Answer:

Simplified form of: [tex](4x^2+x-6)(-6x-1)[/tex] is [tex]\mathbf{-24x^3-10x^2+35x+6}[/tex]

Step-by-step explanation:

We need to write the simplified answer of: [tex](4x^2+x-6)(-6x-1)[/tex]

We are multiplying both terms.

First -6x is multiplied with [tex](4x^2+x-6)[/tex] and then -1 is multiplied with [tex](4x^2+x-6)[/tex]

Looking at the table, we now just have to add the like terms to find the result.

[tex]-6x(4x^2+x-6)-1(4x^2+x-6)\\=-24x^3-6x^2+36x-4x^2-x+6\\Now\:combining\:like\:terms:\\=-24x^3-6x^2-4x^2+36x-x+6\\=-24x^3-10x^2+35x+6[/tex]

So, simplified form of: [tex](4x^2+x-6)(-6x-1)[/tex] is [tex]\mathbf{-24x^3-10x^2+35x+6}[/tex]

Answer:

y= –x + 1

Step-by-step explanation:

to write an equation in slope-intercept form, y = mx + b, calculate the slope, m, as rise/ run

The difference in y-values, rise, is –2

The difference between x-values is 2

–2/2 = m, the slope is –1

substitute for m, and it use any set of given y and x values in the equation to solve for b.

y= mx +b

–2 = –1(3) + b. Add 3 to both sides.

3 –2 = 3 –3 + b

1 = b

use the calculated m and b to write the equation with y and x

y = –x + 1

Answer:

The discounted price is $21

Explanation: Decimals represent fractions

with denominators of 10, 100, 1000, and so on.

Therefore, in order to write 3/5 as a decimal, we must first find a

fraction equivalent to 3/5 with a denominator of 10.

So we multiply the numerator and denominator

of 3/5 by 2 to get the equivalent fraction 6/10.

Since 6/10 is written as the decimal 0.6,

3/5 must be equivalent to 0.6.

Answer:

They saved $3000 in 2014

Step-by-step explanation:

Given

[tex]Savings (2013) = \$12500[/tex]

[tex]Total (2014) = \$15500[/tex]

Required

Determine the savings in 2014

This is calculated by subtracting the savings in 2013 from the total savings.

i.e.

[tex]Savings(2014) = Total(2014) - Savings(2013)[/tex]

This gives:

[tex]Savings(2014) = \$15500 - \$12500[/tex]

[tex]Savings(2014) = \$3000[/tex]

Hence, they saved $3000 in 2014

Answer:

The charges will be the same after 10 miles.

Step-by-step explanation:

Long Beach Towing Company:

Charges $40 plus $5 per mile. So after x miles, the charge will be of:

[tex]L(x) = 40 + 5x[/tex]

Five-Star Towing Company:

Chargers of $70 plus $2 per mile. So after x miles, the charge will be of:

[tex]F(x) = 70 + 2x[/tex]

After how many miles the charges for the two companied will be the same?

This is x for which:

[tex]L(x) = F(x)[/tex]

So

[tex]40 + 5x = 70 + 2x[/tex]

[tex]5x - 2x = 70 - 40[/tex]

[tex]3x = 30[/tex]

[tex]x = \frac{30}{3}[/tex]

[tex]x = 10[/tex]

The charges will be the same after 10 miles.

Answer:

The numbers described here are 39 and 11.

Step-by-step explanation:

Let's call the numbers a and b, a being the larger. We're told two things:

The larger of the two numbers is 17 more than twice the smaller.

Which we can express as:

a = 2b + 17

When the larger number is divided by the smaller, the quotient is 3 and the remainder is 6

And that can be expressed as:

a = 3b + 6

We can now take those two expressions and, noting that they both define a, we can say that they are equivalent, and solve for b:

2b + 17 = 3b + 6

3b - 2b = 17 - 6

b = 11

With b found, we can now take either of the first expressions, and solve for a:

a = 2b + 17

a = 2(11) + 17

a = 22 + 17

a = 39

Now we can check whether that is correct by plugging it into the other expression and seeing if b still comes to 11:

a = 3b + 6

39 = 3b + 6

3b = 33

b = 11

So we know that the answer is correct.

Answer:

The expected value for the game is of -$4.5

Step-by-step explanation:

The expected value of the game is given by each scenario multiplied by its probability.

Scenario 1: Player wins

1 correct number from a set of 1000, so probability of 1/1000.

In this case, the player spent $5, but earns $500, so a net of 500 - 5 = $495

Scenario 2: Player loses

Probability of 999/1000.

In this case, the player loses $5.

So, the expected value for the game is:

[tex]E = \frac{495*1}{1000} - \frac{5*999}{1000} = -4.5[/tex]

The expected value for the game is of -$4.5

Answer:

0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value lower than x is given by:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

Uniformly distributed between 22 and 29, in units of thousands of dollars.

This means that [tex]a = 22, b = 29[/tex].

(a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000.

This is P(X < 25). So

[tex]P(X < 25) = \frac{25 - 22}{29 - 22} = 0.4286[/tex]

0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.

Answer:

Adult-. $4

Student-. $2.50

Step-by-step explanation:

equation

1a + 3s = $11.50

3a + 2s = $17.00

$4+$2.50(3)=$11.50

$12+$2.50(2)=$17.00

or

1($4)+3($2.50)=$11.50

3($4)+2($2.50)=$17.00

sorry if this is a little confusing, this is a simpler equation-

$4.00+($2.50x3)=$11.50

($4.00x3)+($2.50x2)=$17.00
