Answer:
A.
Step-by-step explanation:
The lines touch along every point so they are on top of each other.
The given system of equations represent two coinciding lines.
What is a system of linear equations?A system of linear equations is a group of equations having same number of variables and degree.
For the n number of variables n number of equations are required.
On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.
A linear equation in two variables represent a straight line.
As system of equations in two variables can be represented as
a₁x + b₊y + c₁ = 0
a₂x + b₂y + c₂ = 0
When there are two such equations having infinite solutions the relation between the coefficients is given as,
a₁/a₂ = b₁/b₂ = c₁/c₂
It implies that there are infinite points common between them which is possible only when these two lines are coinciding.
Hence, the graph of corresponding two lines in the x- y plane represents coinciding lines.

Jack bought a motorbike the original price was $1800 but he got a discount of 15% what was the discounted price of the bike
Answer:
$1530
Step-by-step explanation:
Hi there!
What we know
Original price was $1800There was a discount of 15%If this motorbike was on sale for 15% off, then we know that its discounted price is 85% of the original price (100-15=85)
Then, to find the discounted price, we multiply 1800 by 85%:
1800 × 85%
Change 85% into a decimal
= 1800 × 0.85
= 1530
Therefore the discounted price of the motorbike was $1530.
I hope this helps!

Which of the equations below represents a line parallel to the yaxis?
A. X= -y
B. X= 4y
C.x=y
D.X= 4
HELP
Answer:
x=4
Step-by-step explanation:
The y axis is a line where the value of x does not change ( x=0)
It is a vertical line

I need help with finding the volume of this rectangle and also what formula you used so I can understand it. Thanks
Answer:
Step-by-step explanation:
Equation
The volume formula is
V = L * W * H
Givens
From the diagram
L = 6 mi
W = 2 mi
H = 5 mi
Solution
V = 6 * 5 * 2
V = 60 cubic miles

Answer:
150.8[tex]yd^3[/tex]
Step-by-step explanation:
I helped lol.
Have a nice day! :-)
Answer:
150.7
Step-by-step explanation:
Formula for volume of a cone = [tex]\pi r^2\frac{h}{3}[/tex]
where r = radius and h = height
We are given the diameter ( 8yds ) and the height ( 9yds )
In order to find the volume we need to find the radius
We can do this my dividing the diameter by 2 ( this is because the radius is equal to half the length of the diameter)
8/2 =4
So the radius is equal to 4yds
Now we plug in the values into the formula
( remember it says use 3.14 for π )
[tex]V=(3.14)4^2\frac{9}{3} \\4^2=16\\16*3.14=50.24\\\frac{9}{3} =3\\3*50.24=150.72[/tex]
Finally we round to the nearest tenth and get that the answer is 150.7yd²

Here is a triangular prism. 4 cm 10 cm 5cm 5cm 6cm
A. What is the volume of the prism, in cubic centimeters?
B. What is the surface area of the prism, in square centimeters?
Answer:
(A) 120 cm³
(B) 184 cm²
Step-by-step explanation:
(A)
Assuming the diagram attached is thesame as the one needed to complete the question,
Applying
V = A'×L................... Equation 1
Where V = volume of the prism, A' = Area of the triangular base, L = Length of the prism.
But,
A' = 1/2bh............. Equation 2
Where b = base of the triangle, h = height of the triangle.
Substitute equation 2 into equation 1
V = 1/2bh(L)............... Equation 3
From the question,
Given: b = 6 cm, h = 4 cm, L = 10 cm
Substitute these values into equation 3
V = 1/2(6×4×10)
V = 120 cm³
(B)
Surface area of the prism(A) = bh+L(a+b+c).............. Equation 4
Given: b = 6 cm, b = 5 cm, c = 5 cm, L = 10 cm, h = 4 cm
Substitute these values into equation 4
A = (6×4)+10(5+5+6)
A = 24+160
A = 184 cm²
What is the equation of the line perpendicular to y = -x+6 that passes through the
2
point (4, 1)?
Answer:
[tex]y=x-3[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Perpendicular lines always have slopes that are negative reciprocals (ex. 3 and -1/3, 1/2 and -2, etc.)1) Determine the slope (m)
[tex]y = -x+6[/tex]
Looking at the given line, we can identify clearly that -1 is in the place of m, making it the slope of the line. Because perpendicular lines have slopes that are negative reciprocals of each other, we know that the slope of the line we're solving for is 1. Plug this into [tex]y=mx+b[/tex]:
[tex]y=x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=x+b[/tex]
Plug in the given point (4,1)
[tex]1=4+b[/tex]
Subtract 4 from both sides
[tex]1-4=4+b-4\\-3=b[/tex]
Therefore, the y-intercept is -3. Plug this back into [tex]y=x+b[/tex]:
[tex]y=x-3[/tex]

Note: Consider we need to find the factor form of the given expression by taking out the GCF.
Given:
The expression is:
[tex]-42k^3+24k^4+12k^5[/tex]
To find:
The factor form of the given expression.
Solution:
We have,
[tex]-42k^3+24k^4+12k^5[/tex]
It can be written as:
[tex]=6k^3(-7)+6k^3(4k)+6k^3(2k^2)[/tex]
Taking out the greatest common factor (GCF), we get
[tex]=6k^3(-7+4k+2k^2)[/tex]
Therefore, the factor form of the given expression is [tex]6k^3(-7+4k+2k^2)[/tex].
