Answer:
3 (8v+5) (8v-5)
Step-by-step explanation:
192v^2 -75
factor out a 3
3 (64v^2 -25)
now the inside is a difference of squares)
a^2 – b^2 = (a + b)(a – b) where a = 8v and b =5
3 (8v+5) (8v-5)
Answer: -1, 0, 1, 2, 3
Step-by-step explanation:
If we say the expression out loud, we say it as "m is greater than -2 but less than or equal to 3."
This is because < or > means less than or greater than. These don't include the given value.
≤ or ≥ means less than or equal to or greater than or equal to. These do include the given value/values.
In this equation, we don't include -2, but we include 3. That's why the included values are -1, 0, 1, 2, 3.
The easiest way to do this is by graphing the equation. I'll do it:
We see that the y intercept is 11.
Formula for slope-intercept: y = mx + b
mx = slope
b = y-intercept
Now we have y = mx + 11. What's mx? We can find that out from the graph.
Let's find two points: (0,11) (4,3)
Using <span> (y2 - y1)/x2 - x1): We see that the slope is -2.
Now we finish the slope-intercept form and plug it all in:
y = -2x + 11
