Answer:
20 and 16
Step-by-step explanation:
Let us find x and y.
x – y = 4 _____(1)
x/2 + y/2= 18___(2)
Multiply (2) by 2 and add to (1)
x - y = 4
+<u>(x + y = 36)</u>
<u>2x = 40</u>
=> x = 40 / 2 = 20
From (1):
20 - y = 4
=> y = 20 - 4 = 16
The two numbers are 20 and 16.
Answer:
y+4=2(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=2(x-4)
y+4=2(x-4) point slope form

Undefined.
Step-by-step explanation:
Comment
Let's begin by discussing why a calculator throws up and gives an error when Tan(pi/2) is entered.
Start by entering Tan(89) which is 1 degree from pi/2. The calculator is very well behaved when you do that, but look at how big Tan(89) is. 57.29. That's pretty big as these things go.
I was taught that the answer to Tan(pi/2) was infinity which I think is no longer in vogue. I think you should be answering Undefined.
