What is the area of the region bounded by the graph of the equation x^2+y^2 + 3 = -4y + 6x-1?
Answer:
9π
Step-by-step explanation:
What we need to do here is convert this equation into a standard circle equation;
x^2+y^2 + 3 = -4y + 6x-1,
x^2+y^2+4y-6x+1 = 0,
x^2-6x+(-3)^2 + y^2+4y+(2)^2 = 3^2
(x-3)^2 + (y+2)^2 = 3^2,
so we have a circle with a radius of 3, and hence the area of our region is π(3)^2 = 9π. correct!

(b) Multiply the integer and mixed number by multiplying fractions. What is the product?
Answer:
a)
\( - 11 \times 7 \frac{6}{7} \)
\( - 11 (7 + \frac{6}{7}) \)
\( - 11(7) + ( - 11)( \frac{6}{7} )\)

Terry is buying juice. He needs 3 liters. A half-liter of juice costs $2.39. A 250-milliliter container of juice costs $1.69. What should Terry buy so he gets 3 liters at the lowest price? Explain.
1. What are the two units of measurement used in this problem?
2. What do you need to do to the prices before you can compare the costs?
3. How can you convert the half-liter price to cost per liter? Explain.
4. How many 250 milliliter bottles are in 1 liter? Explain.
Answer:
Terry should buy the half liters.
1. Milliliters and Liters
2. For the milliliters you must multiply them by 12 because each milliliter container needs to be multiplied by 12 to have 3 liters, and for half liters, you must multiply the cost by 6 because there are 6 half liters in 3 liters.
3. You can convert the half liters to cost the same as the liters by multiplying them by 2 since 2 halves is 1 entire liter.
4. 1000 milliliters in 1 liter.
Step-by-step explanation:
Terry should buy the half liters because 6 half liters (equivalent to 3 liters) is $14.34, compared to 12 250 milliliter containers (equivalent to 3 liters) is $20.28.

QUESTION 7:
We are trying to find angles 1 and 2.
Known angle: 107˚.
In this question, we have 2 parallel lines with a transversal. A transversal is a line that passes through 2 parallel lines making it so that the angles on both sides are exactly the same.
Step 1: Find the measures of all the angles using the one we already know.
I will start with the angle adjacent (right next to) the angle that measures 107˚. As you can see, it is a supplementary angle because both of them form a straight line, or 180˚.
Therefore,
107+x= 180
x= 180-107
x= 73˚
Next, I will find the measure of the angle that is vertical to the one that measures 107˚. Note that angles that are vertical to each other are always identical, or in other words they have the same measure. Hence, the angle "vertical", or opposite to the one that measures 107˚ has to measure 107˚ as well. You can also tell this is true because they look the same.
Now I'll find the measure of the angle vertical to the one that measures 73˚. As we know, vertical angles are identical, so the one vertical to it is 73˚.
Here, I'll solve for angles 1 and 2. Like I said earlier, when a transversal crosses through 2 parallel lines, there will be 2 sets of angles that all have the same measurements.
To solve for angle 1, simply know what angle is right below it, and that is the one that measures 107˚. (If you look at the 2 lines, you will see that both angle sets are essentially duplicates of each other.) Likewise, angle 2 has to be 73˚ because the one under it is also 73˚.
Angle 1: 107˚
Angle 2: 73˚
QUESTION 8:
Again, we have a transversal that passes through 2 parallel lines. One angle measures 95˚. When there are 3 seperate angles along a straight line, the one next to the one with the given measurement will be the same as that one.
So angle 3 is 95˚. To find angle 4, find the angle measurement that's vertical to angle 3, which is 95˚. Now, since that angle and angle 4 are supplementary (both form a straight line which is always 180˚), 95+x= 180.
(x stands for angle 4)
x+95= 180
x= 180-95
x= 85
Angle 4= 85˚.
QUESTION 9:
ANGLE 5: 49˚
When there is a transversal, there are 2 identical pairs of angles. Therefore, angle 5 must be 49˚.
ANGLE 6: 131˚
angle 5 and angle 6 form a straight line which means they are supplementary angles. Therefore, both angles must add up to 180˚. So 49+x= 180
x= 180-49= 131
(x stands for angle 6)

