<span>The answer: b. translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis

If you make the drawing of the situation you realize the you need a reflection through the x-axis, but first you need to translate the polygon several units to the left and upward.

You can see that all the x-coordinates have increased 8 units, so the solution has to include x + 8.

Also, you see that you have to move the polygon 2 units upward before doing the reflection so the solution has to include y + 2.

So, the answer is (x,y) ---> (x + 8, y + 2) and then reflection across the x-axis.

Answer:

THIS IS THE CORRECT ANSWER (also got it right on LSS reflections)

 b. translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis

PLEASE READ THE FOLLOWING. VERY IMPORTANT TO GET PROBLEM RIGHT!!!

THE PENTAGON LOCATION IS AT

A prime B prime C prime D prime E prime on the coordinate plane with ordered pairs at A negative 4, 5, at B negative 6, 4, at C negative 5, 1, at D negative 2, 2, at E negative 2, 4, at A prime 4, negative 7, at B prime 2, negative 6, at C prime 3, negative 3, at D prime 6, negative 4, at E prime 6, negative 6.

SUBSTITUTE THOSE COORDINATES INTO YOUR PROBLEM TO MAKE SURE YOU HAVE THE SAME ONE!!! THERE ARE DIFFERENT VERSIONS OF THIS PROBLEM SO BE CAREFUL!! THIS ANSWER IS ONLY FOR THE COORDINATES SHOWN ABOVE!!!

EDUFIRST ANSWER IS CORRECT!

Here are two number machines, A and B.
Troyanec [42]

Answer:

Step-by-step explanation:

We can write them both like functions like this

Where

x=input

A=Output A

B=Output B

We want the output of A 3 times the output of B this can be written like this:

we replace with the functions

we solve for x

The output that makes the out put of A 3 times teh output of B is

The graphs of f(x) and g(x) are shown below:
Elodia [21]

Answer:

-3.8, 3

Step-by-step explanation:

The solution to a system is where the graph cross each other.  If you look to where they intersect to the left of the origin, where x is negative, it appears that they intersect ALMOST at -4, but not quite.  So -3.8 is going to have to do since we don't have the equations of either graph to find the exact values of x.  To the right of the origin, where x is positive, the graphs cross where x = 3..

The measure of angle 1 is (3x + 10)° and the measure of angle 4 is (4x – 15)°. What is the measure of angle 7
jasenka [17]
Your answer will be 95 degrees. (3x+10)=(4x-15) ends up with x=25. Plug it in to (3x+10). You should get 85 degrees. Using the definition of supplementary angles, angle 3 will be 95. Angle 7 and angle 3 are corresponding angles.
