The pair of points (6, y) and (10, –1) lie on a line with slope one quarter. what is the value of y? (1 point)a. –5

1 answer:

5 0

The slope of this connecting line segment is
-1 - y 1 -(1+y)
m = ---------- = ----- = --------
10-6 4 4

Thus, 4 = -4(1+y), or 4 = -4 - 4y, or -8 = - 4y. y = 2 (answer)

X+4/x-1 divided by x^2 +x/x-1<br> 3/2x-1 subtract by 5/2x-1 <br> how do you do them

ElenaW [278]

$\frac{x + 4}{x - 1} / \frac{x^{2} + x}{x - 1} = \frac{x + 4}{x - 1} * \frac{x^{2} + x}{x - 1} = \frac{(x + 4)(x^{2} + x)}{(x - 1)(x - 1)} = \frac{x^{3} + x^{2} + 4x^{2} + 4x}{x^{2} - x - x + 1} = \frac{x^{3} + 5x^{2} + 4x}{x^{2} - 2x + 1} = x + 7 + \frac{17x - 7}{x^{2} - 2x + 1}$

$\frac{3}{2x - 1} - \frac{5}{2x - 1} = -\frac{2}{2x - 1}$
