The point where a line passes through the x or y axis
According to the direct inspection, we conclude that the best approximation of the two solutions to the system of <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)
<h3>What is the solution of a nonlinear system formed by two quadratic equations?</h3>
Herein we have two parabolae, that is, polynomials of the form a · x² + b · x + c, that pass through each other twice according to the image attached to this question. We need to estimate the location of the points by visual inspection on the <em>Cartesian</em> plane.
According to the direct inspection, we conclude that the best approximation of the two solutions, that is, the point where the two parabolae intercepts each other, to the system of two <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)

You just need to divide the given numbers to get the answer.
For example,
Question: Chad reads 30 pages in 3 hours. How many pages can he read in 1 hour.
Answer: 30/3=10
Therefore, Chad reads 10 pages in 1 hour.
HOPE THIS HELPS!!!!!!!!
X = 11 because if you take 11 x 2 then you get 22 then add 5 to it then you got 27 or if you do it the algebraic way subtract 5 from 27 to get 2x = 22 then divide both sides by 2 to get x = 11
