For this question you are required to determine what is called a slope and y-intercept. To thoroughly explain, a slope is a constant factor while a y intercept is simply a number on the y-axis, for instance (0,1)
In order to determine slope, you would take two ordered pairs and use the following y2 - y1 divided by x2 - x1 to determine slope.
On the first attachment, take two ordered pairs.
-1 - (-3) divided by 1-0
2/1 = 2
m = 2
On the second attachment, use a principle called rise over run to determine the slope.
Using the method above, we “rise” two boxes and “run” one box, therefore the slope for the second attachment would be 2 and if we go down 2 we determine that the y-intercept is 0
Applying the explanation, we determine for the first attachment that the most sufficient answer is y = 2x - 3
The answer for the second attachment is y = 2x

the perez family has a rectangle fish tank. How much water will the tank hold if its length is 3 feet, its width is 2 feet, and its high is 3 feet
Answers
Hello there
Since there is 1 foot water in the tank the total volume = 3*2 * 1
= 6 cubic feet.
volume of 6 cu. feet corresponds to 1 foot of water in height, this will help you find your answer
The Perez family's rectangular fish tank can hold 18 cubic feet of water by multiplying the length, width, and height (3ft x 2ft x 3ft).
To calculate the amount of water the Perez family's rectangular fish tank can hold, we use the formula for the volume of a rectangle, which is length * width * height.
Given:
Length (l) = 3 feetWidth (w) = 2 feetHeight (h) = 3 feetThe volume (V) is calculated as:
V = l * w * h
V = 3 feet * 2 feet * 3 feet
V = 18 cubic feet
Therefore, the rectangular fish tank can hold 18 cubic feet of water.

Nuclear power provided 78% of the energy used in france in 2005. Write 0.78 as a fraction in simplest form.
Answers
Here we are given first that Nuclear power provided 78% of the energy used in france in 2005.
Now this was written in decimal as 0.78.
Then we have to write it in fraction form.
So first we have here two digits after the decimal, so in denominator we will have 100,
[tex]\frac{78}{100}[/tex]
Now we have to convert this into simplest form.
For that we have to find HCF of 78 and 100.
The HCF of 78 and 100 is 2, so we will divide both numerator and denominator by 2,
[tex]\frac{78/2}{100/2}[/tex]
This gives us:
[tex]\frac{39}{50}[/tex]
Answer: The simplest form of 0.78 as as fraction is 39/50.

:) hope this helps!
The domain of the function H(t), which models the height of a plant over time, would consist of integers ranging from -2 to 98 to represent each day of the plant's growth, including the two days before purchase.
Explanation:The question at hand is asking which type of number is more appropriate for the domain of a function, H(t), that models the height of Pooja's plant (in centimeters) t days after she bought it. The domain of a function includes all the possible inputs for the function, in this case, the number of days after Pooja bought the plant. Considering Pooja's plant sprouted 2 days before she bought it and lasted for 98 days, the best number type for the domain would be integers since the days are counted in whole numbers. However, if we include the 2 days before she bought it, the domain in context would be from -2 to 98. Therefore the domain would be {-2, -1, 0, 1, 2, ..., 98}, which are all integers.

For this case we have:
The area of the piece of fabric is given by [tex]A = a * b[/tex]
Where
[tex]a = \frac{1}{3}yards[/tex]
[tex]b = 3 \frac{5}{8}yards[/tex]
Substituting in the formula of the area we have:
[tex]A = \frac{1}{3}* 3 \frac{5}{8}\\[/tex]
[tex]A = \frac{1}{3}* (3 + \frac{5}{8})\\[/tex]
[tex]A = 1 + \frac{5}{24}[/tex]
[tex]A = 1\frac{5}{24}yards ^ 2\\[/tex]
Thus, the area of the piece of fabric is given by: [tex]A = 1\frac{5}{24}yards ^ 2\\[/tex]
Answer:
[tex]A = 1\frac{5}{24}yards ^ 2\\[/tex]
1/3 x 3 5/8 = (1/3 x 3) + (1/3 x 5/8)

Which of the following equations describes a line with an x-intercept of 3? A. x + y = −3 B. x − y = −3 C. x = 3
Answers
The correct equation which describes a line with an x-intercept of 3 is C. x = 3. This implies a vertical line where the x-value is always 3, regardless of the y-value.
Explanation:In response to your query about which of the following equations describes a line with an x-intercept of 3, the direct answer is C. x = 3. An x-intercept is the point where a line crosses the x-axis. For an equation to have an x-intercept of 3, it means that when y is 0, x equals 3. By plotting this on a graph, y can be any real number, but x will always stay 3. Therefore, the equation x = 3, which option C represents, is the correct description for a line with an x-intercept of 3.
It's important to note that, in terms of linear equations (generally represented as y = mx + b, where m represents the slope and b represents the y-intercept), x = 3 can be perceived as a vertical line that intersects the x-axis at point 3.

