Answers
Given:
The coordinates of triangle ∆ABC are (1,4), (5,6) and (3,10).
The triangle is reflected across y axis forming ∆A'B'C'.
The objective is to find the vertices of the new triangle.
Explanation:
If a triangle with coordinate (a,b) is reflected across y axis, then the change in reflected coordinate will be (-a,b).
If a triangle with coordinate (a,b) is reflected across x axis, then the change in reflected coordinate will be (a,-b).
To find vertices:
Since, the given triangle is reflected across y axis, then the vertices of new triangle will be,
[tex]\begin{gathered} A^{\prime}=(-1,4) \\ B^{\prime}=(-5,6) \\ C^{\prime}=(-3,10) \end{gathered}[/tex]Hence, the vertices of the new triangle are (-1,4), (-5,6) and (-3,10).
4y-3x=-16 I need help with this problem and the problem in the picture please help me this work is already late I need to turn it in
Answers
Answer
x = 1.6
y = -2.8
Explanation
The question wants us to solve the simultaneous equation
4y - 3x = -16
8x - 4y = 24
Adding the two equations, we have,
4y - 3x + 8x - 4y = -16 + 24
5x = 8
Divide both sides by 5
(5x/5) = (8/5)
x = 1.6
If x = 1.6,
8 (1.6) - 4y = 24
12.8 - 4y = 24
-4y = 24 - 12.8
-4y = 11.2
y = -2.8

8. Find the area of the shaded portion of the figure. 10.5cm
Answers
The area = area of the big rectangel - sum of the areas of the two circles
the diameter of each of the circles is 10.5cm
Hence, each circle has a radius of 10.5cm / 2 = 5.25cm
The length of the rectangle = the sum of the diameters of the circles
Therefore
The length of the rectangle = 10.5cm + 10.5cm = 21cm
The width of the rectangle = 10.5cm
Hence,
[tex]\begin{gathered} \text{area of shaded portion = 21}\times10.5\text{ - (}\pi\times5.25^2+\pi\times5.25^2) \\ =220.5-(55.125\pi)\approx47.32 \end{gathered}[/tex]Hence the area of the shaded portion is 47.32 square centimeters

w = l - 16
area = w*l
(l - 16)*l = 80
l^2 - 16l = 80
l^2 - 16l - 80 = 0
(l + 4)(l - 20) = 0

(50k³ + 10k² − 35k – 7) ÷ (5k − 4)How do I simplify this problem
Answers
ANSWER :
[tex]10k^{2}+10k+1-\frac{3}{5k-4}[/tex]
EXPLANATION :
From the problem, we have an expression :
[tex](50k^3+10k^2-35k-7)\div(5k-4)[/tex]The divisor is (5k - 4)
Step 1 :
Divide the 1st term by the first term of the divisor.
[tex]\frac{50k^3}{5k}=10k^2[/tex]The result is 10k^2
Step 2 :
Multiply the result to the divisor :
[tex]10k^2(5k-4)=50k^3-40k^2[/tex]Step 3 :
Subtract the result from the polynomial :
[tex](50k^3+10k^2-35k-7)-(50k^3-40k^2)=50k^2-35k-7[/tex]Now we have the polynomial :
[tex]50k^2-35k-7[/tex]Repeat Step 1 :
[tex]\frac{50k^2}{5k}=10k[/tex]The result is 10k
Repeat Step 2 :
[tex]10k(5k-4)=50k^2-40k[/tex]Repeat Step 3 :
[tex](50k^2-35k-7)-(50k^2-40k)=5k-7[/tex]Now we have the polynomial :
[tex]5k-7[/tex]Repeat Step 1 :
[tex]\frac{5k}{5k}=1[/tex]The result is 1
Repeat Step 2 :
[tex]1(5k-4)=5k-4[/tex]Repeat Step 3 :
[tex](5k-7)-(5k-4)=-3[/tex]Since -3 is a number, this will be the remainder.
Collect the bold results we had from above :
(10k^2 + 10k + 1) remainder -3
Note that the remainder can be expressed as remainder over divisor.
That will be :

