If y equals 3 then y3 y3-y equals?
y3 x y3 - y (3)3 x 3(3) - 3 9 x 9 - 3 = ? 9 x 9= 81 81 - 3 = 78 I hope that solves your problem
Find the inverse variation equation if x equals 5 when y equals 9?
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
If y varies inversely as the square of x and y equals 5 when x equals 2.5 what is the value of y when x equals 9?
So 5 = (xy)^2 and x = 2.5. This means that 5 = (2.5y)^2. So sqrt(5)/2.5 = y when x = 2.5. Now if x = 9 then 5 = (9y)^2. So sqrt(5)/9 = y. This means that for any x in this relation y = sqrt(5)/x.
Answer to x plus 9y equals 18?
x=9 y=1
A number y varies inversely as the square of x If y equals 2 when x equals 6 what is y when x equals 3?
x2y = k (constant) so 36 x 2 ie 72 is the constant. If x = 3 then y = 72/9 = 8
What does y equals 3x plus y and y equals x-9 equal?
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
What is the answer to y equals x plus 9?
y=x+9 y'=1 x+9=0 x=-9 y=-9+9 y=0
If y equals 6x and x equals 1.5 what is y?
y=9
What is the expression which connects y and x when y is inversely proportional to x and x equals 9 y equals 7. and what is the value of y when x equals 21?
x*y = k where k is a constant.When x = 9, y = 7 so k = 9*7 = 63 When x = 21, 21*y = 63 so y = 3.
How do you Substitute x equals y plus 3 into x plus 2y equals 9?
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
What is the Y intercept of X plus Y equals nine?
If: x+y = 9 then y = -x+9 whereas the slope is -1 and the y intercept is 9
X plus y equals 10 and y equals x plus 8?
(1, 9)
What happens to the graph of y equals x when the equation changes to y equals x - 9?
The graph shifts downward (negative y) by 9 units.
What is the x and y intercept for x plus 3y equals -9?
-6
Y equals 10x - 9 y equals x plus 18?
(3,21)
2x plus 3y equals 13 x -y equals 9?
x = 8, y = -1
What is the x-intercept of y equals 6x-9?
