What is the y intercept of 4x plus 8y equals 16?
Solve for Y algebraically. 4X + 8Y = 16 8Y = - 4X + 16 Y = - 1/2X + 2 graph and see that the Y intercept = 2
4x plus y equals 7 2x-3y equals -7?
(A): 4x + y = 7 (B): 2x - 3y = -7 2*(B) 4x - 6y = -14 Subtract from (A) 7y = 21 Divide both sides by 7: y = 3 Substitute in (A): 4x + 3 = 7 ie 4x = 4 or x = 1 Answer: x = 1 , y = 3
What graph could be used to find the solution of the system of equations y equals 2x plus 6 and y equals x2 plus 4x plus 3?
A graph that has 1 parabolla that has a minimum and 1 positive line.
Is 8 plus y equals 4x a linear equation?
Yes.
What is the derivative of y equals square root of 8x plus square root of 4x?
y=(8x).5 + (4x).5 = (2+2sqrt(2))x.5 y'=(1 + sqrt(2))/sqrt(x)
-y equals 4x plus 1 4x plus y equals 2?
2
What is the x-intercept of y equals -4x plus 4?
x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept
4x - y equals 1 3x plus y equals 13?
(2, 7)
Where does the y equals 4X plus 1 cross the y axis?
when x = -0.25
What is the ordered pair for y equals -4x plus 2 y equals x-3?
(1,-2)
Y equals -x2 plus 4x-3?
y = 4x-3
What is the substitution of4x plus 4y equals 16 and y equals 5?
4x+4y=16 y=5 4x+ 20=16 4x=-4 x=-1
4x plus y equals 9 7x - 8y equals 6?
(2, 1)
What is the x-intercept in this eqution y equals -4x plus 4?
y = -4x + 4 x intercept is where y = 0 0 = -4x +4 4x = 4 x = 1
Which equation is equivalent to 4x plus y equals 12?
It is: y = -4x+12
What is the solution for y equals 4x and x plus y equals 5?
So substitute for y : x + 4x = 5 so 5x = 5, so x=1, y=4
Is y equals 4x plus 5 parallel or perpndicular to -4x plus y equals -13?
Parallel, the slope of the second equation is 4
