9 is your answer. When you have a negative squared number, your answer will be positive. Think of it like -3*-3.
-4 x = -4 -16 = 4x = -20
divide both sides of the equation by -4
-The answer to your question is 5, or x = 5! Hope this helps
Answer:
E is not a subspace of
Step-by-step explanation:
E is not a subspace of
In order to see this, we must find two points (a,b), (c,d) in E such that (a,b) + (c,d) is not in E.
Consider
(a,b) = (1,1)
(c,d) = (-1,-1)
It is easy to see that both (a,b) and (c,d) are in E since 1*1>0 and (1-)*(-1)>0.
But (a,b) + (c,d) = (1-1, 1-1) = (0,0)
and (0,0) is not in E.
By the way, it can be proved that in any vector space all sub spaces must have the vector zero.
Hello!
Let's do this step by step!
We must convert 24/40 to a decimal before we can find out what percentage of 40 is 24.
To convert 24/40 to a decimal, we must multiply the numerator (24) by the denominator (40):
24 ÷ 40 = 0.6
Now that we have the decimal form, we will multiply the decimal by 100 to convert it to a percentage.
0.6 × 100 = 60
24/40 = 60%
