2016年8月15日 · x= 3 or x = -2 All the numbers in the equation are even, so divide through by 2. x^2 - x - 6 = 0" find factors" The factors of 6 which subtract to make 1 are 2 and 2.

2015年9月11日 · The slope is -2/3. Convert the given equation to the slope-intercept form by solving for y. 2x+3y=12 is the standard form for a linear equation. To determine the slope, solve the equation for y in order to convert to the slope-intercept form y=mx+b, where m is the slope and b is the y-intercept. 2x+3y=12 Subtract 2x from both sides. 3y=-2x+12 Divide both sides …

2018年3月20日 · By rebuilding it to an easier formula. This formula can be "rebuild" into the regular form of y = a*x + b We substract 2x from each side of the equation, we then get; 3y = -2x + 12 We then divide everything by 3. The formula then looks like this; y = (-2/3 * x) + 12, which you should be able to graph.

2017年12月25日 · For example: y=\log(2x-12) y = \log_{10}(2x-12) This can be represented by, in exponential form, 10^y = 2x - 12 10 raised to any exponent cannot get a negative number or be equal to zero, thus 2x - 12 > 0 So solve 2x - 12 > 0 to get the permissible values for x. 2x - 12 > 0 \ \ \ \ \ \ \ \ \ 2x > 12 \ \ \ \ \ \ \ \ \ \ \ x > 6 The domain is \{x ...

2018年6月23日 · See a solution process below: First, group and combine like terms on the left side of the equation: 2x + 12 - 7x = -2 2x - 7x + 12 = -2 (2 - 7)x + 12 = -2 -5x + 12 = -2 Next, subtract color(red)(12) from each side of the equation to isolate the x term while keeping the equation balanced: -5x + 12 - color(red)(12) = -2 - color(red)(12) -5x + 0 = -14 -5x = -14 Now, …

2017年3月12日 · How do you find the vertex, x-intercept, y-intercept, and graph the equation #y=-4x^2+20x-24

2015年9月16日 · How do you write #4x^2+2x-12# in factored form? Algebra Polynomials and Factoring Factoring Completely. 1 ...

2018年4月1日 · Slope (m)=2/3 We can determine our slope by changing this equation to slope-intercept form, y=mx+b, where m is our slope. We have 2x-3y=12 We can start by subtracting 2x from both sides to get: -3y=-2x+12 Our last step would be to divide both sides of the equation by -3. We get: y=2/3x-4 When we're in slope-intercept form, the slope is the coefficient on the x …

2015年2月3日 · We can use the Sum-Product method. Bring everything to one side: x^2-x=12->x^2-x-12=0 We now have a quadratic equation of the form ax^2+bx+c=0 where a=1, b=-1 and c=-12 We find two numbers that will give c=-12 as a product and b=-1 as a sum (or difference). We can try 1*12, 2*6,3*4 3and4 will fit, with a -sign to the 4, as that would make the sum 3-4= …
