Answer:
20 units²
Step-by-step explanation:
We can split the polygon into two triangles along the x-axis.
To work out the area of the top triangle, we can do 1/2 × b × h → a = 1/2 × 4 × 4 = 8 units²
To work out the area of the bottom triangle, we can do 1/2 × b × h → a = 1/2 × 4 × 6 = 12 units²
8 + 12 = 20 units²
Hope this helps!

When answering equations that contain abolute values do I answer with the absolute value symbols ?
for example |-44| + |-34| do I answer with |-78| or 78 or |78|
Answers
Answer:
78
Step-by-step explanation:
|-44| + |-34|
Using absolute values
|-44| = 44
|-34| = 34

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
Answers
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

a rectangle that is 30 inches long and 10 inches wide can be divided into two congruent squares. True or false?

To split the rectangle into 2 parts, you can go one of two ways. One way would make the parts 15" by 10", and the other way would make the two parts 30" by 5". Neither way is equal on all sides, which means neither one is a square. That would make the statement false.

What is the sum of the angle measures in this shape?
A) 180∘
B) 540∘
C) 720∘
D) 360∘
Answers
Answer:
B) 540
Step-by-step explanation:
To find the sum of interior angles of a polygon, we can use the following formula:
(n-2)·180, where n is the number of sides the polygon has.
In this case, this polygon has 5 sides, which makes it a pentagon.
(n-2)·180
substitute
(5-2)·180
simplify
3·180
=540
So, the total sum is 540°.
Hope this helps! :)
Answer: B) 540 degrees
Step-by-step explanation:
The formula for interior angles of a polygon is 180(n-2). N is the number of sides.
Plug the given values into the equation:
180(5-2)=180*3=540
The sum of exterior angles of any polygon is 360 degrees. This problem didn't specify, so I would assume it's talking about interior angles, so the answer would be 540 degrees.

The point (-4,1) is rotated 180 degrees counterclockwise using center (-3,0). What are the coordinates of the image?
(my teacher didn't include an image so im sorry if you were wanting one)
A. (-4, -1)
B. (-5, -2)
C. (-2, -1)
D. (4, -1)
Answers
Answer:
C. (-2, -1)
Step-by-step explanation:
It can help to plot the points.
For rotation 180 degrees, the center of rotation is the midpoint of the segment joining the given point and its image. That means you want to find the other end of a segment with one end (-4, 1) and midpoint (-3, 0).
For center of rotation O, this means ...
O = (A +A')/2
2O -A = A'
A' = 2(-3, 0) -(-4, 1) = (-6+4, 0 -1) = (-2, -1)
The coordinates of the image are (-2, -1).
Evander would like to buy a new hockey stick. He earns $15 time he cuts the grass in his neighborhood. Because of his busy schedule, he can cut grass on Saturdays and Sundays. Evander is responsible for paying $10/week toward his cell phone bill. He also enjoys chocolate and has a $2 bar least twice weekly. Every time he cuts two lawns, he has to fill up the lawnmower with $5 worth of gas.
If he cuts one lawn each day on the weekend, how much money will he have after he has paid for gas, chocolate, and his cell phone?
Evander would like the same stick that Alexander Ovechkin uses. The regular price is $229.99 (including taxes). How long will it take Evander to save enough money to buy the stick?
When could Evander save enough for the stick if he stopped eating chocolate bars?
When could Evander save enough for the stick if he was able to cut another lawn on Wednesday nights AND stopped eating chocolate?
Answers
Answer/Step-by-step explanation:
If he cuts one lawn each day on the weekend, how much money will he have after he has paid for gas, chocolate, and his cell phone?
earns - 30 pays - $10pb $2b $5(this is for the 2 days)
SO he gets 30 but spends 19,
Meaning he gets $11 proffit.
30-19 = $11
Evander would like the same stick that Alexander Ovechkin uses. The regular price is $229.99 (including taxes). How long will it take Evander to save enough money to buy the stick?
He makes $11 every week. so 229.99/11 = 20.9, so it will take him 21 weeks to get it.
When could Evander save enough for the stick if he stopped eating chocolate bars?
Ok so he would be getting 2 dollars more so that would make it $13. So 229.99/13 = 17.69, meaning it will take 18 weeks to get it.
For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
