The relationship between the cost of books and pens is an illustration of linear equation.
The linear equation is (a) 
From the question, we have:
x exceeds 2 times y by 10
Rewrite as:
x exceeds 2y by 10
Exceed means plus (+)
So, we have:
Equate the above equation to 0
Hence, the required equation is (a)

6x2(3x4)(x1 I’m pretty sure it’s right if not let me now and I’ll figure something out but..hope it helps u
Answer:
Step-by-step explanation:
<u>Given:</u>
- Cost price = $16.50
- Mark up rate = 120%
<u>Selling price is:</u>
- $16.50 + 120% =
- $16.50*2.2 =
- $36.30
You can basically just plug in the values. “1) (0,5) and (1,6)” is correct.
When you multiply a base with an exponent by a base with an exponent, you add the exponents together. (But you can only combine the exponents when the bases are the same)
For example:
(can't combine because they have different bases of x and y)
The expressions are equivalent because they both simplify and are equal to a^16
