Answer:
-8
Step-by-step explanation:
Answer:
1/8
Step-by-step explanation:
<u>Solving in steps:</u>
- x(8x - 8y)⁻¹ + y(8y - 8x)⁻¹ =
- x/8(x-y) +y/8*(-(x-y))
- x/8(x-y) - y/8(x-y) =
- (x -y)/8(x-y) =
- 1/8
Answer is 1/8
Answer:
The answer is b
Step-by-step explanation:
(4x+5)(16^2-20x+25)
5x + y = -13.....multiply by -3
4x + 3y = -17
-----------------
-15x - 3y = 39 (result of multiplying by -3)
4x + 3y = -17
-----------------add
-11x = 22
x = -22/11
x = -2
5x + y = -13
5(-2) + y = -13
-10 + y = -13
y = -13 + 10
y = -3
solution (-2,-3)
Answer:
positive slope
(0,3)
slope = 2
Step-by-step explanation:
- Slope of the given line is positive
- If the line is sloping upward from left to right, so the slope is positive (+).
or if the angle made by the line to the x axis is < 90 it's slope is positive.
- y-intercept of the line is (0,3)
- The y intercept is the point where the line crosses the y axis. At this point x = 0.
- slope of the line is 2
- slope = (y2 - y1) / (x2 - x1)
lines passing through points (1,5) (0,3)
slope = (3 - 5) / (0 - 1)
= -2 / -1 = 2
