The answer to your question is 5
When dividing two fractions, invert the second one and multiply the 2 top numbers and the 2 bottom numbers.
3/4 / 1/4 = 3/4 * 4/1 = 12/4 = 3
16x-7≤-71
Add 7 to both sides
16x≤-64
Divide both sides by 16
x≤ -4
Hope this helps! :)
Part A:
We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.
Part B:
As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
