - 3x + 3y - 2y ( group like terms)
x + y (final answer)
