The coordinates of the vertices for the figure HIJK are H(0, 5), I(3, 3), J(4, –1), and K(1, 1).
To determine if it is a parallelogram, use the converse of the parallelogram diagonal theorem. This states that if the diagonals , then the quadrilateral is a parallelogram.
The midpoint of HJ is and the midpoint of IK is (2, 2).
Therefore, HIJK is a parallelogram because the diagonals , which means they bisect each other.
Answer: The quadrilateral HIJK is a parallelogram.
Explanation:
It is given that the coordinates of the vertices for the figure HIJK are H(0, 5), I(3, 3), J(4, –1), and K(1, 1).
The parallelogram diagonal theorem states that the quadrilateral is a parallelogram if both diagonal bisects each other.
If HIJK is a quadrilateral, then HJ and IK are the diagonals of HIJK.
First we find the midpoint of HJ.
[tex]\text{Midpoint of HJ}=(\frac{0+4}{2}, \frac{5-1}{2})[/tex]
[tex]\text{Midpoint of HJ}=(2,2)[/tex]
Now, find the midpoint of IK.
[tex]\text{Midpoint of IK}=(\frac{3+1}{2}, \frac{3+1}{2})[/tex]
[tex]\text{Midpoint of IK}=(2,2)[/tex]
The midpoint of both diagonal are same. It means the diagonals of HIJK bisects each other.
By parallelogram diagonal theorem, we can say that the quadrilateral HIJK is a parallelogram.
Answer: IH = IJ = 3 and JK = HK = StartRoot 29 EndRoot, and IH ≠ JK and IJ ≠ HK.

what is 2/3x+4=4/5x-2
Hey there!
Apply fraction cross multiply: if a/b = c/d , then a *d = b*c
2 ( 5x - 2 ) = ( 2x + 4 ) * 4
expand : 2 (5x-2 ) => 2*5x - 2*2 => 10x - 4
expand : ( 2x +4 ) * 4 => 2x * 4 + 4*4 => 8x + 16
10x - 4 = 8x+16
add 4 to both sides:
10x-4+4 = 8x+16+4
simplify :
10x = 8x + 20
subtract 8x from both sides:
10x -8x = 8x+20-8x
simplify:
2x = 20
Therefore:
x = 20 / 2
x = 10
Hope that helps!
Step 1. Simplify 2/3x to 2x/3
2x/3 + 4 = 4/5x - 2
Step 2. Simplify 4/5x to 4x/5
2x/3 + 4 = 4x/5 - 2
Step 3. Multiply both sides by 15 (the LCM of 3,5)
10x + 60 = 12x - 30
Step 4. Subtract 10x from both sides
60 = 12x - 30 - 10x
Step 5. Simplify 12x - 30 - 10x to 2x - 30
60 =2x - 30
Step 6. Add 30 to both sides
60 + 30 =2x
Step 7. Simplify 60 + 30 to 90
90 = 2x
Step 8. Divide both sides by 2
90/2 = x
Step 9. Simplify 90/2 to 45
45 = x
Step 10. Switch sides
x = 45

Polygon ABCD is translated to create polygon A’B’C’D’. Point A is located at (1,5) and point A’ is located at (-2,3). Which expression defines the transformation of any point (x,y) to (x’,y’) on the polygons?
Answer:
The translation is 3 units left and 2 units down
Step-by-step explanation:
we know that
Point A is located at (1,5) and point A’ is located at (-2,3)
so
The rule of the translation is
(x,y) -----> (x+a,y+b)
(1,5) ----> (-2,3)
Find the values of a and b
1+a=-2 ----> a=-2-1 ----> a=-3
5+b=3 ----> b=3-5 ----> b=-2
so
The rule of the translation is
(x,y) -----> (x-3,y-2)
That means -----> The translation is 3 units left and 2 units down
Answer:
x’ = x - 3
y’ = y - 2

9.1÷3576 rounded to the nearest whole number
Answer:
Answer is 0
Step-by-step explanation:
[tex]\frac{9.1}{3576}=0.0025447427[/tex]
Whole numbers are the set of numbers represented by {0,1,2,3.......}, So basically counting numbers with a 0. Whole numbers does not contain fractions or negative numbers.
Rounding off is a way of simplifying a number so that it is close to the value of the original number. 0.0025447427 lies in between the whole number 0 and 1. But is is a very small value and is close to 0 than 1. So the closet whole number is 0.
Bi-weekly mortgage is $576. Monthly phone charges are $44.95. The electric bill last month was $105.88. Groceries cost about $98/week. What is a good estimate of your monthly expenses?
Final answer:
To estimate the monthly expenses, we calculate each monthly cost including the bi-weekly mortgage paid twice a month, phone charges, electric bill, and groceries multiplied by the average number of weeks per month for a total of $1,728.64.
Explanation:
To estimate the monthly expenses based on the provided costs, we need to calculate the monthly totals of each category. Here's the breakdown:
Bi-weekly mortgage: Since a month roughly consists of 4 weeks, a bi-weekly amount would be paid twice. Therefore, $576 × 2 = $1,152 for the mortgage per month.
Monthly phone charges: This cost is already on a monthly basis, so it's $44.95 for the phone.
Electric bill: The electric bill from last month was $105.88 and we'll use this as an estimate for the current month as well.
Groceries: Groceries cost about $98/week. As there are roughly 4.345 weeks in a month (52 weeks in a year divided by 12 months), we'll multiply the weekly cost by this factor: $98 × 4.345 ≈ $425.81 for groceries.
Adding these expenses, the total estimated monthly expenses would be $1,152 (mortgage) + $44.95 (phone) + $105.88 (electric) + $425.81 (groceries) = $1,728.64.

