the answer is A
if you multiply x by 3 then add 2 you get f(x)

<h3>
Answer: It is <u>
not</u>
a solution</h3>
======================================================
Explanation:
Plug in w = -2 and simplify.
3w ≤ -12
3(-2) ≤ -12
-6 ≤ -12
The last inequality is false because -6 is neither equal to -12, nor is -6 smaller than -12. Use a vertical number line to see that -6 is above -12, so it should be -12 ≤ -6.
Since -6 ≤ -12 is false, that makes 3w ≤ -12 false when w = -2.
Therefore, w = -2 is <u>not</u> a solution to the given inequality.
Answer:
(-1,-5)(0,-8)(1,-9)(2,-8)(3,-5)
Step-by-step explanation:
Answer:
E(X) = 0.64
Sd(X) = 0.933
Step-by-step explanation:
3(0.07) + 2(0.11) + 1(0.21)
E(X²) = 3²(0.07) + 2²(0.11) + 1²(0.21)
= 1.28
Var(X) = 1.28 - 0.64² = 0.8704
Sd = 0.933