You have an allowance of $12.00. You buy a discount movies ticket that costs at least $3.50 and popcorn that costs $2.75. HOw much do much do you have for other spending?
Answers
Given
You have an allowance of $12.00
discount movies ticket that costs at least $3.50
popcorn that costs $2.75.
Find out the how much do much do you have for other spending.
To proof
Let us assume that the money for the other spending be x.
As given
total allowance = $12.00
discount movies ticket that costs at least = $3.50
popcorn costs = $2.75
than the inequality written in the form
3.50 + 2.75 + x ≤ 12.00
6.25 + x ≤ 12.00
x ≤ 5.75
you have money for other spending is atmost 5.75
when the movies ticket that costs at least $3.50
Hence proved
Final answer:
After purchasing a discounted movie ticket for at least $3.50 and popcorn for $2.75 from an allowance of $12.00, the student will be left with $5.75 for other spending.
Explanation:
The student is given a scenario involving budgeting and calculating remaining allowance after certain purchases. To find out how much money is left for other spending after purchasing a discounted movie ticket and popcorn, we subtract the total cost of these items from the initial allowance.
If the student has an allowance of $12.00 and buys a movie ticket for at least $3.50 and popcorn for $2.75, the calculation for the remaining allowance will be as follows:
Minimum amount spent on movie ticket: $3.50Amount spent on popcorn: $2.75We add these two amounts to find the total spent:
Total spent = $3.50 + $2.75 = $6.25
We then subtract the total spent from the initial allowance:
Remaining allowance = $12.00 - $6.25 = $5.75
Therefore, the student will have $5.75 left for other spending.

F(n) = 900 - 60(n-1) represent the amount oscar still need to repay on a loan at the beginning of month n .Find the amount oscar pays monthly and the month in which he will make his last payment.
Answers
Answer:Each installment will be of 60 and 16th will be the last payment.
Step-by-step explanation:
To find the monthly repayment by Oscar we first find the sequence.
For that first we put [tex] n=1 [/tex] in
[tex] F(n)=900-60(n-1)[/tex]
[tex] F(1)= 900-60(1-1) = 900 [/tex]
Now for [tex]n=2 [/tex]
[tex] F(2)=900-60(2-1)=840[/tex]
For [tex]n=3[/tex]
[tex] F(3)=900-60(3-1)=900-120=780[/tex]
So the sequenxe is 900,840,780......
As the amount is decreasing by 900-840=840-780=60
Therefore each installment will be equal to 60
For last payment amount will become 0
i.e.[tex]F(n) =0[/tex]
[tex] 900-60(n-1)=0[/tex]
[tex] 900-60n+60=0 [/tex]
[tex] 960=60n [/tex]
[tex]n = 960\div60[/tex]
[tex]n = 16 [/tex]
Last month will be 16th
The amount Oscar pays monthly is $900, and he will make his last payment in month 16.
Explanation:To find the amount Oscar pays monthly, we can subtract the amount he repays in each month from the previous month's balance. The formula F(n) = 900 - 60(n-1) represents the remaining amount Oscar needs to repay at the beginning of month n. By plugging in n = 1, we can find the initial balance and the amount he paid that month. To find the month in which he makes his last payment, we can set F(n) to zero and solve for n.

B. √36 and √49
C. √49 and √64
D. √25 and √64
Answers
Answer:
Option C.
Option B.
Step-by-step explanation:
By definition, the square of a number is that number times itself.
The square root of a perfect square is a whole number.
Since the square root of another number (not perfect square) is not a whole number, you can estimate it finding two perfect square roots that number is between.
1) Observe that 4 and 9 are perfect squares:
[tex]4=2^2\\9=3^2[/tex]
And 8 is between those numbers.
Therefore, the square roots [tex]\sqrt{4}[/tex] and [tex]\sqrt{9}[/tex] are used to estimage [tex]\sqrt{8}[/tex]
2) Notice 36 and 49 are perfect squares:
[tex]36=6^2\\49=7^2[/tex]
And 42 is between those numbers.
Therefore, the square roots [tex]\sqrt{36}[/tex] and [tex]\sqrt{49}[/tex] are used to estimage [tex]\sqrt{42}[/tex]
The square roots used to estimate √8 are √4 and √9 while the square roots to estimate √42 are √36 and √49.
Explanation:The two square roots that are used to estimate √8 are √4 and √9 since the value of √8 falls between the value of these two square roots (2 and 3). The reason why these are chosen is due to √8 being greater than √4 and less than √9. Similarly, the two square roots to estimate √42 are √36 and √49. The square root of 42 is more than the square root of 36 (which is 6) and less than the square root of 49 (which is 7). Therefore, to estimate the square roots, we find two perfect squares that the number falls between.
