If f(x)=x-2, which of the following is the inverse of F(x)
sergiy2304 [10]
The answer would be 2. This is because inverse means opposite, and since f(x)=-2, then that means the inverse would be 2.

Gina opened a bank account with $40. She plans to add $20 per week to the account and not make any withdrawals. After how many w
ZanzabumX [31]

Answer:

After 33 weeks.

Step-by-step explanation:

Let w be number of weeks.

We have been given that Gina opened a bank account with $40. She plans to add $20 per week to the account and not make any withdrawals. So the balance after w weeks will be 20w+40.

To figure out number of weeks Gina will have exactly $700 in her account, we will equate the balance after w weeks to 700.

20w+40=700

Let us subtract 40 from both sides of equation.

20w+40-40=700-40

20w=660

Upon Dividing both sides of our equation by 20 we will get,

\frac{20w}{20}=\frac{660}{20}

w=\frac{660}{20}

w=33

Therefore, after 33 weeks Gina will have exactly $700 in her account, excluding interest.

52 is what percent of 260​
chubhunter [2.5K]

if we take 260 to be the 100%, what is 52 off of it as a percentage?

\bf \begin{array}{ccll} amount&\$\\ \cline{1-2} 260&100\\ 52&x \end{array}\implies \cfrac{260}{52}=\cfrac{100}{x}\implies 5=\cfrac{100}{x} \\\\\\ 5x=100\implies x = \cfrac{100}{5}\implies x=20

The location of the vertex tells you the horizontal and vertical shift. (The parent function f(x) = x² has its vertex at the origin, (0, 0). The vertical distance of the point 1 unit left or right of the vertex in relation to the vertex tells you the vertical scale factor (stretch).

g(x) = f(x +3) -3
  horizontal shift left 3
  vertical shift down 3

h(x) = -3f(x)
  reflection across the x-axis
  vertical stretch of 3

d(x) = f(x -3) -3
  horizontal shift right 3
  vertical shift down 3
