Answer:
The output is -2 when the input is 3.
Step-by-step explanation:
You're actually being asked to evaluate y = -2x + 4 at x = 3. x is the 'input' and y is the 'output.'
At x = 3, y = -2(3) + 4 = -2
The output is -2 when the input is 3.
Note that when a point P(a, b) is reflected with respect to the y-axis, the y coordinate does not change, while a becomes -a.
So the reflection of a point P(a, b) with respect to the y-axis is the point P'(-a, b).
According to this, the projections of the points (2,3), (-4,-5), and (-2, 4) are the points the points (-2,3), (4,-5), and (2, 4).
Answer: A
Answer: The filled out table is shown in the attachment below
Row 1 = 2, 4, 8
Row 2 = 6, 36, 216
=======================================================
Explanation:
In the first row we have x^2 = 4. Apply the square root to both sides to get x = 2. It appears your teacher is making x positive.
So we'll have 2 in the first box of row 1.
If x = 2, then x^3 = 8 after cubing both sides.
In other words, x^3 = 2^3 = 2*2*2 = 8
The value 8 goes in the other box of row 1.
---------------
For row 2, we use x = 6 to square that to get x^2 = 6^2 = 6*6 = 36.
36 will go in the blank box for row 2
Answer:
I think you would have to add 12.5 to the 5
Step-by-step explanation:
120.25 I just divided the figure into smaller shapes, found the value and then I added the areas together! :)
