Factor the expression by grouping 5x 2-10x plus 5xy-10y?
5x(x - 2) + 5y(x - 2) = (5x + 5y)(x - 2) = 5(x - 2)(x + y)
What are the x and y intercepts of -2x equals 20 plus 5y?
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
How do you find the solutions of the simultaneous equations of 2x plus 5y equals 16 and -5x-2y equals 2 showing work in step by step stages?
1 If: 2x+5y = 16 and -5x-2y = 2 2 Then: 2*(2x+5y =16) and 5*(-5x-2y = 2) is equvalent to the above equations 3 Thus: 4x+10y = 32 and -25x-10y = 10 4 Adding both equations: -21x = 42 or x = -2 5 Solutions by substitution: x = -2 and y = 4
What is 5x equals 4x plus 7?
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
Simplify 7x plus 5x equals?
It is: 12x
What does x mean in the equation 10y equals 5x plus 95x?
Do not write an equation in words!!! What does x mean in 10y = 5x + 95x? It is a place holder for a number. Any number.
What is the answer to -10y-5x equals -20?
Write out equation - 10y - 5x= - 20 Negate equation 10y + 5x = 20 Isolate y variable 10y = - 5x + 20 Divide equation by 10 y= -1/2x + 2
What is 10y plus 40?
10y plus 40 equals 50y.
Graph this equation 5x plus 10y equals 20?
for the equation:5x + 10y = 20, the two intercepts are:x = 0 , y = 2 or (0,2)y = 0 , x = 4 or (4,0)The graph is a straight line passing through the two intercepts (0,2) and (4,0)
10y equals 2y plus 4 plus 7y?
10y = 9y + 4, so y = 4
How do you find the x and y intercept of -5x plus 10y equals 20?
Basically, the x-intercept is what x equals when y=0, and the y-intercept is what y equals when x=0. To find the x intercept, set y equal to 0. -5x+10(0)=20 -5x+0=20 -5x=20 divide both sides by -5 x=-4 so the x intercept is (-4,0) To find the y intercept, set x equal to 0. -5(0)+10y=20 0+10y=20 10y=20 divide both sides by 10 y=2 so the y intercept is (0,2)
How do you write 5x - 10y equals 3 in slope intercept form?
y = 0.5x - 0.3
What is 10y squared -23y plus 9 factorised?
(5x-9)(2x-1) when factored
If 8x plus 5x plus 2x plus 4x equals 114 the 5x plus 3 equals?
33
Can you show me how to solve graphically 3x plus 4y equals 5 and x-2Y equals 5?
3x + 4y = 5x - 2y = 5leads to:x = 5 + 2ySo:3(5 + 2y) + 4y = 515 + 10y = 510y= -10y=-1and therefore if y = -1 then x = 3.
Y-8x plus 9y equals?
Y-8x plus 9y equals 10y-8x.
Y2 plus 10y plus 25 equals 0?
yes that is correct
