What is -5 y - 27?
-32
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.
If y equals 3 then y3 pararenthesis y3 minus y equals?
y=3 y^3(y^3-y)= 3^3(3^3-3)= 27(27-3)= 27(24)=648
The variables x and y vary directly when x equals -5 and y equals 21 what is the constant of variation?
y = kx k = y/x = 21/-5 = - 21/5
Ifx equals y equals 2z then what is the value of x?
y and ½z
If y equals 3xsquare-2x.then what is the y-value for x equals 3?
When x = 3, y = 3*32 - 2*3 = 27 - 6 = 21
If y equals -7 when XKE quarts -21 what is the value of X when Y equals nine?
14
If a equals 8 and a b equals 5 what is the value of y y equals 3a - b?
y = (3 X 8) - 5 = 21.
What is -5 y - 27?
-32
The sum of x and y is 27 If x equals 14 which equation can be used to find the value of y?
x+y=27 x=14 27-14=y y=13
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.
What is the value of x and y in 3x-y equals 21?
-18
If y equals 3 then y3 pararenthesis y3 minus y equals?
y=3 y^3(y^3-y)= 3^3(3^3-3)= 27(27-3)= 27(24)=648
The variables x and y vary directly when x equals -5 and y equals 21 what is the constant of variation?
y = kx k = y/x = 21/-5 = - 21/5
How do you solve 6x-6y plus 11 equals 17 6y equals 4x plus 21 in an order pair?
Rearrange the equations in the form of:- 6x-6y = 17-11 -4x+6y = 21 6x-6y = 6 -4x+6y = 21 Add both equatios together in order to eliminate y: 2x = 27 Divide both sides by 2: x = 13.5 Substitute the value of x into the equations to find the value of y: x = 13.5 and y = 12.5
What is the point of intrescetion of x-y equals 7and 3x plus y equals 9 using substitution?
x-y = 7 so x = 7+y 3x+y = 9 so 3(7+y)+y = 9 21+3y+y = 9 4y = 9-21 4y = -12 y = -3 Substitute the value of y into the original equations to find the value of x: Therefore: x= 4 and y = -3
What is x if y equals 21 for the equation y equals 4-3x?
