If parallelogram ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A' lie?
[Hint: Place your coordinates in the blank with no parentheses and a space after the comma in the form: x, y]
Answer:
The point A' lie at (-4,1).
Step-by-step explanation:
From the given figure it is clear that the coordinates of A are (-4,1).
If parallelogram ABCD was reflected over the y-axis, then
[tex](x,y)\rightarrow (-x,y)[/tex]
[tex]A(-4,1)\rightarrow A_1(4,1)[/tex]
Then it reflected over the x-axis,
[tex](x,y)\rightarrow (x,-y)[/tex]
[tex]A_1(4,1)\rightarrow A_2(4,-1)[/tex]
After that, it rotated 180° about the origin,
[tex](x,y)\rightarrow (-x,-y)[/tex]
[tex]A_2(4,-1)\rightarrow A'(-4,1)[/tex]
Therefore the point A' lie at (-4,1).

Graph y−2=−34(x−6) using the point and slope given in the equation.
Use the line tool and select two points on the line.
Answer:
Point-slope form: An equation of a straight line in the form [tex]y -y_1 = m(x -x_1)[/tex];
where
m is the slope of the line and [tex](x_1, y_1)[/tex] are the coordinates of a given point on the line.
Given the equation: [tex]y-2=-\frac{3}{4}(x-6)[/tex] ......[1]
On comparing with Point slope form equation we have;
m = [tex]-\frac{3}{4}[/tex] and point (6 , 2)
Now, find the Intercept of the given equation:
x-intercept: The graph crosses the the x-axis i.e,
Substitute y =0 in [1] and solve for x;
[tex]0-2=-\frac{3}{4}(x-6)[/tex]
[tex]-2=-\frac{3}{4}(x-6)[/tex]
Using distributive property: [tex]a\cdot(b+c) = a\cdot b +a\cdot c[/tex]
[tex]-2 = -\frac{3}{4}x + \frac{18}{4}[/tex]
Subtract [tex]\frac{18}{4}[/tex] on both sides we get;
[tex]-2-\frac{18}{4}= -\frac{3}{4}x + \frac{18}{4} -\frac{18}{4} [/tex]
Simplify:
[tex]-\frac{26}{4} = -\frac{3}{4}x[/tex]
or
-26 = -3x
Divide both sides by -3 we get;
x = 8.667
x-intercept: (8.667, 0)
Similarly, for
y-intercept:
Substitute x = 0 in [1] and solve for y;
[tex]y-2=-\frac{3}{4}(0-6)[/tex]
[tex]y-2=\frac{18}{4}[/tex]
Add 2 on both sides we get;
[tex]y-2+2=\frac{18}{4}+2[/tex]
Simplify:
[tex]y=\frac{26}{4} =6.5[/tex]
y-intercept: (0, 6.5)
Now, using these two points (8.667, 0) and (0, 6.5) you can plot the graph using line tool as shown below.
Product of nine and the sum of a number Z and four
The product of nine and the sum of a number Z and four can be written as 9(Z + 4). For example, if Z = 5, then the expression becomes 9(5 + 4), which equals 81.
Explanation:The product of nine and the sum of a number Z and four can be written as 9(Z + 4).
For example, if Z = 5, then the expression becomes 9(5 + 4), which equals 9(9) = 81.
So, the product of nine and the sum of a number Z and four is 9(Z + 4), where Z represents any number.

Jessica is filling glasses with water. Each glass holds 3/5 cup of water. She pours 4 1/5 cups of water into the glasses.
How many glasses does she fill with water?
7 cups
4 1/5= 21/5
3+3+3+3+3+3+3= 21
7
Jessica can fill 7 glasses with water, by dividing the total amount of water ([tex]4\frac{1}{5}[/tex] cups) by the amount that each glass holds ([tex]\frac{3}{5}[/tex] cup).
The question asks us to determine how many glasses Jessica can fill with water when each glass holds [tex]\frac{3}{5}[/tex] cup of water and she has 4 1/5 cups of water in total. To solve this, we need to divide the total amount of water by the amount each glass holds.
Firstly, we need to convert the mixed number 4 1/5 cups to an improper fraction. This is done by multiplying the whole number by the denominator and adding the numerator, like this: (4 times 5) + 1 = 21, so 4 1/5 cups is the same as [tex]\frac{21}{5}[/tex]cups.
Next, we divide the total amount of water (21/5 cups) by the amount each glass holds ([tex]\frac{3}{5}[/tex] cup), which can be written as a fraction division problem:
[tex]\frac{\frac{21}{5} }{\frac{3}{5} }[/tex] = [tex]\frac{21}{5}[/tex] x [tex]\frac{5}{3}[/tex] = [tex]\frac{21}{3}[/tex] = 7
So, Jessica can fill 7 glasses with water.

