First, a little housekeeping!!
1+1+7x2+7y3+3+2x2−y3 needs to be written as <span>1+1+7x^2+7y^3+3+2x^2−y^3. The " ^ " signifies exponentiation and is essential here.
Now combine like terms:
7y^3-y^3 + 7x^2 + 2x^2 + 1 + 1 + 3
You'll get 6y^3 +9x^2 + 5.</span>
Answer:
y is the vertical axis. x is the horizontal axis. Replace any value in x to get your y value. The value you input as x is your x value. God this sounds confusing. I'd graph it for you but i don't know how to do that on Brainly.
Step-by-step explanation:
<span>A ratio is the number of one object of interest compared to the number of another object of interest that can be displayed using a fractrion.
