1) (1,2) translated two units to the left would be (-1,2)...right? "Translated two units left..." means move horizontally - the negative x direction - 2 units.
"Reflect over the x-axis" means you pretend the point (-1,2) is fastened to the x-axis by a pivoting rod and you just flip it over the horizontal... the x-axis. You'll end-up at (-1,-2)
2) (2,-4). Let's see: over 2 units to the right, down 4 units. Flip it over the x-axis: (2,4)
3) The mid-point will be the point with (x,y,z) values equal to the average of the given 2 x's (7 and -3... the average is 2), the 2 y's (3 and 1 => a y-value of 2) and the average of the 2 z's ( -4 and 0 yield an average of -2) The mid-point is (2,2,-2)
4) Just increase the y-value by 3: You get (2,2)
5) Every coordinate value becomes 3 times the original. (5,-1) becomes (15, -3)
6) (5,2) translated down 4 units is (5,-2. (5,-2) translated translated left 1 unit is (4,-2)
hope this helps

Answer from: Quest

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

Answer from: Quest

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

$ab^2+ac^2=bc^2$

$ab^2+ac^2=x^2$ )

triangle abd and cba are similar,

$\frac{ab}{bc}=\frac{bd}{ab}$

$ab^2=bc\cdot bd$

$25=bc\cdot bd$ (2)

triangle cad and cba are similar,

$\frac{ac}{bc}=\frac{cd}{ac}$

$ac^2=bc\cdot dc$

$7\times 7=bc\cdot dc$

$49=bc\cdot dc$ )

using (1), (2) and (3), we get

$25+49=x^2$

$74=x^2$

hence proved.

therefore option 2 is correct.
