Answer: 2(−5x^2
+9)(5x^2
+9)
Step-by-step explanation:
Given: 162-50x^4
Factor out 2: 2(81-25x^4)
Rewrite: 2(9^2-(5x^2)^2)
Use difference of squares: 2(9-5x^2)(9+5x^2)
Reorder (if you need to) 2(-5x^2+9)(5x^2+9)
Let's say "c" is a constant, hmmmm any constant, for any value whatsoever of "x", "y" is always that constant, for example, say c = 3, thus y = 3, so a table for it will look like
now, if you plot those points, it'd looks like the picture below.
Answer: (9, -2)
Step-by-step explanation:
Let's start with what makes a function even. A function is even if the graph of it is symmetric about the y-axis. What is really means is that if you were to fold your graph paper where the crease is on the y-axis, the graph should be the same on each side.
Now since g is an even function, it's correct for us to assume that it is symmetric about the y-axis. What this means is that we expect to find a value at the same point, except on the right side (because our coordinate is negative).
Our coordinate is (-9, -2). If we were to plot it, we'd see it would be in the 3rd quadrant, or the bottom left one. To be symmetrical on the right side, we know there is a point with the same coords in the 4th quadrant. To be on the right, our x coordinate would be positive, and our y coordinate will stay the same.
Answer:
6×7=42
Step-by-step explanation:
42 is 7 times as many as 6
is means equals and times means multiply
42 = 7*6
Changing the order
6*7 = 42
Answer:
-259
Step-by-step explanation:
16--259=
16+259 = 275
X = - 259
