If you have edunuity, the answer is... Two parallel lines will have the same slope. The slopes of parallel lines have to be equal. The y-intercepts of those two lines have to be different, otherwise they would be the same line. The x-intercepts of the parallel lines would also be different.
Answer:sum =378 according to your new questions.
to find average temperature
use formula
average =sum of temperature /no of measuring day
=378/9=42 is your answer
Answer:
either 20* and 140*, or 80* and 80*
Step-by-step explanation:
Answer:
47-25=22
Step-by-step explanation:
range is highest number subtract the lowest number lol easiest of all for the dot plot it is last number and first number with dots
The two numbers are 120 and 60
Let's call the two numbers x and y. The first sentence translates into
from which we can derive
So, their product can be written as
This expression is a quadratic polynomial with negative leading coefficient, so it represents a parabola concave down. So, the vertex of the parabola is its maximum, which we can find as usual: given the parabola 
, its extreme point is located at 
.
So, in your case, since 
and 
, the maximum is located at
Now that we know y, we can deduce the value of x:
So, the two numbers are 120 and 60
