x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.
1. Stacey earns $15 each week plus $.50 for each customer on her paper route. She
wants to earn at least $25 each week. What equation can she use to find x, the
number of customers she needs to make exactly $25?
A x + 15 = 25
B 0.50x + 15 = 25
C 2x + 15 = 25
D 50x + 15 = 25
Answers
Explanation: the $0.50 is multiplied by the number of customers(“plus $.50 for each customer on her paper route”). So, it can’t be A, because the $0.50 is not in the equation. It can’t be c, because there should not be $2 for the number of customers(x). It can’t be D either because it’s 0.50, not 50. So, you’re left with B.
This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B
Answers
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.

The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?
160 ml
400 ml
1,600 ml
4,000 ml
Answers
Answer: 1,600 ml
Step-by-step explanation:
You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).
2,800 ml - 1,200 ml = 1,600 ml
I hope this helps :)
Answer: 1,600 mL
Step-by-step explanation:
1. convert the 1,200 mL to L, which is 1.2 L.
2. Subtract that value from 2.8 L, equaling 1.6 L
3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

The independent variable would be the one that could stand alone. So which one makes more sense? The amount of trips depends on how many buckets there are or the amount of buckets depends on the amount of trips?
Since the amount of trips DEPENDS on the amount of buckets... the amount of trips is the dependent and the buckets is the independent. so since there are 2 buckets carried up to hill for 1 trip, the first row on the table should look like this
2 1 (2,1)
So how many buckets would be on the hill after the second trip?
Well there are 2 more and 2 + 2 is 4. 2 trips = 4 buckets. So the next row would look like this
4. 2. (4,2)
Then u just keep going. Hint: Independent variable is counting by twos and dependent variable is counting by one's.
Then you graph the ordered pairs.

One afternoon, Dillon and 3 friends visit the zoo. They split the cost of parking the car evenly. Then each person buys a ticket to enter the zoo. By the end of the afternoon, each person has also purchased 2 bottles of water.
• Let p represent the parking cost.
• Let t represent the ticket cost.
• Let w represent the cost of a bottle of water.
Use the dropdowns to complete the statements.
(A) One way to express the total cost is to find the cost per person for a ticket and water. Then multiply this expression by

2.1 Factoring 2g2-9g-1
The first term is, 2g2 its coefficient is 2 .
The middle term is, -9g its coefficient is -9 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 2 • -1 = -2

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answers
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.

Cycle City charges an initial price of $15 plus $0.75 per house for bike rentals, which is represented by the expression 15 + 0.75h .
Complete the statement to describe the terms...
Answers
Answer: see below
Step-by-step explanation:
h represents the number of houses. How i know this:
(1) the question states that each house costs $0.75. So 0.75h means 0.75 times a number of houses.
(2) h is used because houses starts with h. Also, h can't represent bikes because the "bikes" only appears in 1 number and doesn't have anything per bike. It only appears once.
15 represents the initial price of bike rentals.
- It says in the question, "Cycle City charges an initial price of $15 plus $0.75 per house for bike rentals". All of the information related to what 15 stands for is underlined. "Initial price" means a 1 time price that doesn't repeat. the 0.75 repeats based on how many houses you get.
0.75h represents the total cost for any number of houses.
(1) The question says "$0.75 per house" which means that each house costs 0.75. The h next to the 0.75 only means a number of houses. Whenever you see "something per something", expect the first letter of the 2nd word to be placed after the number.
If it doesn't make sense, let's say that h=1. In other words, we are buying 1 house. 0.75h means 0.75xh, so 0.75x1= 0.75. It's true. 1 house costs 0.75. You can also do 0.75x2, 0.75x3, and so on.
I hope i could help :)))
Answer:
Step-by-step explanation:
h= number of houses
0.75= cost per house
15= the initial price (price first paid)

Kyra and 5 friends shared a bag of fruit snacks Each person got no more than 3 fruit snacks. the inequality x ÷ 6 ≤ 3 represents this situation. Solve the inequality to find the possible numbers of fruit snacks that were in the bag.
Answers
Answer:
There were 18 fruit snacks or less in the bag.
Step-by-step explanation:
The situation is given by the following inequality:
\(\frac{x}{6}\leq 3\)
So, if we isolate X, we have that:
\(x\leq 18\)
That implies that there were 18 fruit snacks or less in the bag.
