Goshia [24]

Let

x-------> the number of dinner

y-------> the number of lunch

we know that

8x+5y \leq 42 -------> equation A

x=y ------> equation B

Substitute equation B in equation A

8[y]+5y \leq 42

13y \leq 42

y \leq 42/13

y \leq 3.23

so

the greatest number of lunch is y=3

x=y

Hence

the greatest number of dinner is x=3

therefore

the greatest number of meals is

x+y=3+3=6

<u>the answer is</u>

6

Which is the best approximation of the solutions to the system of equations graphed below?
Neko [114]

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)
