Work shown above! Answer is y = -6(1/3)^x
edit: at the bottom it says "be must be 1/3" I meant "b must be"
9 15 *The denominator must be the same. 9 4 36
--- + ---- = --- × --- = ----
10 40 10 4 40
36 15 51 *Then simplify.
--- + --- = ----
40 40 40
51 11 * This the answer
--- = 1 ---
40 40
Answer:
D. 6.3
Step-by-step explanation:
Well you can make a triangle with the line PQ with it's height as 2 and base as 6.
Then you can use the Pythagorean Theorem to find the length of PQ.
a²+b²=c²
2²+6²=c²
4+36=c²
40=c²
c²=40
<em>Square root both sides</em>
c=
c≈6.3
Our answer is D. 6.3

Answer: $14.31
Step-by-step explanation:
Assuming it is the final price Natalie paid that you want:
Selling price = 0.9 * 15
= $13.50
