Answer:

Answer: Third option is the right answer.

Step-by-step explanation:

First we the write the expression

(a+b)(a^{2}+b^{2}-ab)

Now teacher says that the product of these polynomials will result in the sum of  a^{3}+b^{3}

Now the teacher ask if we put the value of a = 2x and b = 1 then what will be the expression look like.

(2x+1)\left [ (2x)^{2}+(1^{2})-(2x)(1)\right ]

=(2x+1)(4x^{2}+1-2x)

So third option is looking like our expression.

The question is in the picture. Plz helppp it is due tonight

Answer:

Step-by-step explanation:

We're given one equation, we have to find the other equation and solve each for 200, and whichever has the lower x is the winner

for Jayden we are given

(0, 48), (1, 56), (2, 64), (3, 72), (4, 80)

This looks to be a line. The y values are each separated by a common difference

We can use two points to describe the line

m = \frac{y_2-y_1}{x_2-x_1} = \frac{80-48}{4-0} = \frac{32}{4} = 8\\  K = 8m + b\\48 = 8(0) + b\\b = 48\\so\\K = 8m + 48

Now we can set both K = 8m + 48 and K = m^2 + 10 equal to 200

200 = 8m + 48\\152 = 8m \\m = \frac{152}{8} = 19

200 = m^2 + 10\\m^2 = 190\\m = \sqrt{190} = 13.784

The transformation from 1 to 2 is a translation, as the shape is moved from one point to another with no rotation, reflection, or change in size.

The transformation from 2 to 3 is a reflection, as the shape is now upside down. It is still the same distance from the y-axis.

The answer is D. translation, then reflection.
