HI i know i am a week late but i hope this helps in some way. :)
X = Mateo Trading cards
4x-7 = Camila Treading cards
(4x-7) +x>51
4x-7+x>51
5x-7>51
5x>51+7
5x>58
x>58/5
x>11.6 = 12
Mateo can have at least 12 trading cards
Facts:
- tub has 1400 gallons
- draining at 27 gallons/minute
How much water will be left after 18 minutes?
We know that after 1 minute, there will be 27 gallons less.
So after 18 minutes, there must be 18 times less water.
27 x 18 = 486
This is how much water was lost in 18 min
So to find out how much he had left after <u>486 is subtracted.</u>
Therefore, the answer is A) -486 gallons
Answer:
A is spanned by vector.
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
