Answer: 3y - 8x + 2 = 0
Step-by-step explanation:
The formula is
y - y₁ y₂ - y₁
------- = ---------- where x₁ = -2, x₂ = 1, y₁ = -6, y₂ = 2,
x - x₁ x₂ - x₁
Now we substitute for the values in the above equation and then solve.
y - (-6) 2 - (-6) 2 + 6 8
---------- = ----------- = --------- = ----
x - (-2) 1 - (-2) 1 + 2 3
y + 6 8
-------- = ---- , we now cross multiply to get the required equation.
x + 2 3
3( y + 6 ) = 8( x + 2 )
3y + 18 = 8x + 16
3y - 8x + 18 - 16 = 0
3y - 8x + 2 = 0
Answer:
104
Step-by-step explanation:
100%= 1.00
so
420%= 4.20
Multiply 4.20×20
84
now add the original 20

Answer:
3x^2 + 7x - 5 + 2x^2
= 5x^2 + 7x - 5 (a=5, b=7, c=-5)
x = (-b+/- √(b^2 - 4ac))/2a
= (-7+/- √(49+100))/10
= (-7+√149)/10, (-7-√149)/10
Hope this helps!
No because mixed numbers need atleast a one and a fraction to be a mixed number. But if there was a fraction then it couldn't equal two, because of the 1's ❤️
