y-42x = 24
>> Add 42x to both sides <<
y=24+42x
>> Subtract 24 from both sides <<
y-24=42x
>> Divine both sides by 42 <<
x=(y-24)/42
So y = (3x - 4)/2. To find the find the inverse equation, y-1,(1) Rewrite the equation replacing all ys with xs and all xs with ys.x = (3y - 4)/2(2) Solve the new equation for yx = (3y - 4)/22x = 3y - 42x + 4 = 3y(2x + 4)/3 = yThis is your inverse equation!y-1 = (2x + 4)/3
5x + 32 = 11x - 105x - 11x = -10 - 32-6x = -42x = 7
To find the extreme value of the parabola y = x2 - 4x + 3 ...(1) Take the derivative of the equation.y = x2 - 4x + 3y' = 2x - 4(2) Set the derivative = 0 and solve for x.y' = 2x - 40 = 2x - 42x = 4x = 4/2x = 2(3) Plug this x value back into the original equation to find the associated y coordinate.x = 2y = x2 - 4x + 3y = (2)2 - 4(2) + 3y = 4 - 8 + 3y = -1So the vertex is at (2, -1).
Given: 2X + 2Y = 42X + Y = 42/2X + Y = 211 + 20 =212 + 19 =213 + 18 =214 + 17 =215 + 16 =216 + 15 =217 + 14 =218 + 13 =219 + 12 =2110 + 11 =21Given: XY = 1048 x 13 = 104X=8, 13Y=13, 8
the volume of the box would be 4x^3-42x^2+80x since a volume wasn't given to find 'x' or a set 'x' wasn't given, that is the equation you would use
−39x−6
Without an equality sign the expession given is not an equation. But if you mean 8 = 42x then the value od x is 8/42
x2 - 42x + 441 = (x - 21)2
P = Cx 'P' = the product 'C' = any integer
42x+35x-35x=42x it's leave 85 so it's change into a negative 42x-85 is the answer
So y = (3x - 4)/2. To find the find the inverse equation, y-1,(1) Rewrite the equation replacing all ys with xs and all xs with ys.x = (3y - 4)/2(2) Solve the new equation for yx = (3y - 4)/22x = 3y - 42x + 4 = 3y(2x + 4)/3 = yThis is your inverse equation!y-1 = (2x + 4)/3
hujkImproved anwser:2x+6 = 7x-42x-7x = -4-6-5x = -10x = 2
7x=42x=42/7x=6
-1/19=x
42x + 1 = 8x - 1Subtract 1 from each side:42x = 8x - 2Subtract 8x from each side:34x = -2Divide each side by 34:x = -2/34 = -1/17
-8 + 7x = x - 506x = -42x = -6
x+5/7 = 11/6 Multiply all terms by 42: 42x+30 = 77 42x = 77-30 42x = 47 Divide both sides by 42: x = 47/42
