Answer:
64
Step-by-step explanation:
*the sum of a triangle in degrees is 180*
44-72= 116
180-116= 64
A. C = 17h + 15
b. 83 = 17h + 15
-15 - 15 subtract 15 from both sides
68 = 17h
------------
17 divide both sides by 17
4=h
They cleaned the house for 4 hours
c. C = 20x
to do this last part, you would put both equations into the calculator under y=, then look at the table to determine when the price is the same. According to the calculator, the price is the same at 5 hours
Third angle = 180 - (44 + 72) = 180 - 116 = 64 degrees answer
Answer:
B
Step-by-step explanation:
A is false because y-intercept is (0,0)
C is false because x-intercept is (0,0)
D is false because domain is all real numbers
E is false because range is all real numbers
F (see B)
