WebTo find x intercept : 0 = ( x − 2) ( x 2 + 25) Now notice that ( x 2 + 25) > 0 ∀ x ∈ R and he factorization which you did is wrong. Thus 0 = ( x − 2) ( x 2 + 25) has only one root namely x = 2 hence that is the intercept. Note : x 2 > 0 ∀ x ∈ R and 25 being a positive integer we get that ( x 2 + 25) > 0 ∀ x ∈ R Share Cite Follow WebTo find the x x -intercept, let's substitute \pink y=\pink 0 y = 0 into the equation and solve for x x: \begin {aligned}3x+2\cdot\pink {0}&=5\\ 3x&=5\\ x&=\dfrac {5} {3}\end {aligned} 3x + 2 ⋅ 0 3x x = 5 = 5 = 35. So the x x -intercept is \left (\dfrac {5} {3},0\right) (35,0).

WebFind the equation of the line, which makes intercepts –4 and 5 on the x- and y-axes, respectively. Solution: Given, x-intercept = a = -4. y-intercept = b = 5. Equation of the line in intercept form is: (x/a) + (y/b) = 1. Substituting the values of a and b, we get the equation as: (x/-4) + (y/5) = 1. Or (-5x + 4y)/20 = 1-5x + 4y = 20. 5x ...
