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.
Two intersecting lines will form 2 pairs of congruent vertical angles. Congruent angles have the same angle measure; vertical angles are opposite angles formed by 2 intersecting lines.
Answer:
The answer is "
".
Step-by-step explanation:
In the question the total given value =4(x+7). if we add the value it will be 11 but if we multiply the value it is equal to .
Answer:
x = 2
Step-by-step explanation:
Using Pythagoras identity in the right triangle
x² = 10² + 6² = 100 + 36 = 136 ( take the square root of both sides )
x = 
= 
= 2
