Find the coordinates of C' after a reflection across the line
iragen [17]
<h3>Answer:  (4,2)</h3>

==============================================================

Explanation:

C is at (0,0). Ignore the other points.

Reflecting over y = 1 lands the point on (0,2) because we move 1 unit up to arrive at the line of reflection, and then we keep going one more unit (same direction) to complete the full reflection transformation. I'll call this point P.

Then we reflect point P over the line x = 2 to arrive at the location Q = (4,2). Note how we moved 2 units to the right to get to the line of reflection, and then keep moving the same direction 2 more units, then we have applied the operation of "reflect over the line x = 2"

So we have started at C = (0,0), moved to P = (0,2) and then finally arrived at the destination Q = (4,2). This is the location of C' as well.

All of this is shown in the diagram below.

Five times a number decreased by 18 minus 4 times the same number is -36. what is the number?
kaheart [24]

(5x - 18) - 4x = -36

Let's solve your equation step-by-step.

5x − 18 − 4x = −36

Step 1: Simplify both sides of the equation.

5x − 18 − 4x = −36

5x + −18 + −4x = −36

(5x + −4x) + (−18) = −36 (Combine Like Terms):

x + −18 = −36

x − 18 = −36

Step 2: Add 18 to both sides.

x − 18 + 18 = −36 + 18

x = −18


Answer: ========> x = -18 is the number




Hope that helps!!!! : )
