Answer:
a. m=3
b. m= -1/4
c. m= 0.25
d. m= 7
Step-by-step explanation:
y=mx+b
A.
2/3A=-24
time both sides by 3/2
A=-72/2
A=-36
B.
20=-B/0.2
times both sides by 0.2
4=-B
times -1
-4=B
distance between 2 points x and y is |x-y|
so
distance between A and B is distance between -4 and -72 or
|-72-(-4)|=|-72+4|=|-68|=68
the distance is 68
2/5 of the cake are left. Tiffany ate 1/5 and Omer ate 2x the amount, which is 2/5.
Answer:
c
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
2x + 18 + 3x + 12 = 180 (property of a cyclic quadrilateral).
5x = 180 - 18 -12
5x = 150
x = 30
So m < A = 2(30)+18
= 78 degrees.
