Answer:

$-11/6$

Step-by-step explanation:

Take two points an plug it in accordingly into the formula below

$y^2-y1/x^2-x^1$

Once it's all plugged in, you solve.

$15-4/4 - 10$

$-11/6$

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.

On a True/False test, Amy answered the first three questions wrong but answered the rest of the questions correctly. On the same

borishaifa [10]

Answer:

89.29%

Step-by-step explanation:

Given that Scott answered exactly two questions wrong. He answered the last question wrong, the 26 questions before it correctly, and the question before that wrong. Since Amy and Scott were both incorrect on the same question exactly once, Scott would have done wrong only in I or II or III question. If I question was wrong by both, total questions = 28, if II wrong total questions =29 and for iii total questions =30

Greatest possible percent would occur if total questions are less

i.e. when total =28

Greatest percent = $\frac{28-3}{28} =89.29%$

WRITE THE SUM OF THE NUMBERS AS THE PRODUCT OF THEIR GCF AND ANOTHER SUM 40+25

Dennis_Churaev [7]

The greatest common factor (GCF) of 40 and 44 is 4.

Explanation:

44 = 4 x 11

40 = 4 x 10

44 + 40 = (4 x 11) plus (4 x10) = 4 times (11+ 10)

-2/5 x -1 1/4 A) -1 1/10 B) -1/2 C) 1 1/10 D) 1/2

Harrizon [31]

The answer would be C b/c negative 2 times 11 is positive 22 and 2negatives equal a positive and then negative 5 times 4 equal 20 it would be 22/20 divide be top and bottom by 2 and you get your answer .
