Determine the intercepts of the line
X-intercept: (__ , __)
Y-intercept: (__, __)
Answer:
x-intercept (0.3,0)
y-intercept (0,0.4)
Step-by-step explanation:
The line crosses the Y axis at a height of o.4 and an x value of 0
the x axis is crossed at a distance of 0.3 and a height of 0
solve for the value of the variable x
Answer:
[tex]\frac{-10}{3}[/tex]
Step-by-step explanation:
Cancel x+2 by multilying it with all terms.
x=2+4(x+2)
SImplify both sides
x=4x+10
Subtract 4 on both sides
−3x=10
Divide bot sides by -3
You get [tex]\frac{-10}{3}[/tex]

How do I write the equation to get the answer ?
Answer:
which type of equation just tell we are here to help if we can
Answer: Take the information given in the situation. Consider the relationships between the amounts, numbers and unknowns that are in the description.
If the word "is" or "are" is included in the description, that is equivalent to an equal sign.
Words like "and," "also" "more than" and "combined" are clues that there may be addition. "Total" often means the sum of an addition equation.
"From" and "difference" are clues that there is subtraction.
"Times" "by" and "of" art clues for multiplication. "Find the Area of. . ." dedinitely requires multiplication.
"Ratio," 'into' "per" and "among" are clues to division.
Use a letter x, y, d, t, or whatever helps identify the
Step-by-step explanation: Without a specific situation, it is impossible to give a specific answer.
Examples: The total number of seats in the auditorium is 125. 75 tickets have been sold already. How many more tickets are left. (This is the unknown)
The Total is the given 75 plus the unknown.
125 = 75 + x is the equation to start with
What is three-fourths of twelve? "What" is the unknown.

I have 3 times as many nickels as quarters. How many quarters do I have if I have
a total of $2.40
Answer:
18 Nickels, 6 Quarters
Step-by-step explanation:
For this problem, let's build a system of equations to find the number of nickels and dimes you have. Let N represent the number of nickels and Q represent the number of quarters you have.
The first equation, you have 3 times as many nickels as quarters:
N = 3Q
The second equation, you have a total of $2.40. Given we know nickels are $0.05 and quarters are $0.25:
0.05N + 0.25Q = 2.40
Now, let's use the two equations to find the number nickels and quarters you have.
N = 3Q
0.05N + 0.25Q = 2.40
0.05(3Q) + 0.25Q = 2.40
0.15Q + 0.25Q = 2.40
0.4Q = 2.40
Q = 6
Now, let's plug the value back into the equation:
N = 3Q
N = 3(6)
N = 18
And we can verify these values with the second equation:
0.05N + 0.25Q = 2.40
0.05(18) + 0.25(6) ?= 2.40
0.90 + 1.50 ?= 2.40
2.40 == 2.40
Therefore, we have found and verified the amount of Nickels and Quarters you have.
Cheers.

A fastfood coffee chain sells 780-gram bags of ground coffee for $16.99. Rhonda bought 3.9 kg. How much did she spend on coffee?
Answer:
$84.95
Step-by-step explanation:
Convert 3.9 kilograms to grams.
3900 grams.
Divide 3900 by 780.
The answer is 5.
Multiply 5 by $16.99
5 · 16.99 = $84.95
Rhonda spent $84.95 on coffee.

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of information. An equation relating packets of information is given by b = 1500p where p represents the number of packets and b represents the number of bytes of information.
a. How many packets would be needed to transmit 30,000 bytes of information?
Answer:
20
Step-by-step explanation:
If you have 1,500 per package and you need to find how many you will need to get 30,000 all you have to do is divide 30,000 by 1,500 and you get 20 packages. So the final equation would be 30,000=1500(20)
HOPE THIS HELPS!
Answer:20 Packets
Step-by-step explanation:Each packet is worth 1500b so 30,000b/1500b gives you 20 packets

Answer:
The slope of the line is 8.
Step-by-step explanation:
To solve this problem, we can use the formula for slope:
slope = m = (y2 - y1)/(x2 - x1)
If we substitute in two points from the table into this formula, we get:
slope = m = (11-3)/(1-0) = 8/1 = 8
Therefore, the slope of the line is 8.
We can also see this by looking at the table itself. Since both x and y are increasing together, we know that the slope should be positive. For every increase in 1 in x, y increases by 8; this confirms that the slope of the line is 8.
Hope this helps!

The length of a rectangle is 11 feet more than the width. If the perimeter is 46 feet, then what is the length of the rectangle, in feet?
Answer:
Hi there!
Your answer is:
The length is 17
Step-by-step explanation:
L= 11+w
P=46
perimeter formula:
W+W+L+L = P
W+W+(11+w)+(11+w) = P
First solve for W
4W+22 = 46
-22
4w=24
/4
w=6
Now plug in W for the L formula
l=11+w
L= 11+ 6
L=17

The Martians are trying to destroy Earth by launching an anti-matter rocket (it will be disastrous it will hit earth). In response, Earth launches 500 missiles towards the rocket. Each missile will hit the rocket with probability 0.01, independently of other missiles. What is the probability that Earth will be saved, if at least 3 missiles must hit the rocket in order to destroy it before it hits Earth
Answer:
The probability the earth is saved is [tex]P(X > 3) = 0.8753 [/tex]
Step-by-step explanation:
From the question we are told that
The number of missiles lunched by earth is n = 500
The probability that each missile will hit the rocket is p(x) = 0.01
Generally the expected number of missiles that will hit the rocket is
[tex] \lambda = n * p(x)[/tex]
[tex]\lambda = 500 * 0.01 [/tex]
[tex]\lambda = 5[/tex]
Gnerally the probability that Earth will be saved is mathematically represented as
[tex]P(X > 3) = 1 - P(X \le 2)[/tex]
=> [tex]P(X > 3) = 1 - P( X = 0 ) + P(X =1 ) + P( X = 2) [/tex]
Gnerally the probability distribution function of a Poisson distribution is
[tex]P(K) = \frac{e^{- \lambda t } * (\lambda * t)^k}{k!}[/tex]
Here t = 1
Hence
[tex]P( X = 0 ) = \frac{e^{-5} * 5^0 }{0!}[/tex]
[tex]P(X =1 ) =\frac{e^{-5} * 5^1 }{1!}[/tex]
[tex]P( X = 2) = \frac{e^{-5} * 5^2 }{2!}[/tex]
[tex]P(X > 3) = 1 - [ \frac{e^{-5} * 5^0 }{0!} + \frac{e^{-5} * 5^1 }{1!} + \frac{e^{-5} * 5^2 }{2!}][/tex]
[tex]P(X > 3)= 1 - [ \frac{0.00673 }{1} + \frac{0.033689}{1} + \frac{0.168449 }{2}][/tex]
[tex]P(X > 3) = 0.8753 [/tex]
