How do you find the difference 28y-16y?
28y - 16y = 12y.
X-3y equals 7 -3x plus 16y equals 28?
-3x+16y = 28 3(x-3y = 7) Multiply the bottom equation by 3 then add both equations together in order to eliminate x: 7y = 49 y = 7 Substitute the value of y into the original to find the value of x: So: x = 28 and y = 7
What is the parabola fo y equals 4-16y-11?
The equation does not represent that of a parabola.

Solve the system 4x-3y equals 11 and 5x plus 4y equals 6?
5(4x-3y = 11) 4(5x+4y = 6) Multiply the top equation by 5 and the bottom by 4: 20x-15y = 55 20x+16y = 24 Subtract: -31y = 31 y = -1 Substitute the value of y into the original equations to find the value of x: So: x = 2 and y -1
What is the value 16y 164?
Find the value of y in this equation: 16y = 164.Answer: 10 1/4
Find the value of y in this equation 16y equals 164?
16y = 164 y = 164/16 = 82/8 = 41/4 = 10.25
How do you find the difference 28y-16y?
28y - 16y = 12y.
X-3y equals 7 -3x plus 16y equals 28?
-3x+16y = 28 3(x-3y = 7) Multiply the bottom equation by 3 then add both equations together in order to eliminate x: 7y = 49 y = 7 Substitute the value of y into the original to find the value of x: So: x = 28 and y = 7
What is the parabola fo y equals 4-16y-11?
The equation does not represent that of a parabola.
5x-4y equals -41 4x plus 35 equals?
5x - 4y = -41 => 5x = 4y - 41 => x = (4y - 41)/5 Then 4x + 35 = 4*[(4y - 41)/5] + 35 = 16y/5 - 164/5 + 35 = 16y/5 -11/5 or (16y - 11)/5
3x plus 4y equals 90 4x-3y equals -5?
This is a simultaneous equation question. 4(3x+4y = 90) 3(4x-3y = -5) Multiply the top equation by 4 and the bottom equation by 3 then subtract the bottom equation from the top equation remembering that in maths a minus from a minus is equal to a plus. 12x+16y = 360 12x-9y = -15 And when subtracted: 0+25y = 375 Divide both sides of the equation by 25 to find the value of y: y = 15 Substitute 15 for y into the original equation to find the value of x: Solution: x = 10 and y = 15

What is the difference 28y- 16y?
It is: 28y -16y = 12y
What is 16y -64 as an inequality?
16y -64 as an inequality = -48
What is the equation of a circle centered at the origin with a radius of 3 over 4?
x² + y² = 9/16 or 16x² + 16y² = 9
