So we are trying to solve for x so in order to do that we need to get x by itself on one side of the equal sign
first we are going to combine like terms on each side of the equal side
so on the left side we see 4+9 these are booth whole numbers not attached to a variable so we can simplify this by adding these two values together making our equation: x/13 = 12
our x is still not by itself so in order to get it by itself we need to get rid of that 13
we need that x is being divided by 13 so in order to get rid a divided value we have to do the opposite to both sides - multiply by 13 on each side!
x/13 x 13 = x
12 x 13 = 156
so our equation is now:
x = 156
is our x by itself on one side of the equal sign? yes! so our x value is 156
Answer:
B) -1 and D) 1
Step-by-step explanation:
We want to find the solution to
Which means that we want to find the values of x at which the two functions f(x) and g(x) are equal.
In order to do that, we have to look at the table, and see at which values of x the two functions have the same value.
We observe that the only two values at which this occurs are:
at 
, where both functions are equal to 
at 
, where both functions are equal to 
Answer:
A line segment has one dimensions.
Step-by-step explanation:
A line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints.
Dimension is an aspect or feature of an object.
A line segment, let us say AB has two endpoints and has only one measurable feature that is its length which is actually the distance between the two end points A and B.
Hence, a line segment is one-dimensional.
