Answer:
y = 5x² -30x +39
Step-by-step explanation:
Multiply it out and collect terms.
y = 5(x -3)² -6
y = 5(x² -6x +9) -6 . . . . . expand the square
y = 5x² -30x +45 -6 . . . . use the distributive property
y = 5x² -30x +39 . . . . . . collect terms
_____
The expansion of a binomial square is ...
(a +b)² = a² + 2ab + b²
In this problem, we have a=x, b=-3.
Answer:
y = 5x² -30x +39

It states reflected over the y-axis, so treat the y axis as a mirror and you will realise that the x is always the inverse number. For example, if it is -2, the reflected value will be 2. (y remains unchanged)
X: (10,2)
Y: (8,-7)
Z: (-9,5)

Step-by-step explanation:
The system of equations is graphed on the coordinate plane.
y=-5/3x+3
y=1/3x - 3
Enter the coordinates of the solution to the system of equations
in the boxes.
Answer: The solution is (3, -2)
This means that x = 3 and y = -2 pair up together.
=====================================================
Explanation:
The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).
-----------------
As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation
y = (-5/3)x + 3
y = (-5/3)*3 + 3
y = -5+3
y = -2
The first equation is confirmed. Let's check the second equation
y = (1/3)x - 3
y = (1/3)*3 - 3
y = 1 - 3
y = -2
Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.

how can i solve this
tan2x/(tan4x-tan2x)
Answer: = cos 4x
[tex]\frac{tan2x}{tan4x-tan2x}\\\\=\frac{tan2x}{\frac{2tan2x}{1-tan^{2}2x }-tan2x }\\\\=\frac{tan2x(1-tan^{2}2x) }{2tan2x-tan2x(1-tan^{2}2x) }\\\\=\frac{tan2x(1-tan^{2}2x) }{tan2x(2-1+tan^{2}2x) }\\\\=\frac{1-tan^{2}2x }{1+tan^{2}2x } \\\\=\frac{1-\frac{sin^{2}2x }{cos^{2}2x } }{1+\frac{sin^{2}2x }{cos^{2}2x } }\\\\=\frac{cos^{2}2x-sin^{2}2x }{cos^{2}2x+sin^{2}2x } \\\\=\frac{cos4x}{1}\\\\=cos4x[/tex]

Another house is sold for £283,392
This is 1.6% less than the price paid for the house. What was the price paid?
Answer:
the price paid is £288,000
Step-by-step explanation:
The computation of the price paid is shown below:
Sale of the another house is £283,392
Since the another house would be 1.6% less than the price paid
So, the price paid would be
= £283,392 × 100 ÷ (100 - 1.6%)
= £283,392 × 100 ÷ 98.4
= £288,000
Hence, the price paid is £288,000
Chris borrows £6000 at a simple interest rate of 10% per year.
He pays the money back after 4 years.
How much does he pay back in total?
9514 1404 393
Answer:
£8400
Step-by-step explanation:
The amount due after t years is ...
A = P(1 +rt)
A = £6000(1 + 0.10·4) = £6000·1.40
A = £8400
Chris pays back £8400 in total.

Answer:
There's no solution to this equation, when 2 equations have the same slope but different y-intercepts, they're parallel. This means they never intercept and there is NO solution and we can't solve for x.

Brandon Brandon Drew the two congruent squares shown he divided one square into 2 congruent triangular parts he divided the other square into 2 congruent rectangular parts
Incomplete question: Options
(a) Each triangular part and each rectangular part represents 1/2 the area of one square.
(b) Each triangular part has an area that is greater than the area of each rectangular part.
(c) Each triangular part and each rectangular part represents 1/4 the area of one square
(d) Each rectangular part has an area that is greater than the area of each triangular part.
See attachment for squares
Answer:
(a) Each triangular part and each rectangular part represents 1/2 the area of one square.
Step-by-step explanation:
Given
See attachment
Required
Which statement is true
Before the division, the area of both squares is:
[tex]Area = l * w[/tex]
After the division:
The area of the triangle is:
[tex]Area = \frac{1}{2} * base * height[/tex]
[tex]A_1 = \frac{1}{2} * l * w[/tex]
Substitute Area for l * w
[tex]A_1 = \frac{1}{2} *Area[/tex]
This equals half the area of the square
The area of the rectangle is:
[tex]Area = length * width[/tex]
The length of the rectangle is now half the length of the original square.
So, we have:
[tex]A_2 = \frac{1}{2} l * w[/tex]
Substitute Area for l * w
[tex]A_2 = \frac{1}{2} *Area[/tex]
From the values of A1 and A2, we can conclude that (a) is true
Recall that the center of dilation is point J. On the logo, identify one or two line segments: that contain the center of dilation that do not contain the center of dilation that lie on a line that passes through the center of dilation Record the names of the line segments you identified and the category they belong to. What differences do you notice in the way these categories of line segments are mapped from the preimage to the image?
PLATO
Answer:
HA , LJ , and IK contain the center of dilation. Line segments that contain the center of dilation in the preimage also contain the center of dilation in the image. GF , HI , and KL do not contain the center of dilation. Line segments that do not contain the center of dilation in the pre image are mapped onto distinct lines parallel to the original, corresponding line segment. HL does not contain the center of dilation either but it does lie on a line that passes through the center of dilation. Line segments that lie on lines passing through the center of dilation in the preimage lie on the same lines in the image.
