9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
Solve for Y algebraically. 4X + 8Y = 16 8Y = - 4X + 16 Y = - 1/2X + 2 graph and see that the Y intercept = 2
x = 8y, which cannot be simplified any further, unless solving for y, which would be y = x/8.
2x = -7 - 8y
-8y+9=18y-4Add 8y to both sides.9=26y-4Add 4 to both sides.13=26yDivide 13 by 26.1/2=y or 0.5=y
(2, 1)
y=4
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
-8x-8y=-64 -8y=8x-64 y=-x+8
If y = 2, then 8y = 8 x 2 = 16.
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
Y- intercept of 4x+8y=16
If you mean y2+8y+7=0 then it is a quadratic. y2+8y+7+9-9=0 y2+8y+16-9=0 (y+4)2=9 y+4=3 , y+4=-3 y=-1 , y=-7 So y can equal -1 or -7.
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
