No because 3x+2y=2 is not a solution. When you plug in the number it would equal to 15
Find the total length in inches of one of the rolls:
15*12=180 inches.
Now multiply the length of one roll (180 inches) by 2 to find the total length:
180*2=360 inches.
Divide by the width of the strips to find the total number of strips:
360/9=40 strips
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.
