6y + 5
If you mean 8y-2y = 132 then 6y = 132 and the value of y is 22
Not sure which you mean, take your pick: (8y)3+27=(8y+3)((8y)2-3*(8y)+9)=(8y+3)(64y2-24y+9); or 8y3+27=(2y+3)(4y2-6y+9)
Y = 1.125 2Y + 6Y - 9 = 0 2Y + 6Y = 9 Y(2+6) = 9 8Y = 9 Y = 9/8 = 1 1/8 = 1.125 PROOF: 2(1.125) + 6(1.125) - 9 = 0 2.5 + 7.5 - 9 = 0 9 - 9 = 0
4y + 8y = 12y 4y - 8y = -4y 4y x 8y = 32y2 4y/8y = 1/2
6y-8y = -2
9y-3y=6y; 6y+2y=8y; so your answer is 8y
6y + 5
If you mean 8y-2y = 132 then 6y = 132 and the value of y is 22
8y+6y is 14y
y = -1
Not sure which you mean, take your pick: (8y)3+27=(8y+3)((8y)2-3*(8y)+9)=(8y+3)(64y2-24y+9); or 8y3+27=(2y+3)(4y2-6y+9)
Oh, dude, math time! So, you've got 8y + 4x + 6y. Just like mixing different sodas at the fountain, you can combine like terms here. So, that gives you 14y + 4x. Ta-da! Math magic.
8y-7x
The answer depends on the value of y. For example, when y = 0, 8y2 + 6y - 2 = -2 when y = 1, it is 12
12y + 2 or 2*(6y+ 1)
