Answer:

\{(t,2t-5)\ where\ t\in(-\infty,\infty)\} is the solution set.

Step-by-step explanation:

y=2x-5......(1)\\3y=6x-15........(2)\\

Divide eqn(2) by 3.

y=2x-5

Hence both are the same lines.

if x=t where t be any point on real line iR.

from eqn (1)

y=2t-5

Hence solution set is =\{(t,2t-5):t \in R)\}

Which represents the polynomial written in standard form? 4m – 2m4 – 6m2 9 9 4m 2m4 – 6m2 2m4 – 6m2 – 4m 9 9 – 6m2 4m – 2m4 –2m4
miss Akunina [59]

The standerd form 4m – 2m^4 – 6m^2 +9.

We have given that the polynomial given below we have to find the standerd form  of the polynomial.

<h3>What is the standerd form of the polynomial</h3>

P(x)=a_nx^n+a_{n-1}x^{n-1}+......+a_1x+a_0

n=4

Standard form of the polynomial

4m - 2m^4 - 6m^2 + 9

Rearranginge term we get

=-2m^4 - 6m^2 + 4m + 9

The third term of the given polynomial is 0.

Therefore,the standard form is,

-2m^4 - 6m^2 + 4m + 9

There is a line whose Y intercept is -5 and whose slope is 0. What is its equation in slope – intercept form?
Aleonysh [2.5K]
<h2>Key Concepts</h2>
  • Linear equations
  • Slope-intercept form

Slope-intercept form looks like this: y=mx+b

  • <em>m</em> = slope
  • <em>b</em> = y-intercept

<h2>Solving the Question</h2>

We're given:

  • <em>m</em> = 0
  • <em>b</em> = -5

Plug the given values into y=mx+b:

y=0x-5\\y=-5

<h2>Answer</h2>

y=-5

the inequality below compares two rational numbers -6/18-17/27 if two numbers were plotted as values on a horizontal number line
Lyrx [107]

Correct question is;

The inequality below compares two rational numbers.

-6/18 > -17/27

If the two numbers were plotted as values on a horizontal number line, which statement would be true?

A) Both numbers lie to the right of 0, and −6/18 lies to the left of −17/27

B) Both numbers lie to the left of 0, and −6/18 lies to the left of −17/27

C) Both numbers lie to the right of 0, and −6/18 lies to the right of −17/27.

D) Both numbers lie to the left of 0, and −6/18 lies to the right of −17/27

Answer:

Option D

Step-by-step explanation:

In writing inequality on a number line, any number that is negative will lie to the left of zero while any number that is positive will lie to the right of zero.

Now in this case they are both negative, so they will lie to the left of zero.

Also, the number that is greater will lie to the right of the lesser number.. In this case -6/18 > -17/27. Thus, -6/18 will lie to the right of -17/27

Thus, option D is correct
