x=3.5

6x-(4x-9)=25-9

6x-4x+9=25-9

2x+9=16

2x=7

x=3.5 so it is true when x=3.5

Answer: 4

Step-by-step explanation:

Inequalities help us to compare two unequal expressions. When 3a + 7b > 2a - 8b is solved for a, the result is a>-15b.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

When the inequality 3a + 7b > 2a - 8b is solved, the solution will be,

3a + 7b > 2a - 8b

3a - 2a > -7b - 8b

a> -15b

Hence, When 3a + 7b > 2a - 8b is solved for a, the result is a>-15b.

Answer: yea its 123445

Step-by-step explanation:

1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient​ is verified.

Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns.

As per the given data:

We are given the equation of a cubic polynomial x³ + 3x² - x - 3.

The zeroes of the given cubic polynomial are also given.

We have to verify that the zeroes of the cubic polynomial are correct, and they satisfy the relationship between zeroes and the coefficient​.

For a polynomial p(x) is p(a) = 0 then a is a zero of p(x).

Checking the given zeroes similarly:

For 1:

1³ + 3(1)² - 1 - 3 = 0

1 + 3 - 1 - 3 = 0

0 = 0

1 is a zero

For -1:

(-1)³ + 3(-1)² - (-1) - 3 = 0

-1 + 3 + 1 - 3 = 0

0 = 0

-1 is a zero

For -3:

(-3)³ + 3(-3)² - (-3) - 3 = 0

-27 + 27 + 3 - 3 = 0

0 = 0

-3 is a zero

For ax³ + bx² + cx + d = 0, the sum of all the roots should be equal to

= (-b)/a

Similarly, for x³ + 3x² - x - 3:

1 + (-1) + (-3) = (-3)/1

1 - 1 - 3 = -3

-3 = -3

1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient​ is verified.

Hence, 1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient​ is verified.

Answer:

  ABDEF -- 0.82 miles

Step-by-step explanation:

The lengths in feet of each of the segments have been worked out in the attachment to this problem:

  https://brainly.com/question/21623703

A shorter route could be one that leaves out stops C, G, H:

ABDEF has length (in feet) of ...

  AB +BD +DE +EF +FA = 817.7 +512.8 +804 +803.77 +1370.4 = 4308.67

There are 5280 feet per mile, so the route in miles is ...

  (4308.67 ft)/(5280 ft/mi) ≈ 0.82 mi

Shorter route ABDEF will have a length of 0.82 miles.

Answer:

Each shelter would get 121 blankets

And there would be 5 blankets left over

Step-by-step explanation:

One of the local homeless shelters received a donation of 852 blankets to help support the homeless population during the harsh winter months. They plan on distributing them to all 7 of the local shelters. How many blankets will each shelter get? Will there be any leftover? If so, how many?

From the above question

7 local shelters = 852 blankets

1 local shelters = x blankets

Cross Multiply.

7x = 852 blankets

x = 852 blankets/7

x = 121 5/7 blankets

Therefore, Each shelter would get 121 blankets

And there would be 5 blankets left over

Answer:

106 degrees

Step-by-step explanation:

180 -74 = 106

The second option is correct i.e. [tex]m[/tex]∠C = 106 degrees.

Two angles are said to be supplementary angles when they add up to 180 degrees.

Two angles are supplementary, if

a). one of its angle is an acute angle and another angle is an obtuse angle.

b). both of the angles are right angles.

This means that if A and B are the two angles then

[tex]m[/tex]∠A+[tex]m[/tex]∠B = 180 degrees

According to the given question we have

angles A and C are supplementary

and, [tex]m[/tex]∠A = 74 degrees

therefore,

the measure of angle C is calculated as

[tex]m[/tex]∠A + [tex]m[/tex]∠C = 180 degrees        (sum of the supplementary angles)

74 + [tex]m[/tex]∠C = 180 degrees            ( [tex]m[/tex]∠A = 74 )

[tex]m[/tex]∠C = (180 - 74)degrees            ( subtracting 74 degrees both the sides)

[tex]m[/tex]∠C = 106 degrees

Hence,  second option is correct i.e. [tex]m[/tex]∠C = 106 degrees.

Answer:

The simplest polynomial function is [tex]y = x^{4}-(7+\sqrt{13})\cdot x^{3}+(27+7\sqrt{13})\cdot x^{2}-(189+27\sqrt{13})\cdot x + 189\sqrt{13}[/tex].

Step-by-step explanation:

A n-th order polynomial in factorized form is defined by:

[tex]y = (x-r_{1})\cdot (x-r_{2})\cdot ...\cdot (x-r_{n-1})\cdot (x-r_{n})[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]r_{1}[/tex], [tex]r_{2}[/tex],..., [tex]r_{n-1}[/tex], [tex]r_{n}[/tex] - Roots of the polynomial.

We know that three roots, two real and a complex root. By Quadratic Formula,  a second order polynomial has two conjugated complex number of the form [tex]a + i\,b[/tex] and [tex]a - i\,b[/tex]. Hence, there is an additional zero: [tex]-i\,27[/tex].

By applying (1), we have the following polynomial when all roots are used:

[tex]y = (x-7)\cdot (x-\sqrt{13})\cdot (x-i\,27)\cdot (x+i\,27)[/tex]

By factorization and algebraic handling we have the simplest polynomial function:

[tex]y = [x^{2}-(7+\sqrt{13})\cdot x +7\sqrt{13}]\cdot (x^{2}+27)[/tex]

[tex]y = x^{2}\cdot (x^{2}+27)-(7+\sqrt{13})\cdot [(x^{2}+27)]\cdot x+7\sqrt{13}\cdot (x^{2}+27)[/tex]

[tex]y = x^{4}+27\cdot x^{2}-(7+\sqrt{13})\cdot x^{3}-(7+\sqrt{13})\cdot 27\cdot x +7\sqrt{13}\cdot x^{2}+189\sqrt{13}[/tex]

[tex]y = x^{4}-(7+\sqrt{13})\cdot x^{3}+(27+7\sqrt{13})\cdot x^{2}-(189+27\sqrt{13})\cdot x + 189\sqrt{13}[/tex]

The simplest polynomial function is [tex]y = x^{4}-(7+\sqrt{13})\cdot x^{3}+(27+7\sqrt{13})\cdot x^{2}-(189+27\sqrt{13})\cdot x + 189\sqrt{13}[/tex].
