Answer:

(1) (B) y = x and

(2) (D) 10 units to the right and 4 units up.

Step-by-step explanation:

Since we are given that ΔA'B'C' is formed after a sequence of transformations applied to ΔABC.

The first is a reflection across a line and second is a translation.

The co-ordinates of point C are (-4, -2). After reflection from the line y = x, the co-ordinates becomes (2, -4).

Also, the coordinates of point C' are (12, 0).

So, to reach point C' from point C, we should add 10 units to the x-coordinate and 4 units to the y-coordinate.

That is, the translation of 10 units right and 4 units up.

Thus, the complete transformation is

The sequence of transformations that maps ∆ABC to ∆A′B′C′ is a reflection across the line y = x followed by a translation 10 units right and 4 units up.

Thus, the correct answer is (1) y = x and (2) 10 units to the right and 4 units up.

What is the difference written in scientific notation? 0.00067 - 2.3 x 10^5

shepuryov [24]

0.00067=67X10^5 so

67X10^5-2.3X10^5

64.7X10^5 which can be expressed as:

6.47X10^6

(not sure if it matters to you or not, but technically we only had two significant figures so it should be rounded to 6.5X10^6)

Given that YX=YZ write an inequality that relates m

Westkost [7]

Answer:

C. m<XYA > m<ZYA.

Step-by-step explanation:

Since XY = YZ, as indicated in the information given, the angles opposite XY and YZ would also be of equal measure of degrees.

Thus, XA = 5. The angle opposite XA is m<XYA.

ZA = 3. The angle opposite ZA is m<ZYA.

Since XA > ZA, therefore,

m<XYA > m<ZYA.

Write an equation of the form y = mx for the line shown below.<br> (-1,-2)<br> Answer here

Debora [2.8K]

Answer:

$y=2x$

Step-by-step explanation:

<u>Equation of a Line</u>

Two variables x and y are linearly dependent when they are related by the equation

$y=mx+b$

where m is the slope and b is the y-intercept, or the value of y when x equals 0. We are given a particular equation for the line such as b=0, so we only need one point to compute m. That point is (-1,-2):

$-2=m(-1)$

It follows that

$m=2$

Thus the equation of the line is

$\boxed{y=2x}$

Dr. Nefario put $5000 in the bank and left it there for 6 months. What simple interest rate would he need to have in order to ha

Sonja [21]

Answer: The interest rate is .166%

Step-by-step explanation:

So what I did was divide $50(Amount at the end) by 6 (the number of months). Which would give me the amount of money he made per month ($8.333...). So then $8.333.../$5000(Total $) is .166...% (Interest rate)
