There doesn't seem to be enough information to answer problem 1.
I would ask your teacher for clarification.
=============================================
Problem 2
Answer: 47 cards--------------------------
Explanation
x = number of cards, which is some positive whole number.
Your teacher has provided these facts:
If I deal among four people, three cards remain. If I deal among three people, two cards remain.If I deal among five people, two cards remain.which I'll call "fact 1", "fact 2", "fact 3" in that order.
For now I'll focus on fact 3.
Recall that multiples of 5 either end with 0 or 5. Example: 25 is a multiple of 5, and so is 60.
Fact 3 says that we get a remainder 2 when dividing by 5. Therefore, x must be something like 25+2 = 27 or 60+2 = 62. I added 2 to each previous example mentioned earlier.
In short, the value of x must end with 2 or 7.
-------------------
Now focus on fact 1.
The multiples of 4 are {4, 8, 12, ...} all of which are even since 2 is a factor of each.
Add remainder 3 to each item to get {7, 11, 15, ...} and it should be fairly obvious that all of these items are odd.
What does this mean? It means we know 100% that x ends with 7 in the units digit. If x has 2 in the units digit, then x would be even, but it's not in the set {7, 11, 15, ...}
So this is very useful info that x ends with 7.
x could be any of these: {7, 17, 27, 37, ...}
-------------------
We've looked at facts 1 and 3 so far. The only thing left is fact 2.
List the multiples of 3 to get
{3, 6, 9, 12, 15, 18, ...}
then add on the remainder 2 giving this new updated set
{5, 8, 11, 14, 17, 20, ...}
We see that 17 is in that set which fits the criteria of "the number ends with 7". So it's possible that 17 is the answer.
But 17/4 = 4 remainder 1 which doesn't fit fact 1 (since we want remainder 3 instead).
But we can add on multiples of 3*5 = 15 to extend to this new set of
{17, 32, 47, 62, 77, ...}
then erase stuff that ends with 2 to get
{17, 47, 77, ...}
Through guess and check, 47 will work out as shown in the next section below. Therefore, 47 is the final answer.
-------------------
Check:
47/4 = 11 remainder 347/3 = 15 remainder 247/5 = 9 remainder 2We get the proper remainders mentioned earlier, so the answer has been confirmed.
-------------------
Side note: The convention for problems like this is to use the Chinese Remainder Theorem. However, I decided not to use it because I wasn't sure if your teacher has covered modulo arithmetic yet or not. If s/he has covered it, then I recommend using that method instead of what I posted above. It's a much more efficient option.

For breakfast, you have had 1/2 a serving of cereal and 1/4 cup of raisins, which count as one serving of fruit.
For breakfast, you have had one serving of cereal and one serving of fruit. In general, one serving of cereal is considered to be one cup, while one serving of fruit is considered to be one half cup. Therefore, in your bowl of oatmeal, you would have had two servings of cereal, and in your quarter cup of raisins, you would have had one serving of fruit.

Is (2,12)(2,12)left parenthesis, 2, comma, 12, right parenthesis a solution of the system?
The solution to the given system of linear equations is x = -2 and y = -8. That is, (-2, -8).
Solving system of linear equationsFrom the question, we are to determine the solution to the given system of linear equations.
The given system of linear equations is
y = 5x + 2 ---------- (1)
4x - y = 0 ---------- (2)
Substitute equation (1) into equation (2)
4x - y = 0
4x - (5x + 2) = 0
4x - 5x -2 = 0
-x -2 = 0
-2 = x
x = -2
Substitute the value of x into equation (1)
y = 5x+ 2
y = 5(-2) + 2
y = -10 + 2
y = -8
Hence, the solution is x = -2 and y = -8

8 cows can graze a field in 28 days. how long would 14 cows take to graze the same field?
If 8 cows can graze a field in 28 days as a result, 14 cows take 12 days to graze the same field.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that, 8 cows can graze a field in 28 days.
Suppose x is the number of days required to graze the same field.
A proportionality relationship is one that has an inverse proportion. When two quantities are inversely related when one quantity rises, the other falls. The number of hours needed to construct a wall serves as an illustration of inverse proportion. By the inverse proportional relationship,
6:x :: 14:28
x=(28×6) / 14
x=2 × 6
x=12 days
Thus, if 8 cows can graze a field in 28 days as a result, 14 cows take 12 days to graze the same field.

What is the transformation of a function?A function ix transformed when the graph of the function is translated, resized or reflected.
The formula for the transformation of a function, f(x) is y = a·f(b·(x + c)) + d
Where;
a indicates the graph of the function is dilated vertically
b indicates a dilation horizontally
c indicates a translation horizontally
d indicates a vertical translation
The transformation applied to the parent function is the f(x) is an addition of a term, d = 3, which is a vertical translation
In a vertical translation of the form f(x) ± d
When d > 0, the graph of f(x) is moved up d units to get the graph of f(x) + d
When d < 0, the graph of f(x) is moved down d units to get f(x) - d
The graph of y = |x| + 3, obtained from the parent function, y = |x|, by a transformation of d = +3, therefore, the graph of y = |x| is moved up 3 units to get the graph of y = |x| + 3

The y-intercept is y = 10, and that is the initial height of the flower in inches.
And the rate of change between n = 1 and n = 5 is:
R = 0.21
What is the y-intercept?For any function y = f(x), the y-intercept is the value that y takes when we evaluate in x = 0.
In this case, we have the exponential function:
g(n) = 10*(1.02)^n
Evaluating in n = 0 we get:
g(0) = 10*(1.02)^0 = 10*1 = 10
The y-intercept is y = 10, and it means that the initial height of the flower is 10 inches.
Now we want to get the average rate of change on the interval [1, 5].
Remember that for a function f(x) the average rate of change on an interval [a, b] is:
R= [ f(b) - f(a)]/(b - a)
In this case we will have:
R = [ g(5) - g(1)]/(5 - 1) = [g(5) - g(1)]/4
Where:
g(5) = 10*(1.02)^5 =11.041
g(1) = 10*(1.02) = 10.200
Replacing that:
R = [11.041 - 10.200]/4 = 0.21
This means that the plant increases about 0.21 inches per day on these 4 days.

HELP
Answer: 700x+1700
This represents the total amount spent over the x weeks that have gone by.
===========================================
Explanation:
x = number of weeks
700x = amount spent over those x weeks ($700 per week)
700x+1700 = total amount spent when adding on the $1700 tv.
------
An example:
Let's say x = 10 weeks have elapsed. He spends $700 a week, so 700x = 700*10 = 7000 dollars have been spent so far if we ignore the tv. Then add on the $1700 tv cost to get 7000+1700 = 8700 dollars total spent.
Then note how 700x+1700 = 700*10+1700 = 8700 matches what we got earlier.

The slope-intercept form of the equation of a line that passes through point (-3, 8) is y= -1/2x + 6. What is the point slope form of the equation for this line?
The point- slope of equation is y- 8 = -1/2 ( x+ 3).
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
line that passes through point (-3, 8)
and, line is y= -1/2 x + 6
From above equation the slope of line is -1/2
Now, the point slope form of line
y- [tex]y_1[/tex] = m (x- [tex]x_1[/tex])
y- 8 = -1/2 ( x - (-3))
y- 8 = -1/2 ( x+ 3)
