What is the solution set to the inequality –3x + 5.9 ≥ –15.4 for x in the set {–10, –5, 0, 5, 10}?

Veronika [31]

–3x + 5.9 ≥ –15.4

subtract 5.9 from each side

-3x >= -21.3

divide by -3 which causes the inequality to flip

x <= 7.1

Answer: -10,-5,0,5

Which term could be put in the blank to create a fully simplified polynomial written in standard form?

Katena32 [7]

Correct Question:

Which term could be put in the blank to create a fully simplified polynomial written in standard form?

$8x^3y^2 -\ [\ \ ] + 3xy^2 - 4y3$

Options

$x^2y^2$ $x^3y^3$ $7xy^2$ $7x^0y^3$

Answer:

$x^2y^2$

Step-by-step explanation:

Given

$8x^3y^2 -\ [\ \ ] + 3xy^2 - 4y^3$

Required

Fill in the missing gap

We have that:

$8x^3y^2 -\ [\ \ ] + 3xy^2 - 4y^3$

From the polynomial, we can see that the power of x starts from 3 and stops at 0 while the power of y is constant.

Hence, the variable of the polynomial is x

This implies that the power of x decreases by 1 in each term.

The missing gap has to its left, a term with x to the power of 3 and to its right, a term with x to the power of 1.

This implies that the blank will be filled with a term that has its power of x to be 2

From the list of given options, only $x^2y^2$ can be used to complete the polynomial.

Hence, the complete polynomial is:

$8x^3y^2 -x^2y^2+ 3xy^2 - 4y3$

To answer that question

Mars2501 [29]

First, we get ax^2+bx+c. Next, we know that the line of symmetry is -b/2a. Since we know that there is a maximum value, the parabola is facing downwards, so a is negative. For random numbers, we can say that a = -0.5 and b=-10 (b needs to be negative for -b/2a to equal -10), getting -0.5x^2-10x+c. Plugging -10 in for x (since -10 is the middle it is the max), we get -50+100=50. Since the maximum needs to be 5, not 50, we subtract 45 from the answer to get it and therefore make c = -45, getting -0.5x^2-10x-45
