Answer:
i think its 225 but i can still be wrong
Given:
The table of values is
Number of Students : 7 14 21 28
Number of Textbooks : 35 70 105 140
To find:
The rate of change and showing that the ratios of the two quantities are proportional and equivalent to the unit rate.
Solution:
The ratio of number of textbooks to number of students are




All the ratios of the two quantities are proportional and equivalent to the unit rate.
Let y be the number of textbooks and x be the number of students, then

Here, k=5.


Hence the rate of change is constant that is 5.
The ans is:
cos 20 =x/80
x=75.2
Answer:
d

Answer:
Step-by-step explanation:
You are given the point (x1, y1) = (-2, 7) and slope m = 5, and asked to fill in the blanks in the point-slope form ...
y -y1 = m(x -x1)
Put the numbers in there and you get ...
y -7 = 5(x -(-2))
Simplifying the right side gives you ...
y - 7 = 5(x + 2)
Then the blanks are filled with {-, 7, 5, +, 2}.
