Step-by-step explanation:
let use x as 'a number'
6 (9+x)
or
6 * (x+9)
Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with -3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format: +bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
PS= 21.37 (2dp)
CDB=68.74 degrees to 2dp
Y - 6 = -4 ( x - 3 )
Distribute -4 inside the parenthesis)
y - 6 = -4x + 12 (negative × negative = positive)
take -6 to the other side
y - 6 (+6) = -4x + 12 (+6)
y = -4x + 18
