(70x10)+(6x1)+(4x1/10)+(2x1/100)+(9x1/1000)
Answer:
Step-by-step explanation:
Take out 3x from both sides:
5x - 3x = 3x - 3x
2x = 0
2x + 9 = 1
Take out 9 from both sides:
9 - 9 = 1 - 9
0 = -8
Divide 2 from both sides:

Answer:
It's the last choice:
2x + y - 1 = 0.
Step-by-step explanation:
x - 2y - 3 = 0
Convert to slope-intercept form in order to find the slope:
-2y = -x + 3
y = 1/2x - 3/2
So the slope is 1/2. The slope of a line perpendicular to this is -1 / 1/2 = -2.
Using the point-slope form to find the required equation:
y - y1 = m(x - x1)
x = 4 and y = -7 so we have:
y + 7 = -2(x - 4)
y + 7 = -2x + 8
2x + y - 1 = 0 is the answer.
