Step-by-step explanation:
Percentage discount on the cost of the sofa = 20%
What is percentage discount?Percentage discount = (Absolute discount / Cost price) × 100
Given,
Cost price = $600
Absolute discount = Cost price - Selling price
Absolute discount = $600 - $480
= $120
Percentage discount = (Absolute discount / Cost price) × 100
= (120/600) × 100
= 120/6
= 20%

Dilation from the origin by scale factor r=1/2 maps quadrilateral ABCD to quadrilateral ABCD not shown
Answer:
C'(4, 4)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Dilation is the enlargement or reduction in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new point would be at A'(kx, ky).
Given that quadrilateral ABCD is dilated by a scale factor of 1/2 to form quadrilateral A'B'C'D'.
The vertices of quadrilateral ABCD is given by A(2, 2), B(4, 8), C(8, 8) and D(6, 4).
If quadrilateral ABCD is dilated by 1/2 to form quadrilateral A'B'C'D, the vertices of quadrilateral A'B'C'D would be A'(1, 1), B'(2, 4), C'(4, 4) and D'(3, 2).

The sum of 5 consecutive even numbers is 100 ples help :/
Consecutive even numbers are numbers that go in order, such as 1,2,3,4,5.
There are 5 even numbers.
They would be x, x+2, x+4, x+6, and x+8 (you add 2 each time so they are even).
Now when adding all these numbers, you get 100.
So there's your equation.
x+x+2+x+4+x+6+x+8=100
Add like terms.
5x+20=100
Solve for x.
5x=80
x=16
So the first number is 16.
The second is 18.
Third is 20.
Fourth, 22.
And fifth, 24.
You can add them to see if you are correct.
16+18+20+22+24=100
The numbers are 16,18,20,22, and 24.

I need the answer for the Linear equation of the below graph
Answer:
y = - [tex]\frac{3}{4}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = [tex]\frac{0-3}{4-0}[/tex] = - [tex]\frac{3}{4}[/tex]
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - [tex]\frac{3}{4}[/tex] x + 3 ← equation of line

Solve the equation 1.5x + 18 =3
Answer:
x=10
Step-by-step explanation:
Simplifying
1.5x + 3 = 18
Reorder the terms:
3 + 1.5x = 18
Solving
3 + 1.5x = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 1.5x = 18 + -3
Combine like terms: 3 + -3 = 0
0 + 1.5x = 18 + -3
1.5x = 18 + -3
Combine like terms: 18 + -3 = 15
1.5x = 15
Divide each side by '1.5'.
x = 10
Simplifying
x = 10

The area of the trapezium for the given figure is 35 cm².
What is trapezium?A trapezium is a quadrilateral with four sides where two sides are parallel to each other.
We have,
The area of the trapezium.
= 1/2 x (sum of the parallel sides) x height
Now,
Parallel sides = 6cm and 8cm
Height = 5 cm
Now,
Area.
= 1/2 x (6 + 8) x 5
= 1/2 x 14 x 5
= 35 cm²
Thus,
The area of the trapezium is 35 cm².

The coordinates of M is M’(4,-3).
What is rotation?Rotation means the circular movement of an object around a center. It is possible to rotate different shapes by an angle around the center point.
Given:
LMNP is rotated 90° clockwise around the origin.
If we rotate the figure in LMNP about 90 degrees then the coordinates will change into
(x, y) to (y, -x).
As, x= 3, y=4
Hence, the coordinates of M is M’(4,-3).

Answer:
f(-9) = -189
Step-by-step explanation:
f(x) = -3x² - 6x
Plug in -9 for x.
f(-9) = -3(-9)² - 6(-9)
According to PEMDAS (parentheses/exponents | multiplication/division | addition/ subtraction), we should solve the exponents first.
f(-9) = -3(81) - 6(-9)
Now, multiply.
f(-9) = -243 + 54
Now, add.
f(-9) = -189