Melvin and Sylvia are married with no children, and they're filing their federal income tax return. Melvin had a gross income of $44,500 last year, while Sylvia had a gross income of $51,200, and they plan to use the standard deduction. They're trying to decide whether to file their return jointly or separately, so they want to calculate how much less they would pay in federal income taxes if they filed jointly rather than separately.
Part I: When filing separately, both Melvin and Sylvia have a standard deduction of $5700, and each can claim him/herself as an exemption for $3650. Neither has any additional adjustments to income. What is Melvin's taxable income? How about Sylvia's taxable income?
add standard deduction and exemption: 5700 + 3650 = 9350
subtract from each of their incomes and that will be the taxable income:
Melvin: 44500 - 9350 = 35150 taxable income
Sylvia: 51200 - 9350 = 41850 taxable income
Melvin's taxable income is $34,150 and Sylvia's taxable income is $42,850.
Explanation:To calculate Melvin's taxable income, we need to subtract his standard deduction and exemption from his gross income. Melvin's gross income was $44,500 and his standard deduction is $5700. He can also claim himself as an exemption for $3650. Therefore, Melvin's taxable income would be $44,500 - ($5700 + $3650) = $34,150.
In a similar way, to calculate Sylvia's taxable income, we subtract her standard deduction and exemption from her gross income. Sylvia's gross income was $51,200 and her standard deduction is $5700. She can also claim herself as an exemption for $3650. Therefore, Sylvia's taxable income would be $51,200 - ($5700 + $3650) = $42,850.

how do you do a 4 pound bag of sugar contains 454 one teaspoon servings and cost 3.49. A batch of muffins uses 3/4 cups of sugar. How many batches can you make if you use all the sugar what is the cost of sugar each
The number of batches you can make if you use all the sugar is 12.61 batches.
The cost of sugar used per batch is $0.28.
How many batches can you make if you use all the sugar?A 4-pound bag of sugar = 454 one-teaspoon
Sugar used for a batch of muffins = ¾ cup
If 1 cup = 48 teaspoons
3/4 cup = 3/4 × 48
= 36 teaspoons
Number of batches to make = 454 one-teaspoon / 36 teaspoons
= 12.61 batches
Cost of sugar teaspoons= 3.49/454
= $0.007687224669603 per teaspoon
Cost of sugar per batch = 0.007687224669603 × 36
= $0.276740088105726 per batch
Hence, the cost of sugar used per batch is approximately $0.28

A 4-pound bag of sugar contains 454 one-teaspoon servings and costs $3.49. A batch of muffins uses ¾ cup of sugar. How many batches can you make if you use all the sugar? What is the cost of sugar for each batch? (1 cup = 48 teaspoons)
To find out how many batches of muffins can be made and the cost per batch, convert the total servings of sugar to cups, then divide by the amount of sugar used per batch, and finally, divide the total cost by the number of batches. which results in approximately $0.29 per batch.
The subject of this question is Mathematics, and it appears to be at the High School level due to the application of ratios, conversions, and basic algebraic skills to solve real-world problems.
Calculating Batches of Muffins from a Sugar Bag
Firstly, we determine the total amount of sugar in the bag in terms of cups. Since 1 teaspoon is equivalent to 4 grams of sugar, and we have 454 servings, we multiply 454 by 4g to get 1816g of sugar in total. To convert grams to cups (given 1 cup of sugar is 200g), we divide 1816g by 200g/cup, which gives us 9.08 cups.
Since a batch of muffins uses 3/4 cup of sugar, we divide the total cups of sugar by 3/4 to find the number of batches. 9.08 cups divided by 3/4 cups per batch results in approximately 12.1 batches; however, since you can't make a partial batch with the remaining sugar, it is safe to say you can make 12 full batches. To find the cost per batch, divide the total cost of the bag ($3.49) by the number of batches (12), which results in approximately $0.29 per batch.
