A) Enter the corresponding values on the quadratic formula:

ollegr [7]

The answer is a = 0, b = -5, and c= 39.

Step-by-step explanation:

step 1 :

A quadratic equation means that it should have at least one squared term.

step 2 :

The standard form is ax² + bx + c = 0.

step 3 :

The solution to the quadratic equation is usually written in the form

x = (-b ± √(b2 − 4ac))/(2a)

where a = coefficient of x^2

b = coefficient of x

c = constant term

step 4 :

The given equation is -5x +32.

∴ The answer is a = coefficient of x^2 = 0

b = coefficient of x = -5

c = constant term = 39

1. What are the solutions (coordinate points) to the system of equations?

Leto [7]

Question 1

The given system of equations is:

$y = {x}^{2} + 5x + 6 \\ y = 3x + 6$

Equate the two equations:

${x}^{2} + 5x + 6 = 3x + 6$

Rewrite in standard form:

${x}^{2} + 5x - 3x + 6 - 6 = 0$

${x}^{2} + 2x = 0$

$x(x + 2) = 0$

$x = 0 \: or \: x = - 2$

When we put x=0, in y=3x +6, we get:

$y = 3(0) + 6 = 6$

One solution is (0,6)

When we put x=-2, into y=3x+6, we get:

$y = 3( - 2) + 6 = 0$

Another solution is (-2,0)

The solutions are; (0,6) and (-2,0)

Question 2:

The function is

$f(x) = {x}^{6} - {x}^{4}$

Let us put x=-x,

$f( - x) = {( - x)}^{6} - {( - x)}^{4}$

This gives:

$f( - x) = {x}^{6} - {x}^{4}$

We can observe that:

$f(x) = f( - x)$

This is the property of an even function.

Question 3:

The given function is

$f(x) = {x}^{2} + 3x - 2$

The average rate of change of f(x) from x=a to x=b is given as:

$\frac{f(b) - f(a)}{b - a}$

This is the slope of the secant line connecting the two points on f(x)

From x=2 to x=6, the average rate of change

$= \frac{f(6) - f(2)}{6 - 2} \\ = \frac{ {6}^{2} + 3 \times 6 - 2 - {2}^{2} - 3 \times 2 + 2 }{4} \\ = \frac{36 + 18 - 4 - 6}{4} \\ = \frac{44}{4} \\ = 11$

The average rate of change is 11

You can fly from Seattle to Boise for $137.50, from Boise to Witchita for $92.50 and from Witchita to Austin for $162.50. Use me

Vesnalui [34]

We add all these numbers up. 137.50 +162.50+92.50= 392.50$ Use a cacl or by hand

Which of the following is a trinomial with a constant term.

Sunny_sXe [5.5K]

<h2>The "option d: $y^5$ + 13x + 12" is a trinomial with a constant term.</h2>

Step-by-step explanation:

To check options:

a: x + 4y

Here, the coefficient of x = 1 and the coefficient of y = 4

b: $x^3$

Here, the coefficient of $x^3$ = 1

c: $x^4$ + 3 $y^2$ + 2y

Here, the coefficient of $x^4$ = 1, the coefficient of $y^2$ = 4 and the coefficient of y = 2

d: $y^5$ + 13x + 12

Here, the coefficient of $y^5$ = 1, the coefficient of x = 13 and

constant term = 12

Thus, the "option d) $y^5$ + 13x + 12" is a trinomial with a constant term.