What is consecutive integer ?
Integers that follow one another are referred to as consecutive integers. They proceed in a certain order or sequence. For instance, a sequence of natural numbers are all integers. In mathematics, the term "consecutive" refers to an uninterrupted chain of events or a continuous progression, such as when integers follow one another in a sequence where each succeeding number is one more than the one before it. The mean and median are both identical in a collection of successive integers (or in numbers). x + 1 and x + 2 are two consecutive integers if x is an integer.
Here sum of six consecutive integer is -9.
Let us take the 6 consecutive numbers are,
=> x,x+1, x+2, x+3,x+4, x+5
Now sum is -9. Then ,
=> x+x+1+x+2+x+3+x+4+x+5 =-9
=> 6x + 15 = -9
=> 6x = -9-15
=> 6x = -24
=> x = -24/6
=> x= -4
Then 6 integers are ,

Which equation represents a line which is perpendicular to the line y - 6x = -3? Submit Answer Oy= 6x +3 Oy= 1/6x +4 O y= - 1/6x + 8 O y = -6x + 2
Answers
When we have two perpendicular lines their slopes are opposite and inverse.
In this case, we have the equation of the line:
y-6x= -3
Let's solve for y and arrange this equation to make it look like the general form of a linear equation: y=mx+b, where m is the slope of the line.
y-6x= -3
y-6x+6x= -3+6x
y= 6x-3
As we can see, the number that is multiplying the x variable in our equation is 6, the slope of this line is 6.
As mentioned, a perpendicular line to the line y= 6x-3 would have a slope opposite and inverse, then the slope of the line perpendicular to the first line (m2) would be:
[tex]m2=-\frac{1}{6}[/tex]from the options that we have, we can see that the only line that has a slope of -1/6 is the line y= -1/6+8, so that is the right option.

The Solution:
We are required to give an example of a quadratic equation.
Describe a chosen method for solving the quadratic equation.
Solve it using the method you described.
A quadratic equation is an equation in the form:
[tex]ax^2+bx+c=0[/tex]So, an example of a quadratic equation is:
[tex]x^2+x-6=0[/tex]My chosen method of solving the quadratic equation is the Formula Method.
The quadratic formula (also known as Formula Method) is given as
Where
[tex]\begin{gathered} a=\text{ coefficient of x}^2 \\ b=\text{ coefficient of x} \\ c=\text{ constant term} \\ \end{gathered}[/tex]Solving the above quadratic equation using the formula method.
[tex]\begin{gathered} x^2+x-6=0 \\ In\text{ this case} \\ a=1 \\ b=1 \\ c=-6 \end{gathered}[/tex]Substituting these values in the formula, we get
[tex]\begin{gathered} x=\frac{-1\pm\sqrt{1^2-4(1)(-6)}}{2(1)} \\ \\ x=\frac{-1\pm\sqrt{1+24}}{2} \\ \\ x=\frac{-1\pm\sqrt{25}}{2} \\ \\ x=\frac{-1\pm5}{2} \end{gathered}[/tex][tex]\begin{gathered} x=\frac{-1+5}{2}\text{ or }x=\frac{-1-5}{2} \\ \\ x=\frac{4}{2}\text{ or }x=\frac{-6}{2} \\ \\ x=2\text{ or }x=-3 \end{gathered}[/tex]Therefore, the correct answer is x = 2 or -3
(G.11a, 1 point) Points A, C, D, and E are on circle P. 136° 1340 Ε E If arc AD measures 136° and 2 ABD measures 134º, what is the measure of arc CE? o A 152 O B. 67 o C. 116 D. 132
Answers
D. 132º
1) Given that in this circle crossed by two secant lines we can state the following Theorem:
2) then we can write:
[tex]\begin{gathered} m\angle ABD=\frac{AD\text{ +CE}}{2} \\ 134=\frac{136+CE}{2} \\ 134\text{ }\times2=136+CE \\ 268=136+CE \\ CE\text{ =268-136} \\ CE=132 \end{gathered}[/tex]So the measure of the arc CE = 132º (D)