Honeydew lemons sell in a market place for $24.95 per box. One box contains 9 melons. How much would you have to pay for 17 melons?
Answer:
47.13 for 17 melons
Step-by-step explanation:
We can use a ratio to solve
24.95 x dollars
---------------- = ----------------
9 melons 17 melons
Using cross products
24.95 * 17 = 9x
Divide by 9
24.95 * 17/9 = x
47.127777777 = x
Rounding to the nearest cent
47.13 for 17 melons
Answer:
$47.12
Step-by-step explanation:
We know that 1 box has 9 lemons and each box is $24.95. Therefore, 1 lemon costs 24.95/9 dollars. That leads us to know that 17 lemons cost (24.95/9 * 17). Once we plug that into the calculator and round to the nearest hundreth place, we get $47.12.

⇒12x+x=7
⇒13x=7
⇒x=7/13
3) Solution of an equation 79−3x=12x+19 is
12x+3x=79-19
⇒15x=60
⇒x=4
4) Solution of an equation x²+3=10x−21 is
x²+3=10x−21
⇒ x²-10x+24=0
⇒ x²-6x-4x+24=0
⇒ x(x-6)-4(x-6)=0
⇒ (x-6)(x-4)=0
⇒ x=6 or 4

Dylan and Tiffany each constructed a two-color spinner. Dylan spun his spinner 3 times and calculated that the relative frequency of his spinner landing on blue (0.67) and on red (0.33). Tiffany spun her spinner 200 times and calculated the relative probability of her spinner landing on blue (0.60) and on red (0.40). How can Dylan's and Tiffany's calculations be used to evaluate the fairness of the two spinners?
Answer: You can calculate the likeliness of the spinner landing on blue or red as the more spins you have the more accurate the results would be. In this case, after 200 spins Tiffany calculated that the spinner landing on blue has a 60% chance while landing on red has a 40% chance. Therefore this might not be fair as there is a 60% chance of landing on blue.

How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

O(3,6)
O (3-6)
O(-6, -3)
Answer:
O(3,6)
Step-by-step explanation:
If the points are (-3,-6), this means -3 on the x axis and -6 on the y axis. if it is reflected in the y axis, the coordinates Change from either positive to negative or negative to positive. This means -3 is now 3 and -6 is now 6 hence the coordinates of (3,6)
How do these two equations equal each other? I can't figure it out.
Answer:
These two equations are equal because they both simplify to:
(38x)^(7) = (3222x)^(7) = 3^(7)*2^(7)*2^(7)*x^(7)
and
6^(7)4^(7)x^(7) = (23)^(7)(2^2)^(7)*x^(7) = 2^(7)*3^(7)*2^(14)*x^(7) = 3^(7)*2^(21)*x^(7)
So, we have:
3^(7)*2^(7)*2^(7)*x^(7) = 3^(7)*2^(21)*x^(7)
Cancelling out x^(7) from both sides, we get:
3^(7)*2^(7)*2^(7) = 3^(7)*2^(21)
Simplifying, we get:
2^(7)*2^(7) = 2^(21)
which is true since 2^(7)2^(7) = (2222222)(2222222) = 2^(14), and 2^(21) = (2222222222222)(222222222222*2) = 2^(14)*2^(7).
Answer:
6^(7)4^(7)x^(7) = (23)^(7)(2^2)^(7)*x^(7) = 2^(7)*3^(7)*2^(14)*x^(7) = 3^(7)*2^(21)*x^(7)
3^(7)*2^(7)*2^(7)*x^(7) = 3^(7)*2^(21)*x^(7)
Cancelling out x^(7) from both sides
3^(7)*2^(7)*2^(7) = 3^(7)*2^(21)
Simplified
2^(7)*2^(7) = 2^(21) SLAY
