Answer:
-3
Step-by-step explanation:
Select a point on the red line that crosses the graph at a corner like point (2,2). Start at the middle of the graph and go 2 spaces to the right on the x axis and then 2 spaces up. Now you will be a the point (2,2). Do you see how the right line is hitting at the top left corner of the square?
From this point, count how many spaces up and how many spaces to the left to get to the next spot that the red line touches a corner. If you go up 3 spaces and left 1, you have found the next corner. The slope is -3/1 or -3.
The slope is negative because the x and y's are going in different directions, as the x is getting bigger, the why is getting smaller, or another way of looking at it, is that I went up to the find slope and up is positive, but then I went left 1 and left is toward the negative numbers. A positive divided by a negative is a negative, so the slope is negative.
Answer:
75
Step-by-step explanation:
By "composite" we mean "numbers that can be factored further."
The numbers between 10 and 20 but not including 10 or 20 are:
12, 14, 15, 16, 18
12, 14, 15, 16 and 18 are all composite numbers (all can be factored).
Their sum is 75.
Answer:
5.48
Step-by-step explanation:
First, we convert all the fractions into improper fractions. 1 3/7 is 10/7, 3 5/9 is 32/9, and 1/2 stays the same. then we find a common denominator, which would be the LCM of 7, 9 and 2, which is 126. Finally, we rewrite the fractions with the common denominator of 56, and we get 180/126, 448/9 and 63/126. adding these together we get 691/126, which is approximately 5.48412698, which we can round to 5.48
A all squares have the sides
