Because every x value cannot have more than one y value so doing it will make sure it has only one value on the line.
Answer:
There is no x-value that would lead to multiple y-values.
Step-by-step explanation:
PLATO answer
Hundreds because the answer is 251 so the 2 is in the hundreds
X^2-y^2=55
this means that
(x+y)(x-y)=55
we know that x-y=11 so we can write
(x+y)(11)=55
x+y=55/11 we divide by 11 and we obtain
x+y=5
x-y=11 this means
x=y+11 we replace in the other equation (x+y=5)
y+11+y=5
2y=5-11
2y=-6
y=-3
and you find out that also
x=8
Answer:
5 N.
Step-by-step explanation:
Given that,
A force vector M points 3 N in the x-direction and 4 N in the y-direction.
We need to find the magnitude of vector M. The magnitude of the vector when they are perpendicular to each other is given by :
So, the required magnitude of M is 5 N.
