Answer:

C: $x=-3$ or $x=4$

Step-by-step explanation:

To solve the equation $x^2-x-12=0$ we need to factor it

We are looking for two numbers that when multiplied give -12 and when added give -x

This means that when factored, the equation would be $(x-4)(x+3)=0$

Now we can set each of these equal to 0, which means that at

$x=-3$ and $x=4$ , the equation will equal 0

If the numbers -2.5, -1.6, -3 1/10, - 1/10, and -0.5 were graphed on a number line, which would appear farthest to the left?

Leona [35]

Turn the question around.
If all the numbers were positive: 2.5, 1.6, 3 1/10, 1/10, and 0.5, which would be farthest to the right?

The fact is that the negative numbers are a reflection of the positive numbers.
Since 3 1/10 would be farthest to the right with positive numbers, -3 1/10 will be farthest to the left with the negative numbers.
