Simplify the expression 8+10 (x+3) + x . Do not include spaces in your answer and type in the form similar to 2x+2.

Answer:

y = 0.44 x - 0.1

Step-by-step explanation:

Using the points (2.5, 1) and (27.5, 12) (first and last points of the plot - please see attached image), we obtain the following slope:

slope = (y2 - y1) / (x2 - x1)

slope = (12 - 1 ) / (27.5 - 2.5) = 0.44

Now we use this slope to complete the equation of the line through those points:

y = 0.44 x + b

1 = 0.44 (2.5) + b

1 = 1.1 = b

b = 1 - 1.1

b = - 0.1

Therefore, the equation of the line becomes:

y = 0.44 x - 0.1

Answer:

y = 0.44x + 0

Step-by-step explanation:

I am going to use the first and lowest and highest points on the graph to make an equation representing the approximate slope of this graph.

(2.5,1) and (27.5,12)

To find slope I am going to calculate change in y over change in x.

12 - 1 over 27.5 - 2.5 = 11/25 = 0.44

So far we have y = 0.44x + 0

To find "b" (the y-intercept) we are going to plug zero in for x, because the defintion of y-intercept is "the value of y when x = 0"

We get that the y intercept equals 0.

y = 0.44x + 0 or just y = 0.44x

Answer:

No Solution

Step-by-step explanation:

Substitute y = 4x - 11 in 4x - y = 11

4x - y = 11

4x - 4x - 11 = 11

-11 = 11

There is no solution because -11 does not equal 11.

Answer:

(12x + 18)/(x+9)

Step-by-step explanation:

We have: (x + 11x + 18)/(x+9). First simplify this equation by adding like terms.

(12x + 18)/(x+9), which is your answer. This is the final answer because we can't simplify this expression anymore.

The two numbers are 6 and 20 respectively.

A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

Given is that one number is 10 less than 5 times the second number. Their sum is 26.

Let the numbers be [x] and [y] repsectively. Then, we can write that -

x + y = 26        ..... Eq[1]

x = 5y - 10        ..... Eq[2]

We can write -

x + y = 26

5y - 10 + y = 26

6y = 36

y = 6

Then, we can write [x] as -

x = 5 x 6 - 10 = 30 - 10 = 20

x = 20

Therefore, the two numbers are 6 and 20 respectively.

Step-by-step explanation:

$1500-$250 = $1250

You need to save an additional $1250.

The question did not include a pay rate.

Suppose you earn x dollars an hour.

$1250 × (1 hour)/($x) = (1250/x) hours

You need to work 1250/x hours.

Answer:

12.5x+10

Step-by-step explanation:

I'm assuming that you want to simplify this, because there is no equal sign.

If you want to simplify, first combine like terms.

First solve the first half of the equation: 20x-7.5x=12.5x

Now solve the second half of the equation: 12-2=10, so we have 12.5x+10.

That's your answer: 12.5x+10

Answer:

x = 0.8

Step-by-step explanation:

Your equation is 5(4x - 1.5x) + 12 - 2. Simply, you have to solve for x.

First, you have to do distributive property. 5 x 4 and -1.5 (1.5 is negative as I plus-minus.) This will now lead you to have the equation 20x + -7.5x + 12 - 2.

Next, you subtract 12 - 2. Then add 20x + -7.5x. Your equation should be 12.5x = 10.

Since you want x by itself, you will divide all by 12.5 in which 10 divided by 12.5 is 0.8. So your final answer is

x = 0.8

Answer:

The 85% confidence interval for the population proportion that claim to always buckle up is (0.7877, 0.8441).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

They randomly survey 391 drivers and find that 319 claim to always buckle up.

This means that [tex]n = 391, \pi = \frac{319}{391} = 0.8159[/tex]

85% confidence level

So [tex]\alpha = 0.15[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.15}{2} = 0.925[/tex], so [tex]Z = 1.44[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8159 - 1.44\sqrt{\frac{0.8159*0.1841}{391}} = 0.7877[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8159 + 1.44\sqrt{\frac{0.8159*0.1841}{391}} = 0.8441[/tex]

The 85% confidence interval for the population proportion that claim to always buckle up is (0.7877, 0.8441).
