Answer:
(5,1)
Step-by-step explanation:
2x-y=9
(5,1)
There are many ordered pairs you could choose. For instance if x=0, then y=9. So you have the pair (0,9). If y=0, then 2x=9, so x=4.5. So you have the pair (4.5,0). You can keep making pairs by plugging in different values!

Question 4 please help me
Answer:
Step-by-step explanation:
I don't know what you were supposed to do with 3 but 4 looks much easier.
It's telling you to increase the side lengths by a factor of 3y
4x(3y) + 4x(3y) = 3y * 3y
12xy + 12xy = 9y^2
Perimeter = 24xy + 9y^2
I can't see anything else to do with this question. If you think I've misread it or there is more to it, leave me a note.

1. Combine the following expressions.
a√x + b √y - c√x
2. Combine the following expressions.
4m + 5√n - m + 6m - 3√n
3. Combine the following expressions.
√16a - √49a + √81a
4. Combine the following expressions
a√125y - b √45y
(NOTICE: If you do not know the answer, please do not answer. Trolls seeking points will be reported).
Answer:
1. (a-c)[tex]\sqrt{x}[/tex] + b[tex]\sqrt{y}[/tex]
2. 9m + 2[tex]\sqrt{n}[/tex]
3. 6a
4. (5a - 3b)[tex]\sqrt{5y}[/tex]
Step-by-step explanation:
1. since a and c share the same squareroot x, you can combine these together.
2. First add like terms together. 4m - m + 6m = 9m. Then 5[tex]\sqrt{n}[/tex] and -3[tex]\sqrt{n}[/tex] combined equals 2[tex]\sqrt{n}[/tex]
3. First simplify the square roots. squareroot of 16 is 4. square root of 49 is 7. square root of 81 is 9. They are all multiplied by a in the expression. Thus 4a - 7a + 9a = 6a
4. First simplify the radicals, they are not perfect. square root of 125 is equivalent to sqrt(25 * 5), which sqrt of 25 is 5, but we keep the sqrt of 5. For sqrt of 45, it is the same as sqrt9 * sqrt5. sqrt of 9 is the same as 3 and we keep sqrt 5. Thus we get the below:
5a[tex]\sqrt{5y}[/tex] - 3b[tex]\sqrt{5y}[/tex]
We can combine the two like terms and get the final answer above.

Two friends shop for fresh fruit Elena buy a watermelon for 8.55 and 3 pounds of cherries. Taniy buys a pineapple for 2.45 and 2 pounds cherries. Use the variable p to represent the price, in dollars, per pound of cherries. Write and simplify an expression to how much more Elena spent.
Answer:
$6.10 + p
Step-by-step explanation:
Given that:
p = price in $ per pound of cherries
ELENA:
Amount spent = 8.55 + 3p
TANIY:
Amount spent = 2.45 + 2p
How much more Elena spent :
Amount spent by Elena - Amount spent by Taniy
(8.55 + 3p) - (2.45 + 2p)
8.55 + 3p - 2.45 - 2p
8.55 - 2.45 + 3p - 2p
6.10 + p
$6.10 + p
Zachary buys a one pint bottle of juice for $3.20. What is the unit rate of the cost of the juice per fluid ounce?
How many fluid ounces of juice did Zachary buy?
Answer:
Zachary bought 16 ounces of juice
Step-by-step explanation:
First you figure out how many ounces are in a pint ( Which in case your wondering it's 16)
Then you take that number and divide $3.20 by 16 which gives you .20 cents.
You can double check my answer by multiplying .20 by 16 which gives you $3.20.

Answer:
-8, -3, 2 ad 7
Step-by-step explanation:
This graph shown is a polynomial function. The solution is the point where the curves cuts the x axis. From the diagram we can see that the curves cuts the x axis at four points.
The points are at x1 = -8, x2 = -3, x3 = 2 and x4 = 7
Hence the real solutions to the function f(x) = 0 are -8, -3, 2 ad 7

Two random samples of 25 people were asked how many 12-ounce cans of soda they consume each week. The first sample contained both males and females, aged 12-19. The second sample contained both males and females, aged 20-39. The results are shown in the table below. Using complete sentences, make one inference comparing the two groups, and explain your reasoning.
Answer:
One inference that can be made is that the age group of 12-19 consume more sodas than the age group of 20-39.
Step-by-step explanation: ok sooooo
The required individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19.
What is mathematical reasoning?Mathematical reasoning is the process of using logical thinking and mathematical concepts to solve problems, prove theorems, and develop mathematical models. It involves identifying patterns, making conjectures, and using deductive reasoning to arrive at logical conclusions based on given assumptions.
Based on the information given in the table, it can be inferred that individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19. This inference can be made because the mean and median values of the second sample (aged 20-39) are higher than those of the first sample (aged 12-19). Specifically, the mean for the second sample is 8.6 cans of soda per week, while the mean for the first sample is 6.96 cans of soda per week. Similarly, the median for the second sample is 8 cans of soda per week, while the median for the first sample is 5 cans of soda per week.
