Answer:
The last choice is the one you want
Step-by-step explanation:
First of all, a parabola has a minimum value if it is a positive parabola, one that opens upward. The first and the third parabolas are negative so they open upside down. That leaves us with choices 2 and 4. We find the side to side and up or down movement by finishing the completion of the square that has already been started for us. Do this by factoring what's inside the parenthesis into a perfect square binomial.
The second one factored becomes:
which reflects a shift to the right 3 and up 1. Not what we are asked to find.
The fourth one factored becomes:
which reflects a shift to the right 3 and down 5. That's what we want!
Answer:
It tell the direction and the steepness of the line. Which means how much they rise or how much they fall, horizontal or vertical. It represent by the letter m
Step-by-step explanation:
m= y/x
more detail
m= y₂ - y₁ / x₂ - x₁
Answer:
<em>See below</em>
Step-by-step explanation:
In this example we are to consider the equation 2x - 5 = 4x + 12, and are asked to solve for x. Well let us take the first approach, a mathematical one;
Now consider the explanation, " talking over a phone to a friend. "
First you would subtract 2x on either side of the equation, canceling the 2x on one side, and subtracting 2x from 4x on the other, resulting in the simplified equation - 5 = 2x + 12. Subtracting 12 from either side we cancel the 12 on one side, and subtract - 12 and - 5 on the other. We now get - 17 = 2x. Dividing 2 on either side, x = - 8.5!
