Factor 2x squared plus 2x plus xy plus y?
4
What does 4x plus 3y-2x plus y equal?
4x+3y-2x+y 4x-2x+3y+y 2x+4y Taking out 2 common 2(x+2y) Hence the required answer is 2(x+2y)
Find the derivative for y equals 5-2x?
7
What is the intersection of these two lines 2x plus 4 equals y and x - y equals 2?
2x + 4 = y ...............2x + 4 = y ....................2x + 4 = y .............2*(-6)+ 4 = y x - y = 2 .......<=> ...x - 2x - 4 = 2 .....<=> ...x = -6......... <=>.... x = -6 ..............<=> y = - 8 x = - 6
Which of the following equations describe the line shown below for the points -4 5 and 1 -5 A y-5 -2 x plus 4 B y-1 -2 x plus 5 C y -2x-3 D y-4 -2 x plus 5 E y-5 -2 x plus 1 F y -2x-2?
What is the value of location on this number line? *Write your answer as 0.0XX
What is x plus 2y-2x-y equals .?
X + ( 2Y - 2X - Y ) is equal to Y - X
What is 2x-y equals 5 when x equals 4?
If x=4... then 'y' MUST equal 3 !
Y 2x plus 3 graph?
You can do the equation Y 2x plus 3 on a graph. On this graph the Y would equal 5 and X would equal to 0.
Y equals 2x y-x equals 5 using the sudstitution method?
-3
What is the x-intercept of y equals 2x plus 5?
The x intercept is where y = 0 y = 2x +5 = 0 2x + 5 = 0 2x = -5 x = -5/2 = -2.5
Where does y equals five and y equals negative two x plus three intersect?
y = 5y = -2x + 3Since both of those things are equal to 'y', they're equal to each other.5 = -2x + 3Add 2x to each side:5 + 2x = 3Subtract 5 from each side:2x = -2Divide each side by 2:x = -1The point of intersection is (-1, 5) .
Does y equals 2x - 4 and y equals 2x - 5 have a common solution?
y=2x-4 y=2x-5 y=1 1=2x-4 -2x = -5 x=2/5 the solution is (x,y) = (2/5,1)
What is 3x-2y-x?
5
What is the value of x and y in the simultaneous equations y equals x minus 1 and y equals 2x minus 5?
It follows that x - 1 = 2x - 5 as each expression is equal to y. Add 1 to each side: x = 2x - 4 Add 4 to each side: x + 4 = 2x Subtract x from each side: 4 = x y = x - 1 = 3
How do you rewrite this equation so that y is a function of x 2x plus y equals 5?
Solve for y.2x+y=5*subtract 2x from both sides*2x+y-2x=5-2xy=-2x+5 / y=5-2x
Solving 2x plus y equals 10 and y equals x-5 subtitution?
2x+x-5 = 10 2x+x = 10+5 3x = 15 x = 5 and y = 0
Work out 2x equals y plus 7 and x-2 equals y simultaneous equation?
2x = y + 7 x - 2 = y substitute the y from the second equation into the first: 2x = x - 2 + 7 2x = x+5 x = 5 --> y = 5 - 2 y = 3
