Answer:
Step-by-step explanation:
as if we form an imaginary triangle with this line as hypotenuse
we get
- base = 3 units
- perpendicular = 4 units
using Pythagoras theorem:-
hyponteuse ² = perpendicular ² + base²
hyp² = 4² + 3²
hyp² = 16 + 9
hyp = 5 units
Is there an image, or shape that this is?
Answer:
a point
Step-by-step explanation:
Answer:
x=1+√5 or x=1−√5
Step-by-step explanation:
Let's solve your equation step-by-step.
x2−2x−4=0
Step 1: Use quadratic formula with a=1, b=-2, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−2)±√(−2)2−4(1)(−4)
2(1)
x=
2±√20
2
x=1+√5 or x=1−√5
Hope this helps!! :D Happy Tuesday!
Answer:
y = kx
Step-by-step explanation:
Y is directly proportional to x if the relation can be written using the equation ...
y = kx . . . . . for some constant k
__
Note that k may be positive or negative. The graph of this equation is a straight line through the origin.
The value of k can be found from corresponding values of x and y using ...
k = y/x
This is also another way to express the fact that x and y are proportional.
