Answer:

7x^2+5x

Step-by-step explanation:

Given

Polynomial 1: 9x^2+8x

Polynomial 2: 2x^2+3x

We have to find subtraction of both

So,

9x^2+8x - (2x^2+3x)

First of all the brackets will be eliminated by multilying the minus sign

9x^2+8x-2x^2-3x

The terms with same power of variable will be written together

9x^2-2x^2+8x-3x

=7x^2+5x ..

A 2 -gallon container of window costs 31.36. what is the price per cup
irinina [24]

Answer:

0.98 $/cup

Step-by-step explanation:

The final answer asks for price/cup, as "per" means "divided by".

So, our final units will be in $/cup.

We are given that for every 2 gallons, it will cost $31.36.

In order to get from gallons to cups, we need to convert units.

In 1 gallon, there are 16 cups.

So, our conversion factor will be 16 cups/1 gallon.

\frac{31.36}{2} *\frac{1}{16} \\\\= 0.98$/cup

Important things to note:

- With these types of problems, it makes it much easier if you just figure out what units you need in the final answer, and then use conversions and dimensional analysis to get the answer

Please help me with this question :)​
klio [65]

Answer:

y>5/6

Step-by-step explanation:

5y+3>-7y+13

5y+7y>13-3

12y/12>10/12

y>5/6

This is an inequality, which shows where the variable y does or does not exist

from this we can say

y: (-infinity,5/6) (5/6, infinity]

or, y does not exist from (-infinity,5/6)

and does exist from (5/6, infinity]
