By the rational root theorem, any rational zeros of

f

(

)

are expressible in the form

p

q

for integers

p

,

q

with

p

a divisor of the constant term

and

q

a divisor of the coefficient

of the leading term.

That means that the only possible rational zeros are:

±

1

±

We find:

f

(

So

x

Notice that the ratio between the first and second terms of the remaining cubic is the same as that between the third and fourth terms. So this cubic will factor by grouping:

Finally we can factor the quadratic as a difference of squares:

Answer:

The answer to your question is None

Step-by-step explanation:

A rational number can never be changed into irrational.

In mathematics, the irrational numbers are all the real numbers that are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.

Answer:

See below:

Step-by-step explanation:

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.

We can solve this problem in two steps, Comprehending, and Solving/Checking our answers. I'll be starting off with Comprehending.

Comprehending

We can solve the problem with substitution by finding out what one variable is equal to in terms of the second variable.

This is what we would call System of Equations where we need to find the point where the lines hit.

We can do this either with Graphing, or Algebra. In this case, we need to use substitution, so it has to be Algebraically.

Now that we know how to solve it/what to do, we can start solving.

Solving

We can solve the problem by first replacing y with its correct value in terms of x. Since we know the two equations, we can begin solving.

[tex]y=2x-11\\5x+3y=22[/tex]

We can solve it by inserting our y value into the y value of the second equation.

[tex]5x+3(2x-11)=22\\5x+6x-33=22\\11x=22+33\\11x=55\\x=5[/tex]

Now that we know our x value, we can solve for y by inserting it into an equation.

[tex]y=2(5)-11\\y=10-11\\y=-1[/tex]

Now that we have solved, we have gotten out point of (5,-1)

We can test this by inputting it into an equation. (Any of the latter).

[tex]5(5)+3(-1)=22?\\25-3=22?\\22=22[/tex]

Now that we have checked our answer and it appears correct, we have gotten our answer of (5,-1).

Answer:

(5, - 1 )

Step-by-step explanation:

5x + 3y = 22 → (1)

y = 2x - 11 → (2)

Substitute y = 2x - 11 into (1)

5x + 3(2x - 11) = 22 ← distribute parenthesis and simplify left side

5x + 6x - 33 = 22

11x - 33 = 22 ( add 33 to both sides )

11x = 55 ( divide both sides by 11 )

x = 5

Substitute x = 5 into (2)

y = 2(5) - 11 = 10 - 11 = - 1

solution is (5, - 1 )

Answer:

Slope=5

Step-by-step explanation:

Using slope formula, we have -9-(-14)/-1-(-2) which is 5/1, so our slope is 5

Answer:

slope is 5

Step-by-step explanation:

get 2 points and apply:

(-14-(-9))/(-2-(-1))=-5/-1=5

Answer:

New eq: 11x + 1. The line will become steeper.

Step-by-step explanation:

Slope is rise over run. In the original equation, y increased 4 times everytime x increased by one. In the new equation, y increased 11 times everytime x increased by one making it steeper.

Step-by-step explanation:

2[tex]x^{2}[/tex]= 4[tex]x[/tex] because 2 *2 = 4 + x = 4[tex]x[/tex]

since 7[tex]x[/tex] is a like term we add it to 4[tex]x[/tex] and it becomes : 11[tex]x[/tex]

Since 6 does not have a variable we do not add anything to it so, it stays the same and the simplified expression becomes : 11[tex]x[/tex] + 6

Answer:

950 g = 0.95 kg

35 mL = 0.35 dL

hope this helps

Answer:

35 mL = 0.35 dL

950 g = 0.95 kg

Step-by-step explanation:

This is the answer because:

1) For mL to dL, divide the volume value by 100: 35/100 = 0.35

2) For g to kg, divide the mass value by 1000: 950/1000 = 0.95

Answer:9810

Step-by-step explanation:

S.I = 810

Amount after 2 years = 9000+810

= 9810

Answer:

125

Step-by-step explanation:

You can find the interior angle next to the angle with the value of 100, because a straight line has an angle of 180, so that angle would be 80. You can do the same with the interior angle next to 135, with that angle having a value of 45.

The interior angles of a triangle always have the sum of 180, so to get the last interior angle add 80+45 and then subtract that from 180. That angle would be 55.

To get Y take the value of the interior angle subtract 55 from 180, which would be 125.

Answer:

x=3 and y=2

Step-by-step explanation:

These equations line up quite nicely, so let's use the elimination method.

x+y=5

+ x-y=1

-------------

2x=6.

Now that we added the two equations together, we only have x as a variable to solve. We now divide 2 from both sides

x=3.

Now we take our 3 and substitute it into one of the equations. I want to put it in the first one.

3+y=5.

We subtract 3 from both sides to get y=2.

We end up with the answers x=3 and y=2. If you plug them in to check, they make sense. 3+2=5 and 3-2=1. This answer is proven to be correct.

Step-by-step explanation:

1/8 x 5/6 as a fraction in simplest form

1/8 * 5/6 =

5/48

The fraction in simplest form is 5/48.

Given that are two fractions 1/8 and 5/6, we need to find the product of the fractions,

To multiply fractions, we multiply the numerators together and the denominators together.

In this case, we have 1/8 multiplied by 5/6.

1/8 x 5/6 = (1 x 5) / (8 x 6)

Multiplying the numerators (1 x 5) gives us 5, and multiplying the denominators (8 x 6) gives us 48.

Therefore, 1/8 x 5/6 simplifies to 5/48.

Step-by-step explanation:

Answer:

  41.0 cm

Step-by-step explanation:

The side length is 1/4 the length of the perimeter.

  s = P/4

The diagonal length is √2 times the side length.
