Answer:
15) (1, 1) and (-1, 1)
16) (1, 2) and (-1, 2)
17 (1,1/2) and (-1, 1/2)
18) (1,1/4) and (-1, 1/4)
19) 16 is vertical stretch, 17 and 18 is vertical compressed
Step-by-step explanation:
for qs 15-18 since x is 1 or -1 if you sq 1 or -1 you will always get 1
so y is the "a" value in the equation y=ax²
for qs 19
y=ax²
so if a>1 -- then vertical stretch
when 0<a<1 -- then vertical compressed

The new length is 180 feet because 30x6 is 180 and the new area is 900 cubic feet
Hello there!
Your answer is:
Length = 20
Width = 12

To solve this, we must make a system of equations.
<span>2L + 2W = 64
</span>
<span>L = (2W-4)
Now, we must plug (2W-4) into the first equation for l
2(2W-4) + 2w = 64
2 * 2w = 4w
2 * -4 = -8
4w - 8 + 2w = 64
6w - 8 = 64
Now let's solve this
6w - 8 = 64
+8 +8
6w = 72
Now, divide 72 by 6
72/6 = 12
w = 12
Now, we must plug 12 into the second equation into the w.
L = (2W-4)
L = 2 * 12 - 4
L = 24 - 4
L = 20
So, we know that L = 20 and w = 12
That means
Length = 20
Width = 12
Now, let's check this.
(12 * 2) + (20 * 2) = 64
12 * 2 = 24
24 + (20 * 2) = 64
20 * 2 = 40
24 + 40 = 64
24 + 40 = 64
64 = 64
I hope I helped!

You need 2 inequalities to solve this, one based on the NUMBER of printers and one based on MONEY. You will sell at least 100 printers, so your first inequality would be A+B>=100 (that's greater than or equal to). The second is based on the profit earned from each because the question in the end wants you to find how many you need to sell of each to make a profit of at least 3850. So the second inequality looks like this: 45A+35B>=3850. Solve the first inequality for A: A=100-B. Now sub this new A into the second inequality to get 45(100-B)+35B>=3850. Distribute to get 4500-45B+35B>=3850. Do the math to get that you need to sell 65 of B and 35 of A
