Answer:
false
Step-by-step explanation:
This is false because if you look at a grid the x lays right by the 0.
Answer:
We have the system:
x ≤ 7
x ≥ a
Now we want to find the possible values of a such that the system has, at least, one solution.
First, we should look at the value of a where the system has only one solution:
We can write the 2 sets as:
a ≤ x
x ≥ 7
So, writing both together:
a ≤ x ≤ 7
if a is larger than 7, we do not have solutions.
then a = 7 gives:
7 ≤ x ≤ 7
Here the only solution is 7.
Now, if a is smaller than 7, for example 5, we have:
5 ≤ x ≤ 7
Now x can take different values, so we have a lot of solutions.
Then the restrictions for a, such that the system has at least one solution, is:
a ≤ 7.
Answer:
3/2
Step-by-step explanation:
Finding the perpendicular line to a given line is easy. Find the slope (m) in the equation (directly left to the variable, x). Flip the fraction (or set it over 1 if a whole number), and change the sign to the opposite.
In this case, the perpendicular line's slope will be 3/2.
