Student005,
In order to find the answer you need to convert each notation into standard form then order them into least to greatest.
Therefore your answer is option A "1.94 × 10^-5, 1.25 × 10^-2, 6 × 10^4, and 8.1 × 10^4."
Hope this helps!
The <em><u>correct answer</u></em> is:
A 180° rotation followed by a translation 1 unit down.
Explanation:
The points are mapped as follows:
J(3, 4)→J'(-3, -5)
K(3, 1)→K'(-3, -2)
L(1, 1)→L'(-1, -2)
A 180° rotation maps a point (x, y) to (-x, -y). This would map
J(3, 4)→(-3, -4)
K(3, 1)→(-3, -1)
L(1, 1)→(-1, -1)
The difference between these points and the image points are that each y-coordinate of the image is 1 lower than these. This means a translation 1 unit down would result in the image points.
3(-3-3x)+4=-5
One solution was found :
x = 0
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*(-3-3*x)+4-(-5)=0
Step by step solution :
Pull out like factors :
-3 - 3x = -3 • (x + 1)
Equation at the end of step 2 :
(-9 • (x + 1) + 4) - -5 = 0
Equation at the end of step 3 :
-9x = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : -9x = 0
Multiply both sides of the equation by (-1) : 9x = 0
Divide both sides of the equation by 9:
x = 0
One solution was found :
x = 0
