Answer:
1.
Step-by-step explanation:
It's certain that it either rains or does not rain on any particular day.
Multiply the cost per hour by number of hours x and for option 1 you need to add the monthly fee:
A) option 1: C= 4x +35
Option2: C = 6.50x
B)
4x+35 < 6.50x
Subtract 4x from both sides:
35 < 2.50x
Divide both sides by 2.50 :
X < 14
You would need to rent more than 14 hours for option 1 to be cheaper.
X * y = 48
x - y = 13
x - y +y =13 +y
x = 13+y
x*y=48
13+y * y =48
13y+y²=48
y = -16 y=3
x- y = 13
x - (-16) =13
x + 16 =13
x +16-16 = 13-16
x = -3
Answer: The two numbers are -3 and -16.
-3 * -16 = 48
-3 - (-16) = 13
AC is a line with length of 7 units, from -7 to 0
BE is a line with length of 6 units, from 0 to 6
Two shapes are congruent if their length are the same, hence AC and BE is not congruent
