C)90 because if it go all the way around it would be 180 and I don't see that
Answer:
2/11
Step-by-step explanation:
6 = 2 x 3
6/11 x 1/3
= ( 6 x 1 )/( 11 x 3 )
= ( 2 x 3 x 1 )/( 11 x 3 )
Cancel 3 in both numerator and denominator.
= ( 2 x 1 )/( 11 )
= 2/11
Answer:
B. (x-9)^2 + (y + 7)^2 = 4
Step-by-step explanation:
The standard form of a circle is (x-h)^2 + (y-k)^2 = r^2. Hopefully you can memorize that, because it's very helpful in these problems!
(h,k) is our center, and r is our radius, so plug those values into the standard form:
(x - 9)^2 + (y + 7)2 = 2^2
2^2 = 4, so
<u>B. (x - 9)^2 + (y + 7)2 = 4 is our answer!</u>
It’s -9 because when multiplied it’s about -9
Answer:
y=3/2(x)+4
Step-by-step explanation:
Because line AB is perpendicular to line BC, the slope of AB is equal to 3/2. Substituting (-2,1) into the new equation gives us "1=3/2(-2)+b" which simplifies to 1=-3+b. This means that b=4.
