Answer:
An unknown variable by reversing the process used to form the original equation.
Step-by-step explanation:
The opposite process rule says to solve for - an unknown variable by reversing the process used to form the original equation.
If an equation indicates an operation such as addition, subtraction, multiplication, or division, solve for the unknown variable by using the opposite process.
For example:
Lets say we have to find 
Here 25 is subtracted from both sides of the equation to isolate x.
we get x = 10

Answer:
243
Step-by-step explanation:
STEP 1: Evaluate the variables
9(2 + (5)(5))
STEP 2: Then from there you can multiply the equation
18 + 225 = 243
Answer:
y = 2/3x + 19/3
Step-by-step explanation:
First, this is your current equation: y = 2/3x + b. Plug in your point to the equation, it should look like this: 5 = 2/3(-2) + b. 2/3 times -2 equals -4/3. So, this is what your equation should look like: 5 = -4/3 + b. Add 4/3 to both sides of the equation to get 19/3 = b. Go back to your original equation and plug 19/3 to b. This is your final equation: y = 2/3x + 19/3. Hope this helped!
Answer:
1. Construct a segment XY on the a sketch.
2. Elsewhere on the sketch, draw a line and create a point on the line . Label the point P.
3. Select point P and line segment XY. Construct circle by center and radius.
4. Select the circle and line, then construct point of intersection. Label one of the points of intersection point Q.
5. Select point P and point Q. Construct segment PQ.
6. Select the circle, line, and other point of intersection. Hide objects. Only segment XY and segment PQ should be visible on the sketch.
7. Try dragging point X. Segment PQ should lengthen and shorten as segment XY does.
No, it won’t work. The greatest common factor between 45 and 27 is 9, but 45-27=18. So it cannot work.
