it became 3t^2
15
ur answer is t= -23 -23 x 3= -69 + 46 = -23
3
x = 3
You're looking to combine these two equations into one that uses only the terms x and y, right? In that case, we can take either of those equations, solve it for t, and plug it's results in place of t in the other equation: x = -3t + 4 y = t + 1 y - 1 = t x = -3(y - 1) + 4 x = -3y + 3 + 4 x = 7 - 3y You can of course solve this for y as well: -3y = x - 7 y = (7 - x) / 3
To solve the equation 5 - 8x = 7t when x = 1 and t = -3, substitute the values of x and t into the equation. 5 - 8(1) = 7(-3) 5 - 8 = -21 -3 = -21 Therefore, the equation is not true when x = 1 and t = -3.
T/y = x/wMultiply each side by 'x':Tw/y = x
You solve ___x 3 by adding the number you are multiplying 3 times!
3^6 = 729
(x-3)(x+2)the answer is x=3
The equation to solve is given by. |-2 x + 2| -3 = -3 Add 3 to both sides of the equation and simplify. |-2 x + 2| = 0 |-2 x + 2| is equal to 0 if -2 x + 2 = 0. Solve for x to obtain. So, x = 1
(-x)2 = 3=> -x = ±√3=> x = -√3 and x = √3
