Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
When you want to find out what the slope is, you have to remember what the formula is first....
so in this case -3 would be the 
because it's the y in the ordered pair and it's the second one. Then one of the 5's would be 
and 9 would be 
and then the other 5 would be 
.
now if we plug it in
now we can tell that we can't divide by zero so the slope would be unidentified and that's it.
Answer:
10, 14
Step-by-step explanation:
take the x values and plug into mid point formula and then divide by 2
so... (-214 + 234) divided by 2 = 10
do the same for the y values
so ... (14 + 14) divided by 2 = 14
so ... 10,14
Answer:
Step-by-step explanation:
- (x+y-z)²= 4xy
- (x+y-z)²- 4xy = 0
- (x+y-z)²-(2√x√y)² = 0
- (x+y-z-2√x√y)(x+y-z+2√x√y) =0
- [(√x-√y)²-z]*[(√x+√y)²-z]=0
- (√x-√y)²-z = 0 or (√x+√y)²-z = 0
We have : z^(1/2)= x^(1/2)+y^(1/2) ⇒ √z = √x + √y ⇒ z = (√x + √y)²
so (x+y-z)²= 4xy
