Let ​ f(x)=x2−3x−4​ . What is the average rate of change from x = 7 to x = 10? Enter your answer in the box.
just olya [345]
Rate of change is like slope. Change in y/ change in x
First we have to solve for the y.
x^2 -3x -4 when x = 7
7^2 -3(7)-4= 24 (7,24)
x^2-3x-4 when x=10
10^2-3(10)-4= 66 (10,66)

(66-24)/(10-7)

Ramon has 7/8 of a cup of cottage cheese. How many 1/4 cup servings can he make? Give an exact answer in decimal form.
krek1111 [17]

Answer: The answer in decimal form is 0.75

Step-by-step explanation: We know Ramon has 7/8 cup of cottage cheese.

He wants to know how many 1/4 cup servings can he make. 1/4 can also be written as 2/8 cup servings. 1/4 and 2/8 are equivalent.

He can only make three 1/4 cup servings of cottage cheese.

3 x 1/4 = 3/4

3/4 written in decimal form is 0.75
