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:
513 turkey sandwiches were sold.
Step-by-step explanation:
Let's use 
to represent turkey sandwiches and 
to represent steak sandwiches.
= turkey sandwiches
= steak sandwiches
total sandwiches that were sold
dollars that were made
Now that we know what (steak sandwiches) equals, we plug it in to an equation to find .
Now, we subtract 5,550 from BOTH sides so we can get x by itself.
Next, we divide both sides by 2, so x is bare.
Since x represents turkey sandwiches, we have our answer: 513 turkey sandwiches were sold.
I hope this helps! :)
Answer:
√7 is less than 14/5
Step-by-step explanation:
√7 equals about 2.6
14/5 equals 2.8
Answer:
We need to find the value of b to make 8b - 27 be equal to 5, so:
8b - 27 = 5
We solve the equation:
8b = 5 + 27
8b = 32
We divide both sides by 8:
b = 32/8 = 4
So now, we know that b=4, and we can verify:
8*4 - 27 = 5
32 - 27 = 5 TRUE
