Weegy: 3x - 5x + 8x + x = 42

-2x + 9x = 42

7x = 42

x = 6

User: What is the slope of a line that is perpendicular to the line whose equation is 2y = 3x - 1? -3 -1/3 -2/3

Weegy: The answer is B=3/2. To find the slope of this line, first rearrange the equation to slope intercept form which is y=mx+b where m is the slope. [ After rearranging it, we get 2y=3x- 4.......divide by 2 to get y by itself......which in turn leaves us with y=1.5x- 2........therefore the slope is 1.5, or 3/2. ]

The common difference of the sequence 1/2, 1/4, 0, ... is: -1/4.
1/4 - 1/2 = 1/4 - 2/4 = - 1/4
0 - 1/4 = - 1/4

What is the slope of the line that is perpendicular to the line whose equation is 2x + y = 4. -2 -1/2
Weegy: To find a slope in a easy way is to find to points in the line. So plugging in values will help. Plugging in x=1 yields value of y=2(1)+5 = 7, and then next plugging 2 as x, we get y= 2(2)+5=9; so we get two points (1,7) and (2,9) in the line. The formula to find out the slope is - m=(y2-y1)/(x2-x1), again plugging in just found values we get m=9-7/2-1=2/1=2 now things to remember when calculating slop of a line perpendicular to any line is that it has a negative slope regard to the given line, and one more thing is that value also become reciprocal. So in that case it will be = -1/2 User: What is the equation of the line described below written in slope-intercept form? the line passing through point (4, -1) and perpendicular to the line whose equation is 2x - y - 7 = 0 y = -1/2x + 1 y = 1/2x - 1 y = 2x + 1 User: What is the equation of the line described below written in slope-intercept form? the line passing through point (0, 0) and parallel to the line whose equation is 3x + 2y - 6 = 0 y = -2/3x y = -3/2x y = 3/2x Weegy: The equation of the line passing through point (0, 0) and parallel to the line whose equation is 3x + 2y - 6 = 0 in slope intercept form is y = (-3/2)x (More)

The slope of the line that is perpendicular to the line whose equation is 2x + y = 4 is 1/2.
2x + y = 4
y = -2x + 4 so the slope of the line is -2.
The slope of its perpendicular line should be 1/2 since -2 * (1/2) = -1
