Hi this is algebra math. It’s been a while since I’ve been on this app but I need some help on if the problem graphed the slope

right or wrong.

The graph is wrong, the slope is correct but because the sign is less than y that means the line on the graph should be dotted not solid.

A)clara believes the sequence 3,9,27,81,243 is arithmetic. Do you agree with clara?Explain your reasoning.

This is NOT an arithmetic sequence because there is no common difference. It is a geometric sequence because there is a common ratio. Meaning that each term is a constant ratio or multiple of the previous term. The recursive rule for this geometric sequence is:

a(n)=3*a(n-1), a(1)=3

Please help! Given the function problem

dedylja [7]

Answer:

B

Step-by-step explanation:

So we have the function:

$f(x)=\frac{9}{5}x+32$

To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:

$x=\frac{9}{5}f^{-1}(x)+32$

Subtract 32 from both sides:

$x-32=\frac{9}{5}f^{-1}(x)$

Multiply both sides by 5/9. The right side will cancel. Thus:

$f^{-1}(x)=\frac{5}{9}(x-32)$

Our answer is B.

And we're done!
