If it is just babysitting and yard work, then the obvious answer is yard work. Of it has other answers, then it would be a camp counselor. Also, never say it's not an exam, it would make people suspicious.

It’s yard work because he’s working the least amount of hours and making more money then babysitting so he can make the 1000$ faster

Indirect variation meaning

REY [17]

Answer:

See below.

Step-by-step explanation:

Indirect variation: - an example is

y = k/x where k is a constant , y and x are variables.

It is indirect because as x increases in value y will decrease.

If F(x) = +4, which of the following is the inverse of Fx)?

Viefleur [7K]

Answer:

$f^{-1} = \frac{ 7(x-4)}{2}$

Step-by-step explanation:

Given

$f(x) = \frac{2x}{7} + 4$

Required

The inverse function

$f(x) = \frac{2x}{7} + 4$

Replace f(x) with y

$y = \frac{2x}{7} + 4$

Swap x and y

$x = \frac{2y}{7} + 4$

Multiply through by 7

$7x = 2y + 28$

Solve for 2y

$2y = 7x - 28$

Solve for y

$y = \frac{ 7x-28}{2}$

Factorize

$y = \frac{ 7(x-4)}{2}$

Write as:

$f^{-1} = \frac{ 7(x-4)}{2}$

If the function f(x) = (2x - 3)2 is transformed to g(x) = (-2x - 3), which type of transformation occurred?

san4es73 [151]

Answer:

A. horizontal reflection

Step-by-step explanation:

Given:

$f(x)=(2x-3)^2$

$g(x)=(-2x-3)^2$

To identify the type of transformation.

Solution:

On close observation of the functions we find the that sign of $x$ has changed in $g(x)$ with other terms being constant.

<em>Thus, the transformation statement can be given as:</em>

$f(x)\rightarrow f(-x)$

As:

$f(x)=(2x-3)^2$

$f(-x)=(2(-x)-3)^2= (-2x-3)^2 = g(x)$

The transformation $f(x)\rightarrow f(-x)$ describes horizontal reflection of function across the y-axis.

Thus, $f(x)$ is horizontally reflected across y-axis to get $g(x)$ .
