Answer:
True answer: -24
Step-by-step explanation:
<em><u>Showing the error</u></em>
-16-2(-2) – 12 First you need to multiply
8(-2) - 12 The error here is that the wrong numbers are multiplied together
-16-12 Add the negatives together
-28 Your answer (the incorrect one)
<em><u /></em>
<em><u>The correct way of solving it</u></em>
-16 -2(-2) - 12 Multiply into the parenthesis
-16 + 4 -12 Add the first two numbers
-12 - 12 Add the numbers together
-24 The answer
Answer:
the slope is 0.75
Step-by-step explanation:
you have to find the coordinate of each point then put them in acording to the formula in this case the coordinates are (-2,3) X1 and X2 and (-1,1)y1 and y2
Answer:
- increasing: (-∞, 0)
- decreasing: (0, ∞)
Step-by-step explanation:
The function goes up to the right until it gets to the vertex at x=0. Then it goes down to the right. That is, it is ...
increasing from -∞ to 0 (not including 0)
decreasing from 0 to +∞ (not including 0)
_____
At x=0, the function is neither increasing nor decreasing, so x=0 is not part of either interval.
2:3 is equivalent to 0.666 repeating

<span>2x^2 - 2x - 1 = 0 a = 2, b = -2, c = -1 b^2 - 4ac = (-2)^2 - 4(2)(-1) = 4 + 8 = 12
so the answer is 12
