Step-by-step explanation:
Answer: 5.53
Step-by-step explanation:
this is a straight forward addition
2.5+3.03 =5.53
to be clear or to specify, use the decimal point to make the sum:
2.5 = 2 + 0.5 and 3.03 = 3 + 0.03
2+3= 5 and 0.5 + 0.03 = 0.53
5 + 0.53 = 5.53 (but this is to long just to make it clear)
the two lines are perpendicular
y = -6 is a horizontal line ( slope of 0) and x = 1/6 is a vertical line (undefined slope). These are perpendicular to each other
D because of the vertical line test. The c input 2 has two different out puts meaning that it is not a function
