5 1.2
-3 7
6 1.2
2 -3
yes its a function, as long as the domain (input) doesnt have the same number with two different ranges (outputs) its a function
Answer:
and 
Step-by-step explanation:
we have the coordinates
A(2,7),B(2,2),C(7,6)
we know that
The mid segment of triangle ABC that is parallel to line AB is located between the mid point AC and the mid point BC
The formula to calculate the midpoint between two points is equal to

step 1
Find the mid point AC
we have
A(2,7),C(7,6)
substitute in the formula


step 2
Find the mid point BC
we have
B(2,2),C(7,6)
substitute in the formula


therefore
The endpoints of the mid segment of triangle ABC that is parallel to line AB are
and 
X^2(x+2)-4(x+2)
(x^2-4) (x+2) = 0
do you have to keep going/?
or thats all they want?
Answer:
Scale factor is 2/5 or 0.4
Step-by-step explanation:
Divide radius of smaller circle (2) by radius of large circle (5)
MAB = 360 - 255 = 105
<ADB = 1/2(mAB) = 1/2(105) = 52.5
Answer
52.5°
