The coordinates of vertex E of parallelogram DEFG is: (-3, 3).
What does a midpoint mean?Midpoint, as the word suggests, means the point which lies in the middle of something. Midpoint of a line segment means a point which lies in the mid of the given line segment.
Diagonals of a parallelogram bisects each other, meaning they divide each other into equal parts.
The given vertices of parallelogram DEFG are:
D(-2, – 4),F(0,7), and G(1,0)
Let (x, y) = coordinates of vertex E.
Find the coordinates of E
Find midpoint of D(-4, - 2) and F(3, 3) using :
[tex](\dfrac{-2+0}{2}, \dfrac{-4 + 7}{2}) = ( \dfrac{x + 1}{2}, \dfrac{y + 0}{2})[/tex]
[tex](-2, 3) = (x + 1, y)[/tex]
By comparison So, we have:
-2 = x + 1
x = -3
and
y = 3
Therefore, the coordinates of vertex E is: (-3, 3).

Paul has a sum of $260 in $5 and $10 bills. If he has 40 bills in total, how many were of each denomination?
Answer:
28 5 dollar bills
12 10 dollar bills
Step-by-step explanation:
You can write two equations to model this situation'
x will be the number of 5 dollar bills
y will be the number of 10 dollar bills
x+y=40
5x+10y=260
There are a couple of ways you can solve this but but I will be doing it through substitution because that looks easier (I can explain other methods if you're interested)
So we have x+y=40
If I subtract y from both sides and divide by -1 we get
-x+40=y
We can then plug this value in for y in the second equation
5x+10(-x+40)=260
Distribute the 10 and combine like terms to get
-5x+400=260
subtract 400 from both sides and divide by -5 to get
x=28
This means that there are 28 5 dollar bills. We can plug this value back in for x into our first equation to solve for y
28+y=40
Subtract 28 from both sides
y=12
This means that there were a total of 28 5 dollar bills and 12 10s
I doubled checked this in desmos and it checks out
9x-3x-5=19 solve for x
Answer: x=4
Step-by-step explanation:
Simplify the left side of 9x-3x-5=19 by combining like terms:
6x-5=19
Add 5 to both sides:
(6x-5)+5=19+5
Simplify:
6x=24
Divide both sides by 6:
(6x)/6=24/6
Simplify:
x=4
Jeremiah plans on building a 5 meter long garden walkway that is paved with square stones that measure " $ meter on each side. There will be no spaces between the stones. How many stones will be needed to complete the garden walkway?
Complete question :
Jeremiah plans on building a 5 meter long garden walkway that is paved with square stones that measure " 5/6 meter on each side. There will be no spaces between the stones. How many stones will be needed to complete the garden walkway?
Answer:
12
Step-by-step explanation:
Given that:
Length of square block to be used = 5/6 meters
Length of garden. Walkway = 5 m
Since length of walkway is the same on both sides, then the Total length = 5m + 5m = 10 meters
Number of square stones required :
Total length of walkway / side length of stones to be used
= 10 meters ÷ (5/6) meters
= 10 * 6/5
= 60 / 5
= 12 stones

There are 124 pages in a sketchbook. John used 36 pages. Miss Hamilton asks him to draw 2 pictures each week. How many weeks does John take to finish the sketchbook? Step by step explanation pls.
Answer:
44 weeks
Step-by-step explanation:
First, he’s already used 36 pages so he has 124-36=88 pages left to use.
Since he can use 2 pages per week, by dividing 88(# of pages left) by 2( pages per week), you will get the answer. 88÷2=44 weeks

Hello!
[tex]slope = 2\\\\y-intercept = (0, 3)\\\\Equation: y = 2x + 3[/tex]
We can find the slope using the slope formula:
[tex]slope = \frac{y_{2} - y_{1}}{x_{2}-x_{1}}[/tex]
Plug in any two points from the table. We can use (0, 3) and (1, 5):
[tex]slope = \frac{5 - 3}{1-0}[/tex]
[tex]slope = 2[/tex]
Now, we can find the y-intercept by finding the y-value at which x = 0.
According to the table, when x = 0, y = 3. Thus, the y-intercept is:
[tex](0, 3)[/tex]
We can write an equation using the slope and y-intercept in the format
y = mx + b where "m" is the slope and "b" is the y-intercept.
Plug in the solved values into the equation:
y = 2x + 3.

