Which ratios are equivalent to 12:24? I have to select each correct answer.

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Find the value of x. give reasons to justify your solutions! l, m ∈ kn