The price of a used car is reduced by 25% to $6,000. What was the original price of the car in dollars? Round your answer to the nearest dollar.
The original price of the used car, before the 25% reduction, was approximately $8,000. This was calculated by considering that $6,000 represents 75% of the original price.
Explanation:The question is related to percentage and price, which falls under the realm of Mathematics. To find the original price of the car, you must consider that the price after the 25% discount was $6,000. This 25% reduction means that $6,000 represents 75% of the original price because 100% - 25% equals 75%. To find the original price (which is 100%), you can set up a simple equation and solve for the original price using cross multiplication. The equation will look like this:
75/100 = 6000/x
When you cross multiply and solve for x, the result is $8,000. So, the original price of the car was approximately $8,000.

Final answer:
The total area when the two given areas are added together, after converting them into the same unit (square meters), is 17,078,004 m².
Explanation:
The student is asking to perform an addition of two figures that represent areas in different units (square kilometers, hectares, and square meters). To solve this, we need to convert all the areas to the same unit, for instance, square meters (m²), and then add them together. Here's the conversion and addition step-by-step:
Convert 5 square kilometers (sq.km) to square meters: 5 sq.km = 5 × (1,000²) = 5,000,000 m².
Convert 95 hectares (ha) to square meters: 95 ha = 95 × 10,000 = 950,000 m².
Add the square meters: 5,000,000 m² + 950,000 m² + 8,994 m² = 5,958,994 m².
For the second area, convert 11 sq.km to m²: 11 sq.km = 11 × (1,000²) = 11,000,000 m².
Convert 11 ha to m²: 11 ha = 11 × 10,000 = 110,000 m².
Add the square meters: 11,000,000 m² + 110,000 m² + 9,010 m² = 11,119,010 m².
Finally, add the two total areas in m²: 5,958,994 m² + 11,119,010 m² = 17,078,004 m².

4.What are the coordinates of the vertex of y = –x2 – 12x – 32?
5.What's the y-intercept of y = –x2 – 12x – 32?
6.Find any zeros of y = –x2 – 12x – 32.
Question 1:
For this case we have:
The value of the x coordinate of the vertex is with the equation given by:
[tex]x = -\frac{b}{2a} \\[/tex]
Where b = -12 and a = -1
therefore,
[tex]x =- \frac{-12}{2(-1)} \\\\x = -6\\[/tex]
To find the coordinate and substitute in the equation:
[tex]y = - (- 6) ^ 2-12 (-6) -32\\\\y = 4\\[/tex]
Answer:
The coordinates of the vertex are (-6.4)
Question 2:
For this case we have the following equation:
[tex]y = -x ^ 2 - 12x - 32\\[/tex]
By definition, to find the intercept point with the y axis, we make x = 0 and substitute as shown below:
[tex]y = - (0) ^ 2-12 (0) -32\\\\y = -32\\[/tex]
Thus, the intercept point with the y axis is given by (0, -32)
Answer:
the y-intercept is (0, -32)
Question 3:
For this case we have the following equation:
[tex]y = -x ^ 2 - 12x - 32\\[/tex]
The zeros of the function are given by the cut points with the x axis, so, equaling the equation to zero and clearing x we have:
[tex]0 = -x ^ 2 - 12x - 32\\[/tex]
Rewriting the equation we have:
[tex]0 = x ^ 2 + 12x +32\\[/tex]
Factoring has the following:
[tex](x + 4) (x + 8) = 0\\[/tex]
Thus, the solutions are given by:
[tex]x = -4 \\\\x = -8\\[/tex]
Therefore, the zeros of the equation are (-4.0) and (-8.0)
Answer:
(-4.0) and (-8.0)

The formula for the surface area S of a rectangular prism is S=2hl+2hw+2lw, where l is the length,w is the width, and h is the height. Solve the formula for height h.
Hey there!!
Equation given :
S = 2hl + 2hw + 2lw
... S = 2 ( hl + hw + lw )
S / 2 = hl + hw + lw
S / 2 = h ( l + w ) + lw
S / 2 - lw = h ( l + w )
S - 2lw / 2 = h ( l + w )
( S - 2lw / 2 ) / ( l + w ) = h
( S - 2lw / 2l + 2w ) = h
[tex]\frac{S-2lw}{2l+2w} = h[/tex]
Hope my answer helps!!
To solve the formula S=2hl+2hw+2lw for h, rearrange the formula using basic algebra. The final formula for h is h = (S - 2lw) / (2l + 2w).
Explanation:The formula for the surface area S of a rectangular prism is S=2hl+2hw+2lw, where l is the length,w is the width, and h is the height. To solve this formula for height h, the formula needs to be rearranged with basic algebra.
Start by subtracting 2lw from both sides of the equation, which leaves us with S - 2lw = 2hl + 2hw. Then, factor out the h from the right side of the equation, you get S - 2lw = h(2l + 2w).
Finally, to solve for h, divide both sides of the equation by (2l + 2w). The final formula to solve for height h would be h = (S - 2lw) / (2l + 2w).

what is a transformation that shrinks or stretches a figure
A dilation is a transformation that shrinks or stretches a figure by multiplying or dividing each point by a scale factor.
Explanation:A transformation that shrinks or stretches a figure is called a dilation. A dilation is a transformation that changes the size of the figure without changing its shape. It can either shrink the figure, making it smaller, or stretch it, making it larger.
During a dilation, each point of the figure is multiplied or divided by a scale factor. If the scale factor is greater than 1, the figure is stretched. If the scale factor is between 0 and 1, the figure is shrunk.
For example, if we have a triangle and apply a dilation with a scale factor of 2, each side of the triangle will be multiplied by 2, resulting in a larger triangle.
