Answer:
The answers are below
Step-by-step explanation:
The greater sign is > and the less then symbol is <
Using the red arrows on the number line, you can tell which one is bigger or less. The dot is colored in so it has to have a line under it. So for the first one (top, left), The red arrow is pointing to the right side meaning x is bigger than 3. Therefore x ≥ 3.
In the next one (top, right) the arrow is pointing to the negative side so that one must be less than 3. The dot is also colored in meaning it is: x ≤ 3
In the next one (bottom, left) the arrow is pointing to the right, the dot not colored in, so it has no line. Therefore it is x > 3
Last one (bottom right) the arrow is pointing left, dot is white meaning that the answer is x < 3
If you're wondering what the open dots and closed dots mean:
An open dot is used to show that the ray's endpoint is not a component of the solution when the inequality is "strict" ( < or >).
A closed dot is used to denote that the endpoint is a component of the solution for the other types of inequalities (≥ and ≤ ).
Answer:
C
Step-by-step explanation:
5ax²-20x³+2a-8x
=5 x²(a-4x)+2(a-4x)
=(a-4x)(5x²+2)
Answer:
1,792 -7168
the pattern is to multiply by -4
Step-by-step explanation:
7 · -4 = -28
-28 · -4 = 112
112 · -4 = -448
-448 · -4 = 1,792
1,792 · -4 = -7168
Answer:
The question continues ; I take it is defined as a set of five white and one red number how many possible different Powerball tickets can be purchased how many possible different winning Powerball tickets are there
Step-by-step explanation:
he concept of combinatorics ( combination and permutation) is applied her
nPr = n!/(n-r)!
nCr = n!/(n-r)!r!
Hence number of possible different powerball tickets = number of ways of selection
= selecting 5 white ball from a total of 69 and selecting a red ball from a total of 26
= 69C5 x 26C1
using the formula above for combination
= 69!/(69-5)!5! x 26!/(26-1)!1!
= 292, 201, 338 ways
Answer: Nope.
Step-by-step explanation: All circles are round and have no corners. Therefore, they cannot have any angles - right angles included.
