write an equation that describes the function
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

Matt and Bree are saving for a new car. At the end of 2013, their total savings was $12,500 . In 2014, total savings increased to $15,550 . How much did Matt and Bree save in 2014
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

Upon studying low bids for shipping contracts, a microcomputer manufacturing company finds that intrastate contracts have low bids that are uniformly distributed between 22 and 29, in units of thousands of dollars. (a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000. (Round your answer to four decimal places.)
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.

Math whizzes assemble! this is a tough one, this is a question on my study guide its a screenshot, any help would be appreciated.
Answer:
x = 6 y = -9 (I took a complicated route so if my explanation doesn't make sense It's fine)
Step-by-step explanation:
DAY = FUN
F = (7x+2y) = 24
If DAY = FUN then D = F making (7x + 2y) = 24
This means A = U so you have to find U with 24+126=150
A triangle is 180 degrees so you would do 180-150=30
U = 30
This also makes (8x+2y) = 30
8x + 2y = 30
-8x -8x
2y = 30 - 8x
Divide everything by 2
y = 15 - 4x
Doing this you can take 7x + 2y = 24 and plug in 7x + 2(15 - 4x) = 24
Multiply it 7x + 30 - 8x = 24
Add like terms -x + 30 = 24
Subtract 30 -x = -6
Divide by -1 x = 6
Now take one of the equations and plug it in 7(6) + 2y = 24
Multiply 42 + 2y = 24
Subtract 2y = -18
Divide by 2 y = -9

11B. Long Beach Towing Company charges $40 plus $5 per mile to
tow a car. The Five-Star Towing Company charges $70 plus $2 per
mile. After how many miles the charges for the two companied will
be the same?
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.

A numbers game run by many state governments allows a player to select a three-digit number from 000 to 999. There are 1000 such numbers. A bet of $5 is placed on a number. If the number is selected, the player wins $500. If any other number is selected, the player wins nothing. Find the expected value for the game.
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

I need help converting 3/5 into a decimal what should I write?
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.
Write the simplified answer.
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]
