Step-by-step explanation:
16x^2 - 4
4(4x²-1)
4((2x)²-1²)
4(2x+1)(2x-1)
Answer:
-1>x
Step-by-step explanation:
-5x - 15 > 10 + 20x
Add 5x to each side
-5x+5x - 15 > 10 + 20x+5x
-15> 10+25x
Subtract 10 from each side
-10 - 15 > 10-10 + 25x
-25> 25x
Divide each side by 25
-25/25> 25x/25
-1>x
If you know what the equation of the line IS(y=mx+b), then you can:
Substitute the x coordinate, slope and y-intercept into the line, then solve for y.
Hope this helped!
Answer:
Slope is 5/4.
Step-by-step explanation:
The slope of two points can be expressed as
where m represents the slope,
Let (5,5) be (x1,y1) and (1,0) be (x2,y2). Thus:

You can also consider both points other way around. We can let (1,0) be (x1,y1) and (5,5) be (x2,y2) and therefore:

Therefore, the slope is 5/4.
