Answer:
it ain't
Step-by-step explanation:
x = -8
y = 2

Answer:
x = 2
y = 6
Step-by-step explanation:
We have a system of equations and are asked to solve for x and y.
y = -2x + 10
y = 3x
Since both equations start with y, we can subtitute.
3x = -2x + 10
Solve for x :
Add 2x to both sides :
5x = 10
Divide 5 from both sides :
x = 2
Now substitute x in the second equation because it's more easier :
y = 3(2)
3(2)
6
y = 6

How many distinct permutations can be made from the letters of the word
“INDEPENDENCE”?
if anyone could answer, thank you (^-^)
Answer:
360
Step-by-step explanation:
Word INDEPENDENCE has I−1, N−3, D−2, E−4, P−1, C−1
There are six different letters in INDEPENDENCE
Now according to the question, we need to form 4 different letter words, So the selection of 4 words out of 6 is
[tex]^{6}C _{4}[/tex]
and making its arrangements
So total number of ways is
[tex]^{6}C _{4}[/tex] ×4!=360
The number of distinct permutations can be made from the letters of the word “INDEPENDENCE” is; 1663200
We are given the word INDEPENDENCE and it has;
I − oneN - threeD − twoE - fourP - oneC - oneThus, we see that there are six different letters and 12 letters in total in INDEPENDENCE
Now from the question, the distinct permutations that can be formed is;
12!/(3! × 2! × 4!) = 1663200

What is distance?
The length of the line segment connecting two places is called the distance between them. The length of the line segment connecting the specified coordinates can be used to compute the distance between two points in coordinate geometry. Let's look at the formula for calculating the distance between two points in two and three dimensions.
How to calculate?
If distance from my house to friend's house is x and from school to friend's house is y then distance=[tex]\sqrt{x^{2} +y^{2} }[/tex]
As it form 90degree so we can apply this formula.( Or can use trigonometric rule directly which is same.)
=[tex]\sqrt{9^{2}+12^{2}[/tex]
[tex]=15[/tex]
Therefore school and friend's house is 15 miles away from each other.

Which of these numbers is three less than a square number?
A new car is purchased for $17,000 and over time its value depreciates by one half every 3 years. What is the value of the car 19 years after it was purchased, to the nearest hundred dollars?
Answer:
The answer is "$238".
Step-by-step explanation:
Current worth[tex]= \$ 17,000[/tex]
depreciates by [tex]\frac{1}{2}[/tex] in 3 years.
time= 19 years
depreciates rate=?
Using formula:
[tex]\to \text{Worth= Current worth}(1- \frac{\text{depreciates rate}}{100})^{time}[/tex]
[tex]\to A_t=A_0(1-\frac{r}{100})^t[/tex]
calculates depreciate value in 3 year [tex]= \frac{1}{2} \times 17,000[/tex]
[tex]= 8,500[/tex]
so,
[tex]A_t=8,500\\\\A_0=17,000\\\\t=3\ years[/tex]
[tex]\to A_t=A_0(1-\frac{r}{100})^t\\\\\to 8,500= 17,000(1-\frac{r}{100})^3\\\\\to \frac{8,500}{17,000}= (1-\frac{r}{100})^3\\\\\to \frac{1}{2}= (1-\frac{r}{100})^3\\\\\to (\frac{1}{2})^{\frac{1}{3}}= (1-\frac{r}{100})\\\\\to 0.793700526 = (1-\frac{r}{100})\\\\\to \frac{r}{100} = (1-0.793700526)\\\\\to \frac{r}{100} = (1-0.8)\\\\\to r= 0.2 \times 100 \\\\\to r= 20 \%[/tex]
depreciates rate= 20%
[tex]\to \text{Worth= Current worth}(1- \frac{\text{depreciates rate}}{100})^{time}[/tex]
[tex]= \$ 17,000 (1- \frac{20}{100})^{19}\\\\= \$ 17,000 (1-0.2)^{19}\\\\= \$ 17,000 (0.8)^{19}\\\\= \$ 17,000 \times 0.014\\\\= \$ 238[/tex]

A fishing boat is hauling up a lobster trap. A machine called a winch pulls the trap up at a constant rate of 85 feet per minute.
Each ordered pair below represents a number of minutes elapsed, t, and a number of feet the lobster trap has traveled, d.
Which ordered pairs represent the correct relationship between distance and time? Select all that apply.
A.
(1,85)
B.
(0.85,1)
C.
(0.2,17)
D.
(3.5,297.5)
E.
(4,350)
Answer:
A, C, D
Step-by-step explanation:
We know that velocity is 85 feet/minute, and distance is velocity * time, so we can multiply 85 by time to see if it equals the output
(A) 1*85-85
(B) 0.85*85 = 72.75
(C) 0.2*85 = 14
(D) 3.5*85 = 297.5
(E) 4* 85 = 340

Write a rational function for the given scenario. There may be more than one correct answer.
Question 1. X-intercept: none
Vertical Asymptote: X = -3
Horizontal Asymptote: y = 0
Question 2. X-intercept: none
Vertical Asymptote X=2 & x= -2
Horizontal Asymptote: y = 0
Question 3 x-intercept: (3,0) & (-3,0) Vertical Asymptote: X=-1 & x= -4
Horizontal Asymptote: y = 1
Question 4. X-intercept: (-2, 0)
Vertical Asymptote: X = 4 & x=-5 Horizontal Asymptote: y=0
Need to make a rational function for each question.
Answer:
Q1: [tex]\frac{1}{x+3}[/tex]
Q2: [tex]\frac{1}{(x-2)(x+2)}[/tex]
Q3: [tex]\frac{(x-3)(x+3)}{(x+1)(x+4)}[/tex]
Q4: [tex]\frac{x(x+2)}{(x-4)^{2}(x+5) }[/tex]
Step-by-step explanation:
If there is a vertical asymptote at x=k, then the denominator must contain a term (x-k) or (x-k) raised to a positive integer power.
If there is an x intercept at k, then the numerator must contain a term (x-k) or (x-k) raised to a positive integer power.
If there is a horizontal asymptote of 0, then the highest power of x in the denominator must exceed the highest power of x in the numerator.
If thee is a horizontal asymptote of k, then the highest power of x in the numerator and denominator must be the same and the ratio of their coefficients (numerator to denominator) must be k.

Camille wants to set up a hot chocolate stand to raise money. She spends $40 on
hot chocolate and $0.25 for each paper cup. She uses the equation y=0.25x+40
to keep track of her spending. If Camille has $60 in donations to spend, what is
the maximum number of paper cups she can buy?
[tex]y = 0.25x + 40[/tex]
[tex]60 = 0.25x + 40[/tex]
[tex]60 - 40 = 0.25x + 40 - 40[/tex]
[tex]20 = 0.25x[/tex]
[tex] \frac{20}{0.25} = \frac{0.25x}{0.25} [/tex]

She can buy a maximum of 80 cups.
