Answer:
A) reflection across the y-axis
Step-by-step explanation:
If 
, then this says that two 
-coordinates are equal for opposite values of 
.
Let 
a point on 
.
Then 
.
We also know that 
and therefore 
is also a point on the graph.
If you graph [/tex](-a,b)[/tex] and you will see they are symmetrical to each about the -axis.
Example if given both and 
, then 
. This means both (2,3) and (-2,3) are points on the graph.
Here is what those two points look like on a Cartesian Plane (please see graph in picture).
Answer:
The number of commercials is 340 and the number of movies are 334.
Step-by-step explanation:
Let the number of commercials be = C
number of movies be = M
According to given conditions:
C = 6 + M --------- eq1
C + M + 6 = $680 ------ eq2
Putting eq1 in eq2:
6 + M + 6 + M = $680
12 + 2M = $680
Subtracting 12 from both sides:
2M = $680 - 12
2M = 668
Dividing both sides by 2:
M = 668/2
M = 334
For finding number of movies put value of M in eq 1
C = 334 + 6
C = 340
So The number of commercials is 340 and the number of movies are 334.

Answer:
-4 < x < -8
Step-by-step explanation:
Given solve -x > 8 or -x < 4.
Solve each inequality first
-x > 8
Divide both sides by -1
-x/-1 > 8/-1
x < -8
Also if -x < 4
Divide both sides by -1
-x/-1 < 4/-1
x > -4
Combine both inequality x < -8 and x > -4
-4 < x < -8
<em>Hence the solution set is -4 < x < -8</em>
Y = -9x is proportional because its in the format y = kx
if you graph this equation youll see that it is a straight line that passes through the origin

Answer:
There isnt any solution.
Step-by-step explanation:
but these are the steps:
Step 1: Simplify both sides of the equation.
5x−3+2x=x+7+6x
5x+−3+2x=x+7+6x
(5x+2x)+(−3)=(x+6x)+(7)
7x+−3=7x+7
7x−3=7x+7
Step 2: Subtract 7x from both sides.
7x−3−7x=7x+7−7x
−3=7
Step 3: Add 3 to both sides.
−3+3=7+3
0=10
