Answer:
(0,0) and (60,0)
Step-by-step explanation:
because they are the points on the x-axis
The expressions for the payment made to Mary are,
(Monday) 90 = 15m + b
(Tuesday) 62 = 8m + b
where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.
The equation that represents Mary's earning is
y = 4x + 30
For 20 students,
y = 4(20) + 30 = 110
For Lisa's earnings,
y = 8x + 15
Substituting 20,
y =8(20) + 15 = 175
Thus, Lisa would earn more than Mary by $65.
Answer:
Step-by-step explanation:
Since the figure is a square, the area is (1/3)^2 or 1/3 x 1/3
The area is 1/9 square inches.
From Pythagoras --> 10^2 + 12^2 = 244
from corner to corner it is root244 or about 15.6 feet
