\huge \sf༆ Answer ༄

Let's solve ~

  • \sf {x}^{2}  - 10xy + 21 {y}^{2}

  • \sf {x}^{2}  - 7xy - 3xy + 21 {y}^{2}

  • \sf x(x - 7y) - 3y(x - 7y)

  • \sf( x - 7y)(x - 3y)

Hence, the correct choice is ~ A

What is the y-intercept of the line perpendicular to the line y = four thirdsx + 1 that includes the point (4, 1)?
s2008m [1.1K]

Answer:

(C)4

Step-by-step explanation:

Given the line: y=\dfrac43 x+1

The gradient of the line, m=\dfrac43

A line perpendicular to the given line will have a gradient, m=-\dfrac34 (by definition of perpendicularity).

Therefore, a perpendicular line that passes through the point (4,1) is:

y-y_1=m(x-x_1)\\y-1=-\dfrac34(x-4)\\y-1=-\dfrac34x+3\\y=-\dfrac34x+3+1\\y=-\dfrac34x+4

Comparing with the slope-intercept form y=mx+x, the slope of the perpendicular line, b=4.
