Answer:
C. X = 1/2
Step-by-step explanation:
4x - 3 + 5 = 2x + 7 - 8x
4x +2 = - 6x + 7
4x + 6x = 7 - 2
10x = 5
x = 1/2

Answer:
i cannot tell where the seperate numbers are and where the x is multiplication and what numbers are negative. post it agian but put spaces in beetween.
Step-by-step explanation:
remember:
PEMDAS
P- parenthases
E- exponents
M- multiplication
D- division
A- addition
S- subtraction
note:
M, D are tied so do it left to right
A, S are tied so do them left to right
-1r. A positive smaller than another positive being subracted by a positive
is a negative
Answer:
Step-by-step explanation:
We will solve this questions using some dimensionality analysis.
a) Note that 
is a vector space of dimension 4. So, given a set of three vectors, they could be or could not be linearly independent. However, if they were, they would not span since in order for us to span we need 4 or more vectors. Since a set of three vector cannot span this space, they automatically cant be a basis for .
b) 
has a dimension 3. So, for a set of vectors A to span this space, we need that A contains at least 3 vectors that are linearly independent. So A could have possibly infinite number of vectors as long as there is a subset of A that is composed by 3 linearly independent vectors.
