Answer:

Step-by-step explanation:
The given expression is 
We multiply within the parenthesis to get:

Recall that: ![a^{\frac{m}{n} } =\sqrt[n]{x^m}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20%3D%5Csqrt%5Bn%5D%7Bx%5Em%7D)
We apply this property to get:


This simplifies to

We can simplify further

We rewrite as rational exponent 
Answer: c) y=1/5x
Step-by-step explanation: took da test
The x-intercept occurs when y = 0, so:
3x + 5(0) = 45
3x = 45
x = 15
Hey!
Simi bought study table = $ 9000
It means S.P = $9000
Profit = 20%
We know,
S.P = \frac{100+profit%}{100} \times C.P\\ S.P = \frac{100+20}{100} \times 9000\\ S.P = \frac{120}{100} \times 9000 \\ S.P = 10800
Now,
Profit = S.P - C.P
= 10800-9000
= $ 1800
