Answer: 17
Step-by-step explanation: a numerical or constant quantity placed before and multiplying the variable in an algebraic equation
The points which are reflections of each other across the y-axis are (–7, –3) → (7, –3) and (–5, 4) → (5, –4)
A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection. A figure is said to reflect the other figure, and then every point in a figure is equidistant from each corresponding point in another figure.
Given are some points, (–7, –3) and (7, –3) (–5, 4) and (5, –4) (1, –8) and (1, 8) (–3, 5) and (5, –3)
We need to find which one of them are reflections of each other across the y-axis,
We know that, rule of reflection over y-axis,
(x, y) = (-x, y)
Therefore, from the given points, the points that are following the rule of reflection over y-axis, are (–7, –3) → (7, –3) and (–5, 4) → (5, –4)
In both of these points, the x-coordinate is changing its sign.
Hence, the points which are reflections of each other across the y-axis are (–7, –3) → (7, –3) and (–5, 4) → (5, –4)

Rule for reflecting over the y-axis: P(x, y)--->P'(-x, y), so the answer is (–7, –3) and (7, –3). You might think the answer would be (–5, 4) and (5, –4) but it is not because (–5, 4) reflected across the y-axis is (5, -4).
Answer:
5
Step-by-step explanation:
5 minus 5 equals 0
0 times 5 equals 0
0 plus 5 equals 5
Answer:
the answer is five
Step-by-step explanation:
5 minus 5 equals 0
0 multipled by 5 equals 0
0 plus 5 equals 5
this is the answer 5
Greetings!
You can solve this with a simple equation:
Take the letter x to be the unknown number:
20 = 8+ (X + 5)
Then you can move the 8 + to the opposite side making it a negative 8:
20-8 = X + 5
12 = X + 5
Move the +5 over to the other side, making it a negative 5:
12 - 5 = x
7 = x
So the value of x is 7.
Hope this helps!
Out of 1000 calls, 15% were not answered. To find this as a number, we multiply 1000 by 0.15 (the decimal equivalent of 15%). This calculation gives us the result of 150 calls not answered.
The question asks about the number of calls that were unanswered out of 1000 calls being sent out. From the presented problem, it is clear that only 15% of the calls were unanswered. To find how many calls this 15% represents, we just need to calculate 15% of 1000:
To find 15% of a number, we multiply the number by 0.15 (the decimal equivalent of 15%).
So, 1000 * 0.15 = 150 calls.
Therefore, out of 1000 calls sent out, 150 of them were not answered.
