Answer:
y=-3x-6
Step-by-step explanation:
what’s the answer to this ?
Answer:
First choice
Step-by-step explanation:
It passes through (4, 0) and (0, -4)
Slope = (0 - (-4))/(4 - 0) = 4/4 = 1
so y - 0 = 1*(x - 4)
x - y = 4

do the lengths 30.1, 0.8, 31 make a triangle & why
Step-by-step explanation:
If this were to make a triangle, then 30.1 and 0.8 would be the shorter sides and 31 would be the longest side.
The sum of the lengths of the shorter sides is 30.1+0
8=30.9.
Since this is less than the length of the segment that would be the longest side, by the triangle inequality theorem, these side lengths would not make a triangle.

The sum of two numbers is 64. The difference between the numbers is 14. Write a system
to find both numbers. Remember to show all work.
Answer:
They say that the sum of the two numbers (x and y) is 64, so we can write our first equation by adding them and setting that sum equal to 64:
x + y = 64
The question also tells us that their difference is 14. Similarly to before, we'll just subtract the two numbers and set that difference equal to 14:
x - y = 14
Now from here, you know how to continue with substitution to find the values for x and y. Just remember when you get a word problem to break it down and look for key words like sum, difference, or product, and from there you'll be able to build your system of equations.

NoCan some one help me. Asset capital and liability please
Answer:
I hope this helps you.
Step-by-step explanation:
Assets are the economic resources belonging to a business. Assets could be money in a cash register or bank account, or items such as property, fixtures and furniture, equipment, motor vehicles, and stock or goods for resale. An important asset in businesses which sell goods or services on credit is money owed to the enterprise by customers. This asset is known as debtors.
Capital is the value of the investment in the business by the owner(s). It is that part of the business that belongs to the owner; hence it is often described as the owner’s interest.
Liabilities are the debts owed by the firm. The main types of liabilities are creditors (money owed by the business to suppliers of goods and services), bank overdrafts and bank loans.

12. P (7,r) = 5040. Find r
A. 5
B. 6
C. 7
D. 8
Answer:
B
Step-by-step explanation:
P(7,r) = 5040
[tex]P(n,r)=\dfrac{n!}{(n - r)!}\\\\\\n = 7 \\\\\dfrac{7!}{(7 - r)!}=5040\\\\\\7! = (7-r)!*5040\\\\(7-r)!=\dfrac{5040}{7*6*5*4*3*2*1}\\\\\\(7-r)!=\dfrac{5040}{5040}\\\\\\(7-r)!=1\\\\[/tex]
(7 - r)! = 1!
7 -r = 1
7 = 1 + r
7 - 1 = r
r = 6
Answer:
12. B or C
13. C
14. A
15. A
Step-by-step explanation:
These problems involve various counting techniques. For combinations and permutations, there are formulas to aid in the counting. For other situations, you may need to list possibilities.
__
12.P(7, r) = 5040 . . . . . given
P(7, r) = 7!/(7 -r)! = 5040
5040/(7 -r)! = 5040 . . . . . evaluate 7!
(7 -r)! = 1 . . . . . . . . . . . multiply by (7-r)!/5040
We know that both 0! and 1! = 1, so this has two solutions:
7 -r = 0 ⇒ r = 7
7 -r = 1 ⇒ r = 6
Both choices B and C are correct.
The attached calculator output confirms this result.
__
13.The formula of choice C is correct:
C(n, r) = n!/((n-r)!r!)
__
14.The number of permutations of the 9 letters is reduced by the numbers of permutations of letters that are indistinguishable. That is, the 9 letters can be rearranged 9! ways, but the 4 Es are indistinguishable, so a factor of 4! must be removed from that result. Similarly, the two Ns and two Ss are indistinguishable, so additional factors of 2! must be removed. The number of arrangements is ...
9!/(4!2!2!) . . . . matches choice A
__
15.The 5 students can be arranged in 5 consecutive chairs in P(5, 5) = 5! = 120 ways. Those 5 consecutive chairs can start in chairs 1 through 6, so there are 6×120 = 720 ways the 5 students can sit together in 10 chairs.

Step-by-step explanation:
Judy spent 3 hours driving 165 miles She thinks
she can reach her final destination in 4 more hours
if she averages 65 miles per hour. What is the total
length of the trip in miles? [Hint: To find distance,
multiply rate (miles per hour) by time.]
Step-by-step explanation:
she drove already 165 miles.
she will reach her destination, if she drives 4 more hours by going 65 miles/hour.
that would mean she would travel
65×4 = 260 miles
in these 4 hours.
so, the total trip is then 165 + 260 = 425 miles.
but what I find strange is that your teacher specified how long it took her to drive the first 165 miles.
as you can see above, it would make no difference for the calculation of the total trip length in miles.
this is either an attempt to confuse us, or the message is that Judy has to achieve an average of 65 miles/hour for the whole trip, and the problem definition was just imperfectly phrased.
if that is the case, then things look a bit different, as her average speed was only 165/3 = 55 miles/hour for the first 3 hours and 165 miles.
so,
(165 + x)/(3 + 4) hours = 65/hour
(165 + x)/7 hours = 65/hour
165 + x = 65 × 7 hours / hour = 65×7 = 455 miles
x = 455 - 165 = 290 miles
she would have to go
290 miles / 4 hours = 72.5 miles/hour
for these next 4 hours (and 290 miles) to reach an overall average speed of 65 miles/hour.
and the total trip would be then
165 + 290 = 455 miles
I am not sure, which your teacher wants here.
65 miles/hour average speed just for the next 4 hours, or to speed up that much for the next 4 hours that the overall trip average is then 65 miles/hour.
again, the phrasing of the problem definition suggests the first case, but the fact that the travel time for the first part of the trip is given could suggest the second case (as this information is not needed for the first case).

In a group of 25 students at lunch, 10 prefer ketchup on their hamburger, 10 prefer mustard on
their hamburger, and 5 like both ketchup and mustard on their hamburger. The rest of the
students in the group prefer neither. What is the probability that a student selected from this
group will prefer ketchup or mustard on their hamburger?
Answer:
15/25 or 3/5 or 60%
Step-by-step explanation:
P(K or M) = P(K) + P(M) - P(K and M)
= [tex]\frac{10}{25}[/tex] + [tex]\frac{10}{25}[/tex] - [tex]\frac{5}{25}[/tex]

Answer:
what are you looking for? are you looking for mean,median,and mode,
Step-by-step explanation:
If so here they are.
Mean=13.1
The mean is the average of the numbers in the data set.
Median=13
The median is the middle number from it being sorted least to greatest.
mode=10,18
The mode is the number that appears most in a data set or sometimes numbers like right now it's numbers,both 10 and 18 appear twice.
Range=15
The range is the highest number subtracted by the lowest number. so what is 19 - 4?it is 15.
minimum=4
The minimum in a data set is the lowest number.
Maximum=19
The maximum is the highest number in a data set.
IQR is 8 because the IQR is based on the lower quartile subtracted by the higher quartile so 18 - 10=8
