2xy x equals 5 y equals 3?
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
What is the answer to this math question 3xy-xy-2y plus 5y?
That equals 2xy + 3y which factors to y(2x + 3)
What is the answer of 2xy plus y-3xy?
-1
Is y equals x over 7 a direct variation?
y=x/7 y=(1/7) x It is a direct variation since it is of the form y=kx, where k=1/7 , a constant
What is the slope y equals -2x plus 7?
When an equation is in the form y = mx + b, it is known as slope-y-intercept form. Here, m is the slope and b is the y intercept. So, the slope in the equation y = -2x + 7 is -2.
2xy x equals 5 y equals 3?
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
Evaluate 2xy when x equals 30 and y equals 2?
2xy=2*30*2=120
When x-y equals 7 and xy equals 8 find the value of x square plus y square?
x2 + y2 = x2 - 2xy + y2 + 2xy = (x - y)2 + 2xy = 72 + 2*8 = 49 + 16 = 65 You could, instead, solve the two equations for x and y and substitute, but the above method is simpler.
Does 6xy-8xy equals -2x squared y squared?
No, it equals -2xy. lrn2math
What is the value of 2xy if x2 and y7?
2xy x is 2 y is 7 therefore (2)(2)(7) = 28
Why cant 2x plus y equals 2xy?
Because 2x+y is addition not multiplication
2cy plus 2xy equals 15 solve for y?
Y=15/(2c+2x)
How do you evaluate 2xy times 9 if x equals 3 and y equals 2?
2xy*9 if x=3 and y = 2 2(3)(2)*9 12*9 108 You substitute x and y for their equivalent (3 and 2) then simply multiply 2*x*y, then multiply the answer of that by 9.
How do you factorise 2xy - 6x plus 7y -21?
2x(y - 3) + 7(y - 3) = (2x + 7)(y - 3)
Write x plus 7 equals y in standard form?
y = x + 7
If Y' equals 2xy plus x to power 3 what is y equal to?
Assuming y' is dy/dx, y = x^4/4 + yx^2
What is the slope-intercept form of the equation -2x plus y equals 7?
y=2x+7. The 2 is your slope and the 7 is your y intercept.
