Catherine used the two points and the right triangle shown to find the slope of the line Catherine found the slope to be 1/10. I

blagie [28]

Answer:

Catherine is not correct (see the explanation)

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

the two points from the graph are

(4,40) and (7,70)

substitute the values in the formula

$m=\frac{70-40}{7-4}\\m=\frac{30}{3}\\m=10$

therefore

Catherine is not correct

9 of the students in Sarah's grade like to watch football and 12 like to watch figure skating. 7 students like to watch both foo

madreJ [45]

Answer:

Step-by-step explanation:

Total for football: 9 +7

Total for figure skating: 12 +7

NEW Total for football: 16

NEW Total for figure skating: 19

The question says that 9 people like football

The question says that 12 people like to watch figure skating

The question also says that 7 people like to watch both, and because of that, you should add 7 to both 9 and 12, but keep the new numbers separated from each other. So once we know the sum of 9 +7 is 16, and 12 + 7 is 19, we can subtract the two numbers, and get 3 as the answer. Because you are counting the number of times that you have to travel up or down to the other number, and so if you are on a set of stairs that go up to the 16 level and you are on the 14th level, you need to travel up 2 sets of stairs to get to level 16.

Hope that example helps and can help in the future with other problems!
