Answer:

d=4

Step-by-step explanation:

We are given the equation:

4d-4=5d-8

and asked to solve for d. In order to solve for d, we must isolate it on one side of the equation.

First, subtract 4d from both sides of the equation.

(4d-4d)-4=(5d-4d)-8

-4= (5d-4d)-8

-4= d-8

Next, add 8 to both sides of the equation.

(-4+8)=d-8+8

(-4+8)= d

4=d

Let's check our solution. Plug 4 in for d and solve.

4d-4=5d-8 (d=4)

4(4)-4=5(4)-8

Multiply 4 and 4.

16-4=5(4)-8

Subtract 4 from 16.

12= 5(4)-8

Multiply 5 and 4.

12= 20-8

Subtract 8 from 20.

12=12

The statement above is true, so we know our solution is correct.

The solution to the equation is d=4.

Answer: Population parameter

Step-by-step explanation: The parameter can be defined as a numerical value used to describe an entire population. The population describes all the entire values or members belonging to a particular group. Hence, numerical values which are used to explain the characteristic of the population is called the population parameter. Sample statistics on the other hand are numerical values associated statistical properties of a sample which is a subset of a certain population.

In the instance given above, 43% represents the population parameter which describes the percentage number of Democratic voters out of the entire population of voters in the city.

Answer:

[tex]\Large \boxed{2. \ x=\pm \sqrt{k}}[/tex]

Step-by-step explanation:

[tex]x^2 =k[/tex]

k is a real number.

We take the square root of both sides of the equation.

[tex]\sqrt{x^2 } =\pm \sqrt{k}[/tex]

Simplifying the equation.

[tex]x=\pm \sqrt{k}[/tex]

Answer:

x = ±√k

Step-by-step explanation:

If:

[tex]x^2 = k[/tex]

We'll take square root on both sides

=> [tex]\sqrt{x^2} = +/- \sqrt{k}[/tex]

=> x = ±√k

Answer:  The fraction [tex]\frac{7}{17}[/tex]

This can be written as 7/17 if you are using a computer keyboard.

====================================================

Explanation:

The two negatives next to each other basically cancel each other out to form a positive or a plus sign

We have

[tex]-\frac{9}{85} - \left(-\frac{44}{85}\right)[/tex]

turn into

[tex]-\frac{9}{85} +\frac{44}{85}[/tex]

From here, we add the fractions. To do this, we add the numerators and place the sum over the common denominator 85. This is only possible since both denominators are the same number.

[tex]-\frac{9}{85} +\frac{44}{85} = \frac{-9+44}{85} = \frac{35}{85}[/tex]

The last thing to do is to reduce this fraction as much as possible.

We see that 35 and 85 have 5 as a common factor. Divide each number by 5 to get...

Therefore, [tex]\frac{35}{85} = \frac{7}{17}[/tex]

So overall,

[tex]-\frac{9}{85} - \left(-\frac{44}{85}\right) = \frac{7}{17}[/tex]

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

That's

Slope of the through points

(15, -6) and (-3, 13) is

Since the lines are parallel their slope are also the same

So slope of parallel line = - 19/18

Equation of the line using point (4,2) and slope -19/18 is

We have the final answer as

Hope this helps you

Answer:y=-1.583x-8.332

Step-by-step explanation:

First find slope from two points (-6-13)/(15+3)=-1.583

Now line is parallel so the slope would be same for the other line passing through (4,2) now as the general equation of line is

y=mx+c

2=-1.583(4)+c

Solving for c equals to -8.332

So final equation is

y=1.583x-8.332

Answer:

No

Step-by-step explanation:

What we have to do is find how much everything costs.

After we do that, we can compare that total cost with the amount she has to determine if she can afford everything.

Let's set up an expression to see how much everything costs.

2 Movie tickets: 7.25+7.25

Drink and Popcorn: 5.75

Total: 7.25+7.25+5.75

14.5+5.75

20.25

20.25>20

Therefore, they would not have enough money to purchase 2 tickets and drinks+popcorn.

