what is 3x-x | Wyzant Ask An Expert what is 3x-x Need Math Help I want to ask questions about math problems that i don't understood For example, Equations, Distribute numbers, and Simplify Expressions
How do you solve y−3x=13 for y in the easiest possible way? When it says solve for y it just means get y by itself on one side The easiest way to achieve this is by getting rid of the 3x Since the 3x is being subtracted from y, we must do the opposite (add 3x) to both sides: y - 3x = 13 +3x +3x y = 3x + 13 If you have any questions don't hesitate to reach out!
How do you solve 2x^2+3x-2=0 | Wyzant Ask An Expert 2x 2 + 3x - 2 = 0 Here you have a quadratic equation with one unknown variable (x) Since the equation is set equal to 0, we solve for it by factoring the left hand side of the equation and then apply the zero product property to solve for the unknown variable (x) Factoring: 2x 2 + 3x - 2 = 0 (2x - 1) (x + 2) = 0
How do you solve and plot the points for y=3x-1 - Wyzant The x- and y-coordinates are values of the points on the line of y = 3x - 1 ) 2) Identify the m (slope) and the b (y-intercept) The slope is 3, which can also be written as 3 1 The y-intercept is -1 (Remember that subtraction of 1 is the SAME thing as adding -1!) Since the y-intercept is a point it will be plotted at (0, -1)
Use the function f (x) to answer the questions: f (x) = 2x2 − 3x − 5 A: Let f (x) = 0 and solve for x to get the x intercepts 2x 2 -3x -5 =0 Factor to get (2x -5) (x + 1) =0 then 2x - 5 = 0 and x = 2 5 x + 1 = 0 and x = -1 These are the x intercepts B: As the coefficient of the x^2 term is positive, the parabola open up, and the vertex is a minimum The coordinates of the parabola are given by -b 2a, f ( -b 2a) where a and b represent the coefficients of a
Which line is parallel to the line y=3x-2? - Wyzant Arthur, We take a look at the general equation y = mx + b where m is the slope of the line For lines to be parallel, the slope must be equal, therefore, we try to find where m is the same on both equations Answer: a) y=3x-8
