Answer: C,E
Step-by-step explanation: This is because when we plug in 5 for x and for y in the first inequality we get.
-3(5)-5>-4
Which equals -20>-4 and thats false so thats not it.
Then we got to (2,6) and we plug 2 for x and 6 for y and get:
-3(2)-6>-4
Which is -12>-4 which is false so thats also not it.
Then we got to C and we plug in -4 for x and 1 for y and we get:
-3(-4)-1>-4 and we get 12-1>-4
This is correct so we plug it in to the next inequality and get:
2(-4)-1<-2 and we get -9<-2 which is true
So C is an answer and we go on to d and e
For d we plug in 6 for x and 5 for y and we get:
-3(6)-5>-4 which is -23>-4 which is false so its not d
And then we go to e which is -5 for x and 0 for y and we plug in and we get:
-3(-5)-0>-4 This is 15>-4 which is true so we go to the next inequality and we plug in -5 for x and 0 for y and we get:
2(-5)-5(0)<-2 This is -10<-2 which is true so e is the other answer so the answers are

We can split the figure into two rectangles. Rectangle 1 will have an area of 2*3=6. Rectangle 2 will have an area of 2*5=10
10+6=16
HOPE THIS HELPS!!!!!!!!Which is an equation of the line through (-8,-4) and (4, 5)?
Answer:
the right answer is A :)
a rectangle is 16 feet long and 8 feet wide find its area
The area of the rectangle is 128 square feet.
To find the area of a rectangle, you multiply the length by the width. In this case, the rectangle is 16 feet long and 8 feet wide.
Area = Length * Width
Substituting the given values:
Area = 16 feet * 8 feet
To perform the calculation, multiply the numbers:
Area = 128 square feet
Therefore, the area of the rectangle is 128 square feet.
The area of a rectangle represents the total amount of space enclosed within its boundaries. In this case, the rectangle measures 16 feet in length and 8 feet in width, so the area is calculated as 16 feet multiplied by 8 feet, resulting in 128 square feet.
The concept of area is fundamental in geometry and is used to measure the size of two-dimensional shapes. In the case of a rectangle, the area represents the product of its length and width, as every point within the rectangle contributes to its overall size.
Knowing the area of a rectangle can be useful in various situations. For example, if you want to determine how much flooring material is required to cover a rectangular room, you would need to know the area of the floor.

!!!Please help will give the brainliest, and please do not put in a silly answer because you want some points or I will report you!!! What are the properties of a kite, trapezoid, square, rectangle, parallelogram, rhombus?
Answer:
In short, they are all quadrilaterals.
Step-by-step explanation:
Rectangle:
- Every angle equals 90 degrees
- Opposite sides are equal and parallel
Square:
- Every angle equals 90 degrees
- Opposite sides are equal and parallel
- Diagonals within the square are perpendicular
Parallelogram:
- Opposite sides are equal and parallel
- Opposite angles are equal
- Any two angles next to each other have to equal 180 degrees, since it would be a line
Rhombus:
- Opposite angles are equal
- All sides are equal
- Opposite sides are parallel
- Diagonals within the square are perpendicular
- Any two angles next to each other have to equal 180 degrees, since it would be a line
Trapedzoid:
- There is only one pair of parallel lines
Kite:
- There are two pairs of equal signs
- There are two equal angles
- You can look at it like two equal triangles glued together

(50pts) The distance covered and the time taken by a car are plotted in a graph.
a. Find the slope of the line in the graph.
b. Calculate the distance traveled by the car at the 20th second.
c. Calculate the speed of the car.
Answer:
a=2
b=40m
c=2m/s
Step-by-step explanation:
slope is rise over run so 10/5 simplified is 2/1 or 2
for b just look at the graph at the 20th second
for c you do distance over time so basically the same thing as a 10/5 which is 2m/s

It is one more than the sum of the first three natural numbers, followed by the 24th letter of the alphabet. Please help
Answer:
The set of natural numbers is the set of all positive integers, then this set is:
{1, 2, 3, ...}
and the 24th letter of the alphabet is x
Now we want to write the expression given in the sentence "It is one more than the sum of the first three natural numbers, followed by the 24th letter of the alphabet"
We can "break" this in parts, so it is easier to understand.
Then:
"...the sum of the first 3 natural numbers..."
is:
1 + 2 + 3
Then:
"...the sum of the first 3 natural numbers, followed by the 24th letter of the alphabet"
This can be written as:
(1 + 2 + 3) + x
Now we can analyze the complete sentence:
"It is one more than the sum of the first three natural numbers, followed by the 24th letter of the alphabet"
This is equal to the expression we found above plus one, then we can write this as:
[(1 + 2 + 3) + x] + 1
[6 + x] + 1
6 + x + 1
7 + x
In Orlando Florida the high temperature was 85 degrees Fahrenheit on Saturday and 79 degrees Fahrenheit on Sunday what is the percent of change in the high temperature from Saturday to Sunday to the nearest whole percent
Answer:
[tex]7\%[/tex]
Step-by-step explanation:
Initial temperature = 85 degrees Fahrenheit
Final temperature = 79 degrees Fahrenheit
Percentage change in temperature is given by
[tex]\dfrac{|\text{Final temperature}-\text{Initial temperature}|}{\text{Initial temperature}}\times 100\%\\ =\dfrac{|79-85|}{85}\times 100\%\\ =7.05\approx 7\%[/tex]
The change in the high temperature from Saturday to Sunday is [tex]7\%[/tex].
Lamar needs to buy some pencils. Brand A has a pack of 18 pencils for 2.36 . Brand B has a pack of pencils 24 for 4.09 Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.
Answer:
The unit price of brant A and brand B is 0.1311 and 0.1704 and brand A would be better
Step-by-step explanation:
The computation of the unit price for each brand is shown below:
For brand A, the unit price is
= 2.36 ÷ 18 pencils
= 0.1311
For Brand b, the unit price is
= 4.09 ÷ 24
= 0.1704
So here as we can see that brand A would be better as it has less cost as compared with brand B
