The discriminant:
D = b² - 4 a c = 7² - 4· 3 · 2 = 49 - 24 = 25
D > 0 This function has 2 x-intercepts ( 2 zeroes ).
x 1 = (-7+5)/6 =-1/3
x 2 = (-7-5) / 6 = - 2

Use graphing to find the solutions to the system of equations.

Galina-37 [17]

In order to utilize the graph, first you have to distinguish which graph accurately pertains to the two functions.

This can be done by rewriting the equations in the form y = mx + b which can be graphed with ease; where m is the slope and b is the y intercept.

-x^2 + y = 1
y = x^2 + 1

So this will be a basic y = x^2 parabola where the center intercepts on the y axis at (0, 1)

-x + y = 2
y = x +2

So this will be a basic y = x linear where the y intercept is on the y axis at (0, 2)

The choice which depicts these two graphs correctly is the first choice. The method to find the solutions to the system of equations by using the graph is by determining the x coordinate of the points where the two graphed equations intersect.

25 ounces of guacamole are still expected to be available from batch.

Step-by-step explanation:

Given,

Quantity of guacamole in one serving = 2.2 ounces

Quantity of guacamole in one batch = 80 ounces

Quantity of guacamole in 25 servings = 2.2*25 = 55 ounces

Guacamole left = Quantity in batch - Quantity of 25 servings

Guacamole left = $80-55 = 25\ ounces\\$

25 ounces of guacamole are still expected to be available from batch.
