Add 4x to each side: 68 = 13x + 16
Subtract 16 from each side: 52 = 13x
Divide each side by 13: 4 = x
x + 16 = 9x Subtract 'x' from both sides x - x + 16 = 9x -x 16 = 8x Divide both sides by '8' 16/8 = 8x/x 2 = x or x = 2
16
40x+16=2540x=25-1640x=9x= 9/40x=0.225
it equals 13X.
The slope is 0.
x=-7
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
81x2 + 72x + 16 = 81x2 + 36x + 36x + 16 = 9x(9x + 4) + 4(9x + 4) = (9x + 4)2
16
9x^(2) + 16 DOES NOT factor. Remember ; two squared terms with a plus(+) between them DOES NOT factor However, two squared terms with a minus(-) between them DOES factor . Hence 9x^(2) + 16 = (3x)^2) + 4^(2) does NOT factor However, 9x^(2) - 16 = (3x)^2) - 4^(2) does factor to ( (3x - 4)(3x + 4) Note the two different signs.
