Consider the function.
Licemer1 [7]

Answer:

Option 4

Step-by-step explanation:

Given function is,

f(x)=2\frac{1}{2}-3\frac{1}{3}x

Steps to get the inverse of the given function,

Step 1,

Convert the function into equation,

y=2\frac{1}{2}-3\frac{1}{3}x

Step 2,

Interchange the variables 'x' and 'y',

x=2\frac{1}{2}-3\frac{1}{3}y

Step 3,

Solve the equation for the value of y,

x-2\frac{1}{2}=-3\frac{1}{3}y

x-\frac{5}{2}=-\frac{10}{3}y

-x+\frac{5}{2}=\frac{10}{3}y

-3x+\frac{15}{2}=10y

-\frac{3}{10}x+\frac{15}{20}=y

y=-\frac{3}{10}x+\frac{3}{4}

Step 4,

Convert the equation into inverse function,

f^{-1}x=-\frac{3}{10}x+\frac{3}{4}

For x-intercepts,

Substitute y = 0,

0=-\frac{3}{10}x+\frac{3}{4}

\frac{3}{10}x=\frac{3}{4}

x=\frac{10}{4}

x=\frac{5}{2}

x=2\frac{1}{2}

Therefore, x-intercept of the inverse function is (2\frac{1}{2},0).

Option 4 will be the answer.

I need help and I’ll give 100 points
svp [43]

Answer:

the student may have made the mistake because the student was paying more attention to how many blocks he was filling in rather than how much he was filling in.

to solve the problem correctly you would just switch the decimals

0.8 > 0.08

0.8 should have 80 blocks filled

0.08 should have 8 blocks filled