Sharon is 5 times as old as her daughter. 4 years ago, the square of the sum of their ages is equal to 256. Forming an algebraic equation, find their present ages.
Answer:
Sharon is 36
Her daughter is 7 years and 2 months
Step-by-step explanation:
sharon is 5× as old
her daughter is written as 1 (because we dont know about her age)
then square root of 256 to find square which is equal as said in the queston:which is 16
algebraic equation would be:5n+16 (n represents the years and 5 is how many times older sharon is and 16 is how old their square sum of agewas 4 years ago)
Their present age would be:
Sharon=5x4+16=36
Daughter =36÷5=7 years 2 months
The present age of Sharon is 20 and the Present age of her daughter is 4.
What are algebraic equations?A mathematical statement in which two expressions are rendered equal to one another is known as an algebraic equation. A variable, coefficients, and constants make up an algebraic equation in most cases.
Given, Sharon is five times her daughter's age. The square of their ages was equal to 256 four years ago. Let the age of Sharon is x and the age of her daughter be y.
Thus the algebraic equation formed as per the given data is,
x = 5*y (Present age)
(x-4 + y -4)^2 = 256 (Four years ago)
Taking square root both the sides
x + y = 24
comparing both equations
5 y + y = 24
y = 4
and x = 20
Therefore, Sharon is currently twenty years old, and her daughter is currently four years old.

which algebra tiles are used in this equation:
4x + 7 = 23
Answer:
4x+7=23
4.4+7=23
Step-by-step explanation:
23-7=16
16/4=4
The algebra tiles used in the equation 4x + 7 = 23 are four x-tiles, seven unit tiles, and 23 unit tiles.
To model the equation 4x + 7 = 23 using algebra tiles, we would use variable tiles (x-tiles) and unit tiles.
For the term 4x, we would use four x-tiles since the coefficient is 4.
For the term 7, we would use seven unit tiles since it is a constant.
The equal sign (=) does not have a specific tile representation; it simply indicates the equation's balance.
On the other side of the equation, for the term 23, we would represent it using 23 unit tiles.
So, the algebra tiles used in this equation would be four x-tiles, seven unit tiles, and 23 unit tiles.

The radius of the base of a cylinder is decreasing at a rate of 121212 kilometers per second. The height of the cylinder is fixed at 2.52.52, point, 5 kilometers. At a certain instant, the radius is 404040 kilometers. What is the rate of change of the volume of the cylinder at that instant (in cubic kilometers per second)
Answer:
7536 [tex]km^3/sec[/tex]
Step-by-step explanation:
Given that:
Rate of decreasing of radius = 12 km/sec
Height of cylinder is fixed at = 2.5 km
Radius of cylinder = 40 km
To find:
The rate of change of Volume of the cylinder?
Solution:
First of all, let us have a look at the formula for volume of a cylinder.
[tex]Volume = \pi r^2h[/tex]
Where [tex]r[/tex] is the radius and
[tex]h[/tex] is the height of cylinder.
As per question statement:
[tex]r[/tex] = 40 km (variable)
[tex]h[/tex] = 2.5 (constant)
[tex]\dfrac{dV}{dt} = \dfrac{d}{dt}\pi r^2h[/tex]
As [tex]\pi, h[/tex] are constant:

Required
Fill in the gaps
(a) The equation
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
From the table, we can say that:
[tex](x_1,y_1) = (0,-300)[/tex]
[tex](x_2,y_2) = (300,0)[/tex]
So, we have:
[tex]m = \frac{0 -(-300)}{300 - 0}[/tex]
[tex]m = \frac{0 +300}{300}[/tex]
[tex]m = \frac{300}{300}[/tex]
[tex]m = 1[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - (-300) = 1(x - 0)[/tex]
[tex]y +300 = 1(x)[/tex]
[tex]y +300 = x[/tex]
[tex]y= x - 300[/tex]
(b) When x = 54
Substitute 54 for x in [tex]y= x - 300[/tex]
[tex]y = 54 - 300[/tex]
[tex]y = -246[/tex]
