Which describes the transformation that could have been applied to triangle ABC?
A dilation could have been applied because all of the
vertices decreased by 2 units.
O An isometric transformation could have been applied
because all of the vertices moved 2 units right and 2
units down.
A dilation could have been applied because all of the
vertices increased 2 units.
An isometric transformation could have been applied
because all of the vertices moved 2 units left and 2
units up.
Answer: I’m sorry im late, but the answer to your question should be B.
Step-by-step explanation: reason being is because the figure didnt grow/shrink like it would for a dilation so that gets rid of A. And C. And its not D. Because the dashed triangle is our original triangle not our new one so it would not make sense for it to go up and to the left. Thanks for coming to my ted talk
The image A'B'C' is formed by an isometric transformation because all of the vertices moved 2 units right and 2 units down, the correct option is B.
What is Transformation?Transformation is the process of changing the graph to a new graph by Rotation, Reflection, Translation, and Dilation.
Rotation is a type of transformation of an object on an x-y plane, when an object is turned clockwise or anticlockwise by a certain angle, the object is said to be rotated.
Reflection is creating a mirror image of the object, which is same in shape and size but only the coordinates have been changed.
Translation is moving the object, up, down, left or right on the coordinate axis.
Dilation is changing the size of the object, the original object is either enlarged or compressd by certain scale factor.
The object ABC shown in the image has coordinates A ( -2, 5), B (-5, -3), C(1, -3) and,
The image has the cooridnates A'(0,3), B'(-5,-3) , C'(3, -5).
The coordinates have been transformed by translation.
The transformation is an isometric transformation could have been applied because all of the vertices moved 2 units right and 2 units down.

What is the y=Mx+b of this equation
Answer:
[tex]y = - 6x - 8[/tex]
Step-by-step explanation:
The y-intercept is where the line itersects the y-axis, which is the dark vertical line. This is -8 represented as the constant in the equation.
To find the slope, find the rise over run. Every time the line goes over 1 it goes down 6, so the slope would be -6.

Use the quadratic formula to find the solutions to the equation.
3x2 - 10x + 5 = 0
Answer: A
Step-by-step explanation:
3x² - 10x + 5 = 0
a = 3 b = -10 c = 5
Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions
=> x = [tex]\frac{10+\sqrt{40} }{6}[/tex] or x = [tex]\frac{10-\sqrt{40} }{6}[/tex]
[tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.
What is quadratic equation?
Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = [tex]ax^{2} +bx+c[/tex] = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
Given quadratic equation
[tex]3x^{2} -10x+5=0[/tex]
a = 3, b = -10, c = 5
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]x= \frac{-(-10)\pm \sqrt{(-10)^{2} -4(3)(5)} }{2\times3}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{100 -60} }{6}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex]
Hence, [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.

Jenny calculates that this is a percentage increase of 19%
Is Jenny's percentage correct?
PLZ SHOW WORKING OUT
Answer:
Jenny's percentage isn't correct
Step-by-step explanation:
You'd have to divide first:
38 / 32 = 1.1875 = (rounded) 1.19%
The percentage increase is 1.19%
Answer:
the percentage is 100 because you add 32 and 38 and equals 100 if you were to subtract you would have got 6%
what is the sell tax of 8.00 dollars
Answer:
A tax of 7.5 percent was added to the product to make it equal to 8.6. So, divide 7.5 by 100 to get 0.075. Divide the final amount by the value above to find the original amount before the tax was added. In this example: 8.6 / 1.075 = 8.

Evelyn is buying a motorcycle that costs $14,000. The tax rate is 6.75%, and she plans to make a down payment of $1,500. The sales tax is
added before the down payment is applied. She is considering a three-year loan
Answer:
449.10
Step-by-step explanation:
Her monthly payment, if she is considering a three-year loan is $373.47
Given the cost of the motorcycle to be $14000
If the tax rate is 6.75%, the total cost plus tax is expressed as:
Final cost = 14000+(0.0675 * 14000)
Cost of motorcycle = 14000 + 945
Cost of motorcycle = $14945
If she plans to make a down payment of $1,500 before the sales tax is applied, then;
Balance = 14945 - 1500
Balance = $13,445
If she considers a three-year loan, her monthly payment will be ;
Monthly payment = 13,445/36
Monthly payment = $373.47
Hence her monthly payment if she is considering a three-year loan is $373.47

Which angle in ABC has the largest measure?
Answer:
Angle B
Step-by-step explanation:
Angle B because the measure of angle B is 12 . Angle A has a measure of 7 and angle C has a meausre of 10 which both measures of the angles are less than angle B. Think of it like this... 17 people (7+10) went to a Bakery. There were only 7 cupcakes and 10 sweet potato pies. To start with there were 35 cupcakes and 35 sweet potato pies. 7 people ordered cupcakes and 10 people ordered sweet potato pie. There were 18 left of the 2 deserts. 18 is greater than 7 and 10. That´s why angle B is the angle that has the largest measure. 12 is greater than 7 and 10. If there were only 7 milkshakes left and 10 people wanted a milkshake, only 7 people would be able to get a milkshake. 3 people wouldn´t be able to get a milkshake
So angle B is the correct answer.

Sustitute n = 4
= 28 - 12 √(4 ÷ 2)
= 28 - 12√2
= 28 - 12 x 1.414
