Sure yes.
1) x > - 3 or x < 3 means that the solution set is all the numbers greater than - 3 and all the numbers smaller than 3. That is, this union of intervals: (-3,∞) U (-∞,3), which is all the real numbers.
2) x > -3 and x <3 means that the solution set is the numbers that are at the same time greater than -3 and smaller than 3. That is the intersection of the intervals: (-3,∞) ∩ (-∞,3), which is the interval (-3, 3).
Answer:
b = -23.5
Step-by-step explanation:
4.7(3x - 5) = 14.1x - 23.5
Answer:
2 
pizzas
Step-by-step explanation:
The equation to this question can be written as 5/6 + 5/6 + 5/6 or 5/6 x 3.
To multiply 5/6 by 3, we can set it up as 
. Now to multiple, we just multiply straight across. We do 5 * 3 over 6 * 1 to get 15/6. Now, all we have to do is simplify the fraction. 6 goes into 15 two times, so we know they ate 2 pizzas. Now we are left with 3/6. 3/6 can be rewritten as . In total, they ate 2 pizzas.
Hope this helps!
Hi Mitsu there is no fraction to this. You multiply the base and height to get the area. So 512 x 512 = 262144
