It’s 100 but the other person explains it a lot better
Leni [432]2 years ago
5 0

Answer:

100

Step-by-step explanation:

let 's' = score on 6th test

[88(5) + s] ÷ 6 = 90

\frac{(440+s)}{6} = 90

cross-multiply to get:

440 + s = 540

s = 100

Use the following graph of the function f(x) = x3 − 3x2 − x + 3 to answer this question:
WITCHER [35]

Answer:

the average rate of change is equal to 0

Step-by-step explanation:

we have

f(x)=x^{3}-3x^{2}-x+3 -----> a cubic function

For x=-1

The value of f)x) is equal to

f(-1)=0 -----> see the graph

For x=3

The value of f(x) is equal to

f(3)=0 -----> see the graph

so

we know that

the average rate of change  using the graph is equal to

\frac{f(b)-f(a)}{b-a}

In this problem we have

f(a)=f(-1)=0

f(b)=f(3)=0

a=-1

b=3

Substitute

\frac{0-0}{3+1}=0

Given f(x)=3x-2 and g(x)=-1/3x +2/3, determine if g(x) and f(x) are inverse functions?
marin [14]
When dealing with inverse functions, I like to put them in terms of x and y to make it easier. y=3x-2 and y=-1/3x+2/3
to find the inverse of a function, one method is to switch the variables and then solve for the same variable as the first time, so the inverse of y=3x-2 is x=3y-2, which we now solve for y again.
x=3y-2 => x+2=3y => y=1/3x+2/3 which is not the same as y=-1/3x+2/3
Final answer:
No, f(x) and g(x) are not inverse functions.
Hope I could help :)
