Answer: y = 2/5 x + 2
Step-by-step explanation:
why not do this one too yk
slope = y2 - y1 / x2 - x1
4 - 2 / 5 - 0
slope = 2/5
ill use (5,4) for the y=mx+b initial equation
y = mx+b
4 = (2/5)(5) +b
4 = 2 + b
2 = b
now for the final equation whoop whoop
y = 2/5 x + 2
Answer:
v=a+ 2e1= [3 1 1 1]
.
Step-by-step explanation:
Let a = 
and we know that
=±║α║₂= 2.
As we have gone over in class, the formula for v is v= a-
e1
with the sign of chosen to avoid subtraction. This gives v=a+ 2e1= [3 1 1 1]
.

Answer:
D(6, 3)
Step-by-step explanation:
The diagonals of a rectangle bisect each other, so the midpoint of AC is the same as the midpoint of BD. This means ...
(A +C)/2 = (B +D)/2 . . . . the midpoints are the same
A +C = B +D . . . . . . . . . multiply by 2
D = A +C -B = (2+5-2, 1+5-3) . . . . . solve for D, substitute given coordinates
D = (6, 3)
Answer:
The final answers are x = 1 OR x = -3.
Step-by-step explanation:
Given the equation is x^2 -3 = -2x
Rewriting it in quadratic form as:- x^2 +2x -3 = 0.
a = 1, b = 2, c = -3.
Using Quadratic formula as follows:- x = ( -b ± √(b² -4ac) ) / (2a)
x = ( -2 ± √(4 -4*1*-3) ) / (2*1)
x = ( -2 ± √(4 +12) ) / (2)
x = ( -2 ± √(16) ) / (2)
x = ( -2 ± 4 ) / (2)
x = (-2+4) / (2) OR x = (-2-4) / (2)
x = 2/2 OR x = -6/2
x = 1 OR x = -3
Hence, final answers are x = 1 OR x = -3.
