Step-by-step explanation:
Answer:
I am pretty sure that you just make the line steeper than the others, nothing specifically. I'm learning this in middle school and I would appreciate if someone else could specify on why
Step-by-step explanation:
Answer:
-3, -33
Step-by-step explanation:
We have that J and K are points on the number line.
K is at -18 and JK has a value of 15.
They ask us to find the point where J. finds.
J can take two locations depending on whether we move it to the left or right of the number line.
If J is on the left side of K, then the location would be:
-18 + 15 = - 3
If J is on the right side of K, then the location would be
-18 - 15 = -33
Which means that J is at -3 or -33
-3, -33
Xy = -900
x + y = 5
x + y = 5
x - x + y = -x + 5
y = -x + 5
xy = -900
x(-x + 5) = -900
x(-x) + x(5) = -900
-x² + 5x = -900
-x² + 5x + 900 = 0
-1(x²) - 1(-5x) - 1(-900) = 0
-1(x² - 5x - 900) = 0
-1 -1
x² - 5x - 900 = 0
x = -(-5) ± √((-5)² - 4(1)(-900))
2(1)
x = 5 ± √(25 + 3600)
2
x = 5 ± √(3625)
2
x = 5 ± 5√(145)
2
x = 2.5 ± 2.5√(145)
x + y = 5
2.5 ± 2.5 √(145) + y = 5
- (2.5 ± 2.5√(145) - (2.5 ± 2.5√(145)
y = 2.5 ± 2.5√(145)
(x, y) = (2.5 ± 2.5√(145), 2.5 ± 2.5√(145))
The two numbers that add up to 5 and multiply to -900 are 2.5 ± 2.5√(145).
