Answer:
1. x = -4
y = -20
2. x = -1
y = 3
3. x = 7
y = 4
4. x = -6.5
y = -10.5
hope this helps :) sorry if I get it wrong!
Answer:
1) x=−4, y=−20
2) x=−1, y=3
3) x = 7 , y=4
4) x = -6.5 , y = -10.5
Step-by-step explanation:
1) y=5x;−3x+2y=−28
solving system by substitution:
substitute y =5x into 2nd equation:
-3x +2*5x =-28 → -3x+10x = -28 → 7x = -28 → x = -4
plug in x in any equation and solve for y = 5* -4 = -20
2) solving system by elimination:
Multiply the first equation by 7, and the second equation by 5.
7(4x−5y=−19)
5(3x+7y=18)
----------------------
28x−35y=−133
15x+ 35y= 90
Add them up to eliminate y:
43x=−43 divide both sides by 43
x=−1
plug x back into 1st equation to solve for y
4x−5y=−19
(4)(−1)−5y=−19
−5y−4=−19 add 4 to both sides
−5y=−15 divide by -5
y=3
3) y =4 , 5x -6y = 11
plug in 4 for y in 2nd equation and solve for x:
5x -6* 4 =11 simplify
5x - 24 = 11 add 24 on each side
5x = 11 +24 simplify
5x = 35 divide by 5 on each side
x =7
4) y = x -4, 2x - y = -2.5
use substitution method:
2x -(x-4) = -2.5 distribute ( )
2x-x+4 = -2.5 simplify
x + 4 = -2.5 subtract 4 on each side
x = -2.5 -4
x = -6.5
plug in -6.5 for x in 1st equation and solve for y:
y = -6.5 -4
y = -10.5
A box is designed to hold pencils. The front of the box will be made from a clear material for display. The rest of the box will be made from cardboard.
A prism has a length of 20 centimeters, height of 5 centimeters, and width of 4 centimeters.
What is the surface area of the side with the clear material?
Answer:
area of a rectangle/front side of the box = 100 cm²
Step-by-step explanation:
The prism box is a rectangular prism and the front side of the box will be made of the clear material. The other sides will be made of cardboard paper. The surface area of the side with clear material is only the area of the front side of the box. The area of only the front side is the area of 1 rectangle.
The box has a length of 20 cm , height of 5 cm and a width of 4 cm. The surface area of only the front side of the box which is the area of one rectangle only deals with the height and the length.
area of a rectangle/front side = length × height
where
length = 20 cm
height = 5 cm
area of a rectangle/front side = 20 × 5
area of a rectangle/front side = 100 cm²

The Jellybean company is building a new cylinder container with a height of 3.5 inches and a radius of
2 inches. It needs a diagonal divider to separate the two flavors it plans on packing per container. The
production of this divider is being outsourced for manufacturing. What should be the length of the
diagonal divider after removing ¼ of an inch from its top to accommodate for packaging decorative
paper?
Answer:
Length of diagonal paper is 5.15 inch.
Step-by-step explanation:
Please refer to the images attached.
As per the cylindrical image, we have radius given as 2 inches.
Height as 3.5 inches - 0.25 inches = 3.25 inches
If we look closely, we actually have a right angled triangle whose
Base = 2+2 = 4 inches
Height = 3.25 inches
And we have to find the hypotenuse of triangle:
According to pythagoras theorem:
[tex]Hypotenuse^{2} = Base^{2} + Height^{2}[/tex]
[tex]\text{ Diagonal}^{2} = 4^{2} + 3.25^{2}\\\Rightarrow 16 + 10.5625\\\Rightarrow 26.5625\\\Rightarrow \text{Diagonal = }5.15\ inch[/tex]
Hence, Length of diagonal paper required is 5.15 inch.

Which of these pairs of costs and revenues could a company have if it's at its
break-even point?
A. Costs of $3000 and revenues of $5000
B. Costs of $3000 and revenues of $4000
C. Costs of $4000 and revenues of $4000
D. Costs of $4000 and revenues of $5000
Answer: C. Costs of $4000 and revenues of $4000
Step-by-step explanation: took the quiz.
The break-even point for a given company can be Costs of $4000 and revenues of $4000
What is a break-even point?The break-even point is the point at which total cost and total revenue are equal, meaning there is no loss or gain for your small business.
Given are some options we need to find a condition for a company to have a break-even point
Since, the break-even point is a condition of no loss no gain, that the difference of the cost and revenue is zero, that stage is called a break-even point.
From the options, option C is showing a condition of neither gain nor loss, it's having both cost and the revenue same = $4000
Hence, the break-even point for a given company can be Costs of $4000 and revenues of $4000

Answer:
Quadrant 2
Step-by-step explanation:
Sin = opp/hyp and opp is positive in quadrants 1 & 2.
Tan = opp/adj - we need one of these values to be positive and the other negative. adj is negative in quadrants 2 & 3.
Quadrant 2 is found in both of the scenarios that we need to occur.

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).
Answer:
The area of the shaded area is 27 [tex]\pi[/tex]
Step-by-step explanation:
The formula for the area of a circle is :[tex]\pi *radius^2[/tex]
To work this out you would first have to work out the area of the circle. You can do this by multiplying [tex]\pi[/tex] by the radius of 6 squared, this gives you 36[tex]\pi[/tex]. However the question is asking for that section of the circle.
To work out the area of the shaded section you will first have to look at the missing angle, as it is 90° . A circle has 360° and so if we divide 360 by 90, this gives us 4. This tells us that [tex]\frac{3}{4}[/tex] of the circle is shaded as [tex]\frac{1}{4}[/tex] is not.
To work out the area of the shaded area you would divide the area of the whole circle which is 36[tex]\pi[/tex] by 4, this gives us 9[tex]\pi[/tex]. This tells us the area of 1 quadrant of the circle.
The next strep is to multiply 9[tex]\pi[/tex] by 3, this gives us 27[tex]\pi[/tex]. This is because now that we know the area of one quadrant we can find the area of the shaded area which covers 3 quadrant of the circle.
1) Multiply [tex]\pi[/tex] by 6 squared.
[tex]\pi *6^2=36\pi[/tex]
2) Divide 360 by 90.
[tex]360/90=4[/tex]
3) Divide 36 [tex]\pi[/tex] by 4.
[tex]36\pi/4=9\pi[/tex]
4) Multiply 9 [tex]\pi[/tex] by 3.
[tex]9\pi*3=27\pi[/tex]
Answer:
27 pi
