Answer:
5x-1
Step-by-step explanation:
8x-3(x+1)-4
{open the brackets}3x-3
8x-3x-3-4
5x+(-7), which is 5x-7
Answer:
The slope is 2
Step-by-step explanation:
So convert the equation into point slope form
y=mx+b
Isolate the 2y by adding 4x to both sides using inverse operations
2y=-16+4x
now divide 2 on both sides to make y isolated
y=-8+2x
Now convert
y=2x-8
the slope is 2
Consider this option:
1) if the angle belongs to IV quadrant, it means cos is in [0;1];
2)
using this formula cosθ=√(5/9) ⇒ cosθ=√5/3
