By inspection , which system would have no solution

For a linear system like you could say that by inspection there is no solution because "two (of the same) numbers can't have different sums." you could say that by inspection, the solution is (0, 5) because both lines have the same y-intercept but different slopes.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
