6 0

Answer:

A

The leading coefficient is negative.

Step-by-step explanation:

Quadratic equation:

A quadratic equation has the following format:

y = ax^2 + bx + c

The leading coefficient is a.

a negative:

The graph of the function is concave down, that is, it displays values that approach  negative infinity.

a positive:

The graph of the function is concave up, that is, it displays values that approach  up infinity.

In this question:

Displays values that approach  negative infinity, so the leading coefficient is negative, and the correct answer is given by option A.

Students in a cooking class made 4 1 2 quarts of soup. They served 4 5 of the soup to friends. Each serving is 3 5 quart. Hector
WINSTONCH [101]

The correct number of servings would be = 12/25

<h3>What is a cooking class?</h3>

A cooking class is defined as the class that is made up of students that are being thought how to prepare and serve different types of food.

The total amount of quarts of food made by the students = 4½.

The number of servings to friends = ⅘

The quantity of quarts in each serving = ⅗ quarts

Total number of quarts served = ⅘ × ⅗= 12/25

The correct number of servings = 12/25

Write an equation for the function using function notation
Softa [21]
(-1,3)(0,0)
slope(m) = (0 - 3) / (0 - (-1) = -3/1 = - 3

y = mx + b
slope(m) = -3
y int (b) = 0

ur equation is : y = -3x

function notation is : f(x) = -3x <==

What is the sum of the measures of the exterior angles of this triangle?
fgiga [73]

Answer:

360°

Step-by-step explanation:

We need only remember that the sum of the measures of the interior angles of a triangle is 180°.  Angle c and 112° form a pair of "straight angles," so they add up to 180°; as a consequence, Angle c = 180° - 112°, or 68°.

With two of the interior angles now known, we can calculate the third, Angle A:  It is 180° less (51° +  68°), or 180° - 119°, or 61°.

That means that the measure of Angle B is 180° - 61° = 119°

Looking at the pair C and 112°, we identify the exterior angle as 112°.

Looking at the pair A and B, or 61° and 119°, we identify the exterior angle as 119°.

Finally, looking at the pair 51° and (180° - 51°), or

51° and 129°, we identify the exterior angle as 129°.

Then the sum of the exterior angles 129° and 119° and 112° is 360°.
