Answer:

Graphic A. (Upper left graphic)

Step-by-step explanation:

The roots of the fourth-order polynomial are, that is the values of x which make polynomial equal to zero:

$x = 1$ and $x = -5$

By comparing the results with each graphic, it is evident that option A corresponds with the function. (Upper left graphic)

△XYZ was reflected over a vertical line, then dilated by a scale factor of , resulting in △X'Y'Z'. Which must be true of the two

Igoryamba

Answer:

correct option is △XYZ ~ △X'Y'Z'.

Step-by-step explanation:

since ΔXYZ is dilated by some scale factor so, the resulting triangle can not be congruent to the ΔXYZ. so option 2 is wrong.

as we have explained that the two triangles are not congruent then it's sides and angles also can't be congruent so, option 3 is also incorrect.

As we don't know by what factor the triangle XYZ is dilated so we can't say anything about correctness of option 4 and 5.

ΔXYZ was reflected over a vertical line and then dilated so the resulting ΔX'Y'Z' is similar to ΔXYZ.

i.e., △XYZ ~ △X'Y'Z'.

Which graph shows a negative rate of change for the interval 0 to 2 on the x-axis?

vova2212 [387]

Answer:

<h2>Third graph.</h2>

Step-by-step explanation:

A negative rate of change refers to an decrease at certain interval.

In this case, we have to look a decrease between 0 and 2 along the horizontal axis.

So, if we observe the third graph, we'll se that inside the given interval, the graph is decreasing, that indicates the negative rate of change that's being ask.

Therefore, the correct graph is the third one.

Which expression is equivalent to the one below ?

maks197457 [2]

Answer: $\frac {X^6 \times Y^4}{X \times Y^2}$

Step-by-step explanation:

<u>1.SEPARATE THE VARIABLES AS X & Y IN NUMERATOR</u>

NOW,we can changes in the numerator variable ADDING THE POWERS THEN THE VARIABLES $X^{2+4} \times Y^{3+1}{/tex] [tex] X^{6} \times Y^{4}{/tex]2. KEEP THE DENOMINATOR AS ITS : [tex]X \times Y^{2}$
