Direct Variation - Algebra - Socratic
#y=kx#, where #k# is the constant of proportionality. If you solve for #k#, we have. #k=y/x#, which is the ratio of #y# to #x#. Hence, the constant of proportionality is the ratio between two quantities that are directly proportional.
What is the constant of proportionality "k"? - Socratic
2014年11月11日 · Direct Variation If y is directly proportional to x, then we can write y=kx, where k is the constant of proportionality. If you solve for k, we have k=y/x, which is the ratio of y to x. Hence, the constant of proportionality is the ratio between two quantities that are directly proportional. Inverse Variation If y is inversely proportional to x, then we can write y=k/x, …
Find k if the line y = kx-5 passes through the point ( -2,3)
2016年4月7日 · The line y=kx-5 is given in slope-intercept form [y=mx+b, where m is slope and (0,b) is the y-intercept].
Derive equation y=kx that cuts through a given circle. Which
2019年7月18日 · Doug C. Hi Mark H. By experimenting on Desmos with the graph of the circle and the graph of various lines where y = kx, along with the fact that the right triangle created by joining (3,1) with the points of intersection will have a hypotenuse = sqrt(10), I think k has a value very close to 1.1282.
Triangle ABC has vertices (0,0) ,(11,60) and (91,0). If the line y=kx ...
Triangle ABC has vertices (0,0) ,(11,60) and (91,0). If the line y=kx cute the triangle into two triangles of equal area then k= ?
some friends in college took a road trip to florida use the table to ...
2017年10月23日 · If the number "k" is the same for every pair in the table, you have a linear relationship, or you have a y=kx. If you figure out the "k" for one x-y pair, but it's different from the "k" for another x-y pair, that means your "rate" is not constant, that is, it varies and cannot be written in the form y=kx.
Find the values of k and b if it is known that the graph of y=kx+b …
Sai 9. asked • 10/17/17 Find the values of k and b if it is known that the graph of y=kx+b goes through points (2, 10) and (−7, −10)
A) If y=x^2+kx+3, determine the value (s) of k for which the
2015年3月6日 · k must be any even integer. Method: Find an expression, in terms of k, for the minimum value of the function and determine what sorts of k will yield an integer value. Because this question is asked in "Algebra", I will not use calculus, (Which is not needed to answer.) I will assume that you know that the minimum value of a quadratic function occurs at the vertex of …
If x is k percent of y, what percent of y is kx? - Socratic
2017年7月5日 · D) k^2% x is k% of y -> x=k/100*y :. kx = k(k/100*y) = k^2/100 *y = k^2% of y. What are the units used for the ideal gas law?
If y=kx, where k is a constant, and y=24 when x=6, what is
2018年7月26日 · You're right Solving for k, y = kx 24 = k(6) k = 4 Substitute in k and given x, y = 4x = 4(5) = 20 Option A: -6(5) - 5 = -35 Option B: 6(5) + 5 = 35 Option C: 6(5) - 5 = 25 Option D: 6(5)^2 - 15(5) = 75 None of the options is equal to 20 when x = 5.
