Answer: $f^{-1}(x)=\frac{x}{7}+\frac{1}{14}$

Step-by-step explanation:

If we have y=7x-1/2, the inverse is where we solve for x instead of y.

We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.

Therefore, $f^{-1}(x)=\frac{x}{7}+\frac{1}{14}$ .

Hope that helped,

A geometric sequence has an initial value of 9 and a common ratio of 5. What function could represent this situation?

leonid [27]

Answer:

The functions that represent this situation are A and C.

Step-by-step explanation:

A geometric sequence goes from one term to the next by always multiplying or dividing by the same value.

In geometric sequences, the ratio between consecutive terms is always the same. We call that ratio the common ratio.

This is the explicit formula for the geometric sequence whose first term is k and common ratio is r

Which statement is an example of the symmetric property of congruence?

BabaBlast [244]

The correct answer is:

$\text{D) If }EFG \cong HJK, \text{ then } HJK \cong EFG.$

Explanation:

The symmetric property states that if two quantities are equal (or congruent), you can "flip" them around the equals sign (or congruence sign).

This means since EFG is congruent to HJK, then HJK is congruent to EFG.
