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)

Answer:
-74
Step-by-step explanation:
Answer:
m<G = 71
Step-by-step explanation:
Find x first
7x + 1 + 6x - 6 + 55 = 180
Combine like terms:
13x + 50 = 180
- 50 - 50
13x = 130
/13 /13
x = 10
Then apply to problem
7 (10) + 1
70 + 1
= 71
