The graph below shows the solution to which system of inequalities?

1 answer:

7 0

Answer: C
Explanation: Let's find each equation without any inequalities first. We have a dotted line at y = 1, so we can already remove A and B. Now, a dotted line represents exclusivity and hence; it should not include the = sign.

Thus, by elimination, the answer must be C.

Which shows the correct substitution of the values ab and c from the equation 0 = - 3x ^ 2 - 2x + 6 into the quadrati formula?

scZoUnD [109]

The answer would look something like this:

$\frac{2+-\sqrt{2^{2}-4(-3)(6) }}{2(-3)}$

There could also have a simplified version.

I hope this helps.

Miguel is going for a walk. he takes 3 hours to walk 7.5 miles. what is his speed?

daser333 [38]

We have a ratio of 3 hours / 7.5 miles
We want to know how many miles he can walk in 1 hour so, divide both sides by 3 -> 1 hour / 2.5 miles
He is walking at 2.5 mph
