Select the correct answer. Consider the following system of equations. Use this graph of the system to approximate its solution.
vesna_86 [32]

The approximate solution to the given system of equations, considering the graph, is given as follows:

D. \left(-\frac{13}{4}, \frac{5}{2}\right).

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

On a graph, the solution of a system of equations is given by the intersection between the curves. In this graph, the intersection of the two curves happen close to x = -3.25, y = 2.5, hence the solution is approximated by:

D. \left(-\frac{13}{4}, \frac{5}{2}\right)

Describing Key Features of a Graph of a Polynomial Function:
Diano4ka-milaya [45]

<u>End behavior: </u>

The parent function is: f(x) = x³, which starts (from the left side) at -∞ and ends (on the right side) at +∞.

<u>Zeroes:</u>

f(x) = x³ + 2x² - 8x

0 = x³ + 2x² - 8x

0 = x(x² + 2x - 8)    

0 = x(x + 4)(x - 2)

0 = x         0 = x + 4         0 = x - 2

x = 0            x = -4              x = 2

<u>Intervals:</u>

Put the zeroes in order: -4, 0, 2

since f(x) is increasing from the left then the interval from -4 to 0 is positive and the interval from 0 to 2 is negative.

<u>Graph:</u>

Prove that the sum of two odd numbers is an even number
Maru [420]
Let a and b be odd number.
Because they are odd, by definition:
a = 2n + 1 
b = 2m + 1
If we add them up:
a + b = 2n + 1 + 2m + 1
         = 2n + 2m + 2
         = 2(n + m + 2)
         = 2k where k = n + m + 2

therefore a + b is always even.
