Answer:

The answer is B.

Step-by-step explanation:

In a slope form equation, y = mx + b where m represents gradient and b is y-intecept. In the graph above, the line shows a negative gradient and the y-intercept is 5. So the possible option is B.

Answer: $5.64

Step-by-step explanation:

Let x represent 1 box of batteries

Let y represent 1 case of batteries

Given: 14x = 3y

Given: 158 = 14x + 3y

Use substitution: 158 = 14x + 14x

Simplify: 158 = 28x

Divide by 28: 5.64 = x

If f (7) = 22, then ff-1(22)) = [?]

lozanna [386]

Answer:

$f(f^{-1} (22))$ equals 22.

Step-by-step explanation:

For every input in a function, there will be one corresponding output. When taking the output of the function and inserting it as the input to the inverse function of the original, the output will be equivalent to the exact input of the original function. In this case, because $f(7)=22$ , that means $f^{-1} (22)$ will equal 7. Using this knowledge, you can find the value of $f(f^{-1} (22))$ , which will be $f(f^{-1} (22)) = f(7)=22$ , so $f(f^{-1} (22))$ equals 22.
