Answer:
B. x ≥ 3 or x ≤ −2
Step-by-step explanation:
<u>Inequalities</u>
Solve the inequality:
Subtracting 6:
Factoring:
(x-3)(x+2) ≥ 0
We have a product that must be greater or equal to 0. This can only happen if:
x - 3 ≥ 0 and x + 2 ≥ 0
Or:
x - 3 ≤ 0 and x + 2 ≤ 0
The first couple of conditions yields to:
x ≥ 3 and x ≥ -2
Which lead to the solution
x ≥ 3 [1]
The second couple of conditions yields to:
x ≤ 3 and x ≤ -2
Which lead to the solution
x ≤ -2 [2]
The final solution is [1] or [2]:
Answer:
B. x ≥ 3 or x ≤ −2
Answer:
(
+4)-3
Step-by-step explanation:
since it says "and four" i think it means it is in parenthesis
Find a counter example?
hmm
|a-b| finds the distance between a and b,
|a|-|b| finds the distance between a and b, such that |a|>|b|
ah ha
so we just need to find a and b such that b>a
b=10
a=5
|a-b|=|5-10|=|-5|=5
|a|-|b|=|5|-|10|=5-10=-5
5≠-5
tada
it is not true for all real numbers
if for all numers such that b>a, it is false
Keeping in mind that 70% of anything is 70/100 * anything, thus
so, you get that many percentage points, now... add that to 51.32.
