Three students each examine the system of linear equations shown.
8x+4y=16
8x+2y=8
Caleb says there is exactly one solution. Jeremy says there is no solution. Kim says there are infinitely many solutions.
Answer:
The solution is (0, 4), and there is only one solution
Step-by-step explanation:
Let's actually solve the system if that's possible. Solving the second equation for 8x, we get 8x = 8 - 2y. Substituting this result into the first equation eliminates y:
8 - 2y + 4y = 16,
which simplifies to 2y = 8 and then y = 4.
Substituting 4 for y in the second equation yields 8x + 2(4) = 8, so we can quickly deduce that x = 0.
The solution is (0, 4), and there is only one solution
what is the volume of this prisim 1 cm cubed
2 cm cubed
4 cm cubed
8 cm cubed
Hey there hope you are having A great day!
4x1x1/2 =2 to find the volume you must multiply all sides of your recangular prism. so... 4x1=4 4x1/2 = 2 hop this helps.
In case i wasnt clear, your answer is 2
Jasmine unfolded a cardboard box. The figure of the unfolded box is shown below:
A long rectangle divided along the length into 4 equal squares is shown. Along the upper edge length of the second square is shown another square, and along the lower edge length of the fourth square is shown another square. The first square from the left has two adjacent sides labeled as 2 inches each.
Which expression can be used to calculate the area of cardboard, in square inches, that was used to make the box?

The area of the square
= 5 * 5
= 25 sq. in
The area of each triangle
= 7 * 5 / 2
= 17.5 sq. in
The total surface area of the square pyramid
= (25 + 17.5*4) sq. in
= 95 sq. in

What number would you divide by in order to simplify the following fraction to its simplest form?
8/20
Answer: You would divide the fraction by 4/4.
Step-by-step explanation: First, you would assemble the fraction correctly, and then you would put 4/4 next to 8/20 and divide like
8/20 divided by 4/4. you would divide regularly and you would get the answer 2/5. You would use the number 4 because 4 is the GCF of 8 and 20. 4/4 is equal to one and any number divided by one is the same number.
Answer:
4
Step-by-step explanation:
8/20
8/4=2
20/2=5

Samedy says that the total number of brothers and sisters that the class has is 24, because there will be 24 dots above the number line on the line plot. Use the drop-down menus to complete the statement below.
Is Samedy's statement true or false?
In total, the class has _____ brothers and sisters?
Answer:
Samdy's statement is FALSE, total number of brothers and sisters is 52
Step-by-step explanation:
To organize our information we should draw a table, where group the students by how many siblings they have, and then calculate the total number of siblings.
How do i Solve this?
Answer:
A=54.45
Step-by-step explanation:
You want to solve for the area in 2 parts. First I solved for the rectangle.
Area of a rectangle: A=lw
This means 9×3=27
Then I solved for the area of the triangle.
Area of a triangle: 1/2bh
This means 1/2(9×6.1)⇒1/2(54.9)=27.45
Then you add the area of the triangle and the areo of the rectangle together:
27.45+27=54.45

Difference between equilateral isosceles and scalene triangle
Answer:
the difference is that a scalene triangle has no congruent sides, isosceles triangles have 2 congruent sides, and equilateral triangles have 3 congruent sides.
Answer:
See below ~
Step-by-step explanation:
Equilateral
This type of triangle is characterized by equal length of sidesEach of its angle measures are 60°Isoceles
This type of triangle has two equal sidesThe angles opposing these sides are also equalScalene
This type of triangle has no equal sidesTherefore, its angles are also not equalThe graph below shows the numbers of orders received by a company for five months.
Answer:
(a) 1950 orders
(b) November to December
Step-by-step explanation:
(a)
The point of the graph lies in the middle of 1900 and 2000, the difference is 100.
So half of 100= (100/2)
=50
Ans- 1900+50=1950
(b)
The question asked you to find when did the numbers of orders have the greatest decrease?
Decrease, in simple terms, is getting low.
So, if you see that the point from the month of NOVEMBER to DECEMBER was the time when the orders decreased the most.
Ans- November to December

Drag each real-world situation to the correct column to show whether it can be modeled by combining additive inverses to get 0. FOR ANYONE WHO WANTS POINTS I JUST WANT TO HELP
Answer:
. An investment account earns 2.8% simple interest.
Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.
B). The price of a stock varies by 2.8% each week.
Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.
Therefore, the answer is NEITHER.
C). An investment account earns 2.8% compound interest, compounded monthly.
Formula to get the value of the final amount in the account is,
Final value = Initial value ×
Here 't' = Duration of investment
It's an EXPONENTIAL FUNCTION.
