What are the roots of the polynomial equation x cubed minus 5 x + 5 = 2 x squared minus 5? Use a graphing calculator and a system of equations. Round noninteger roots to the nearest hundredth.
–3, –5
–2.24, –2, 2.24
–2.24, 2, 2.24
3, 5

Answers

Answer 1

Answer:

Step-by-step explanation:

–2.24, 2, 2.24

Answer 2

The solution to the equation of the polynomial function [tex]x^3 - 5x + 5 = 2x^2 - 5[/tex] is (c) –2.24, 2, 2.24

How to determine the roots of the polynomial?

The function is given as:

[tex]x^3 - 5x + 5 = 2x^2 - 5[/tex]

Split the function.

So, we have:

[tex]y = x^3 - 5x + 5[/tex]

[tex]y = 2x^2 - 5[/tex]

Using a graphing calculator, we have the x coordinate at the point o intersection of both equations to be

x = –2.24, 2, 2.24

Hence, the solution to the equation is (c) –2.24, 2, 2.24

What is the simplified expression of 5(3m+7) - 4?

Answers

Answer:

15m +31

Step-by-step explanation:

5(3m+7) - 4 = 15m + 35 - 4 = 15m +31

15m+31
use distributive property to get 5x3m= 15m and 5x7=35. Now the equation is 15m+35-4. Your final answer is 15m+31! :)

Which linear inequality will not have a shared solution
set with the graphed linear inequality?
O y < 5/3 x-2
O y < -5/3 x + 1
Oy > 5/3 x + 2
O y > -5/3 x + 2

Answers

Answer:

C. y > 5/3 x + 2

Step-by-step explanation:

A. y < 5/3 x-2

Will mostly share the region, same side of the parallel line

B. y < -5/3 x + 1

Will share almost half of the region

C. y > 5/3 x + 2

Left side of the parallel line, no shared region

D. y > -5/3 x + 2

Same as B.

[tex]y > \frac 53x +2[/tex] will not have a shared solution set with the graphed linear inequality

How to determine the linear inequality?

From the graph, we have the equation of the line to be:

[tex]y < \frac 53x +1[/tex]

The equation that have a shared solution must intersect with the line of the inequality.

From the list of options, we have:

[tex]y < \frac 53x -2[/tex] --- has the same slope, but a smaller y-intercept.

This means that the region of [tex]y < \frac 53x -2[/tex] is within the region of [tex]y < \frac 53x +1[/tex]

[tex]y < -\frac 53x + 1[/tex]

This has a different slope to the graph.

So, it will have a shared solution

[tex]y > \frac 53x +2[/tex] --- has the same slope, but a bigger y-intercept and a different inequality sign

This means that the region of [tex]y > \frac 53x +2[/tex] is outside the region of [tex]y < \frac 53x +1[/tex], and it will not have a shared solution

Hence, [tex]y > \frac 53x +2[/tex] will not have a shared solution set with the graphed linear inequality

Answers

[tex]\huge\boxed{\text{$74$ girls}}\ \huge\boxed{\text{$106$ boys}}[/tex]

Hey there! This situation can be modeled and solved using a system of equations. We'll use [tex]b[/tex] to represent the number of boys and [tex]g[/tex] to represent the number of girls.

[tex]\displaystyle{\left \{ {{b+g&=180} \atop {b&=g+32} \right.}[/tex]

Since we know what [tex]b[/tex] equals, we can substitute it into the first equation.

[tex]\begin{aligned}b+g&=180\\(g+32)+g&=180&&\smash{\Big|}&&\text{Substitute.}\\2g+32&=180&&\smash{\Big|}&&\text{Combine like terms.}\\2g&=148&&\smash{\Big|}&&\text{Subtract $32$ from both sides.}\\g&=74&&\smash{\Big|}&&\text{Divide both sides by $2$.}\end{aligned}[/tex]

Now that we know the number of girls, use the second equation to get the number of boys.

what's the LCD for 5 3 10 8 and 4?

And lastly what's the LCD for 2 . 10 . 5 , 8 , 4 ? someone pls help me.

Answers

Answer:

LCD for 5, 3, 10, 8, 4 is 120

LCD 2, 10, 5, 8, 4 = 40

Step-by-step explanation:

LCD (Least Common Denominator)

When adding fractions with different denominators, we must make all of them equal before attempting to add the numerators.

The minimum number that makes all denominators the same is the LCD. It uses the concept of the Lowest Common Multiple.

To find the LCD for 5, 3, 10, 8, 4, list all their prime factors:

5=5

3=3

10=2,5

8=2,2,2

4=2,2

Now multiply all the prime factors the maximum number of time it appears:

LCD=5*3*2*2*2=120

LCD for 5, 3, 10, 8, 4 is 120

Now for 2, 10, 5, 8, 4

2=2

10=2,5

5=5

8=2,2,2

4=2,2

LCD=2*2*2*5=40

LCD 2, 10, 5, 8, 4 = 40

Answer: A. it’s parallel

Step-by-step explanation:

The statement that must be true to prove m∠1 + m∠2 + m∠3 = 180

m∠1 + m∠2 = 180 - m∠3

Option B is the correct answer.

What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

m∠1 + m∠2 = 180 - m∠3

m∠1 + m∠2 + m∠3 = 180

Thus,

m∠1 + m∠2 = 180 - m∠3 is m∠1 + m∠2 + m∠3 = 180.
