2018年4月24日 · 5x(x+4) The first thing you should always do whilst factoring is find a common factor. In this case, it would be 5x as it divides into both of these. Then take each variable and divide it by your factor. (5x^2) / (5x) = x (20x)/(5x) = 4 Then just put your factor on the outside of your bracket and the two other variables inside and you've got your answer! 5x(Your factor) …

2018年5月15日 · The slope is 1/2, and the y intercept is -2 First, you get y by itself. That gives you -10y=-5x+20. Then you divide both sides by -10. That gives you y=1/2x-2. The slope is the number with the variable and the y intercept is the other number.

2015年6月28日 · How do you solve #5x-20=5#? Algebra Linear Equations Two-Step Equations and Properties of Equality. 1 ...

2017年8月13日 · How do you find the x and y intercepts of #-5x+10y=20#? Algebra Graphs of Linear Equations and Functions Intercepts by Substitution. 1 Answer

2018年1月30日 · See a solution process below: First, subtract color(red)(20) from each side of the equation to isolate the x term while keeping the equation balanced: -5x + 20 ...

x=4, y=0 3x-y=12 5x+2y=20 We can start and find x by multiplying equation 1 by 2. 2(3x-y=12) 5x+2y=20 6x-2y=24 5x+2y=20 Now we can add both equations together and cancel the y' s. 6x-2y=24 11x=44 Therefore, x = 4. Now, we can back-substitute x to solve for y. 6(4)-2y=24 24-2y=24 -2y=0 y=1 Our solution set is (4, 1) or x = 4 and y = 1

2018年4月1日 · x-intercept: (4,0) y-intercept: (0,20) To determine the x-intercept, set y=0 in the equation and solve: 5x+0=20 x=20/5=4 The x-intercept is (4, 0).

2016年12月17日 · x +4 Product is the answer to a multiplication. The multiplicative inverse is the same as the reciprocal. (5x +20) xx 1/5 = (5x +20)/5 = x +4

2018年3月19日 · The standard form of a line is ax+by+c=0. If you were to change this into slope-intercept form, #y=mx+b#, your m would be the slope.
