Hello :
y= <span>x² - 4x + 1
calculate : x
y = (x²-4x+4)-4+1
y+3 = (x-2)²
x exist : if y+3 </span><span>≥ 0
y </span><span>≥ -3
the range is : </span><span>{y: y ≥ -3}</span>
Answer:
Coprime numbers (relatively prime). Numbers have no common prime factors.
Answer:
A, C, D
Step-by-step explanation:
In a proportional relationship, y = kx, k is the constant of proportionality.
A)
4y = x
y = 1/4 x
k = 1/4 Yes
B)
y = 4x
k = 4 No
C)
32y = 8x
y = 8/32 x
y = 1/4 x
k = 1/4 Yes
D)
y = 0.25x
k = 0.25 = 1/4 Yes
E)
1/4 y = 2x
y = 4 * 2x
y = 8x
k = 8 No
Answer: A, C, D
-3 = 5 - 4x
Add both sides by 4x
4x - 3 = 5
Add both sides by 3
4x = 8
Divide both sides by 4
x = 2
That's your answer. Have an awesome day! :)
