Plan an effective strategy for working through the course
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
Answer:
Thr answer is B.
Step-by-step explanation:
x-1^2 = x^2 - 2x +1
Using forming a square shape via formaticals, yes.
Answer:
x=-2, y=-2. (-2, -2).
Step-by-step explanation:
2x-5y=6
-2x+10y=-16
-------------------
5y=-10
y=-10/5=-2
2x-5(-2)=6
2x+10=6
2x=6-10
2x=-4
x=-4/2=-2
The distance between two points is calculated through the equation,
d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values from the given above,
d = √(4 - -4)² + (4 - -4)²
d = 8√2 = 11.31
The distance between the points is approximately equal to 11.31. The value that Jason presented is not the real distance because it does not account for the other set of coordinates.