[tex]x^3=\boxed{x}\cdot x^2[/tex], and

[tex]\boxed{x}(x^2+2x+1)=x^3+2x^2+x[/tex]

Subtract this from [tex]x^3[/tex] to get a remainder of

[tex]x^3-(x^3+2x^2+x)=-2x^2-x[/tex]

[tex]-2x^2=\boxed{-2}\cdot x^2[/tex], and

[tex]\boxed{-2}(x^2+2x+1)=-2x^2-4x-2[/tex]

Subtract this from the previous remainder to get a new remainder of

[tex](-2x^2-x)-(-2x^2-4x-2)=3x+2[/tex]

[tex]3x[/tex] does not divide [tex]x^2[/tex], so we stop here.

What we've done is to write

[tex]\dfrac{x^3}{x^2+2x+1}=x-\dfrac{2x^2+x}{x^2+2x+1}[/tex]

then

[tex]\dfrac{x^3}{x^2+2x+1}=x-2+\dfrac{3x+2}{x^2+2x+1}[/tex]

and we stop here because the remainder term [tex](3x+2)[/tex] has a degree less than the degree of the denominator.

Alternatively, we can be a bit tricky and notice that

[tex]x^2+2x+1=(x+1)^2[/tex]

Now,

[tex](x+1)^3=x^3+3x^2+3x+1[/tex]

so that

[tex]\dfrac{x^3}{(x+1)^2}=\dfrac{(x+1)^3-(3x^2+3x+1)}{(x+1)^2}[/tex]

We can divide the first term by [tex](x+1)^2[/tex] easily to get

[tex]\dfrac{x^3}{(x+1)^2}=x+1-\dfrac{3x^2+3x+1}{(x+1)^2}[/tex]

Next,

[tex](x+1)^2=x^2+2x+1[/tex]

so that

[tex]\dfrac{x^3}{(x+1)^2}=x+1-\dfrac{3((x+1)^2-(2x+1))}{(x+1)^2}-\dfrac{3x+1}{(x+1)^2}[/tex]

[tex]\dfrac{x^3}{(x+1)^2}=x+1-3+\dfrac{6x+3}{(x+1)^2}-\dfrac{3x+1}{(x+1)^2}[/tex]

[tex]\dfrac{x^3}{(x+1)^2}=x-2+\dfrac{3x+2}{(x+1)^2}[/tex]

which is the same result as before.

Answer:

The distance between the two piers is 3 miles.

Step-by-step explanation:

If in Tasha's drawing 2cm represents 0.5 miles between the two piers, and the distance between the two piers in Tasha's drawing is 12cm.

The answer is found by the rule of three:

2 cm : 0.5 miles

12 cm : X

X = (12 * 0.5) / 2

X = 3 miles.

The distance between the two piers is actually 3 miles.

Answer:

Zeroes : 1, 4 and -5.

Potential roots: [tex]\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20[/tex].

Step-by-step explanation:

The given equation is

[tex]x^3-21x=-20[/tex]

It can be written as

[tex]x^3+0x^2-21x+20=0[/tex]

Splitting the middle terms, we get

[tex]x^3-x^2+x^2-x-20x+20=0[/tex]

[tex]x^2(x-1)+x(x-1)-20(x-1)=0[/tex]

[tex](x-1)(x^2+x-20)=0[/tex]

Splitting the middle terms, we get

[tex](x-1)(x^2+5x-4x-20)=0[/tex]

[tex](x-1)(x(x+5)-4(x+5))=0[/tex]

[tex](x-1)(x+5)(x-4)=0[/tex]

Using zero product property, we get

[tex]x-1=0\Rightarrow x=1[/tex]

[tex]x-4=0\Rightarrow x=4[/tex]

[tex]x+5=0\Rightarrow x=-5[/tex]

Therefore, the zeroes of the equation are 1, 4 and -5.

According to rational root theorem, the potential root of the polynomial are

[tex]x=\dfrac{\text{Factor of constant}}{\text{Factor of leading coefficient}}[/tex]

Constant = 20

Factors of constant ±1, ±2, ±4, ±5, ±10, ±20.

Leading coefficient= 1

Factors of leading coefficient ±1.

Therefore, the potential root of the polynomial are [tex]\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20[/tex].

Answer:

False

Step-by-step explanation:

Step 1: Write out equation

-12 + n = -15

Step 2: Add 12 on both sides

n = -3

So our answer is -3 and not 3.

Answer: [tex]False[/tex]

The answer to this problem is [tex]n=-3[/tex]

To get -3 here is the work shown

Simplify both sides of the equation

[tex]n-12=-15[/tex]

Add 12 to both sides

[tex]n-12+12=-15+12\\n=-3[/tex]
