Answer:
−24
Step-by-step explanation:
Since there is only one negative, this means when all the values are multiplied together the product will be negative. Just multiply all three together to get −24.
(3)(−4)(2)
(−12)(2)
−24
It doesn't matter which order you multiply in in this case.
Either way you still have the exact same amount of material length no matter if melted and remolded or simply cut
Answer:
Start at -4 and go up to -1.
Step-by-step explanation:
Answer:
quadratic
Step-by-step explanation:
The x-values are sequential, so we can look at the y-values.
Differences from one to the next are ...
-7, -1, 5, 11, 17
And the differences of these numbers are ...
6, 6, 6, 6
When <em>second</em> differences are constant, the sequence can be produced by a <em>second</em>-degree (quadratic) polynomial.
__
Here, that polynomial is ...
y = 3x² +2x -1
The regression functions of a graphing calculator can help you find the appropriate formula.
A graph of the equation shows the appropriate choice to be
C. 2_____
If you would rather, you can look at the value of the discriminant. For the equation y = ax²+bx+c, the discriminant (d) is
d = b²-4ac
For your equation, this evaluates to
d = (-8)²-4(2)(5) = 64 -40 =
24When the discriminant is
positive, the function has
two real roots (2 x-intercepts). When it is zero, there is only one x-intercept, and when it is negative, there are none (the roots are complex).
