Solve -2x + 6 = -20. -13 13 -7 7
alexdok [17]

Note the equal sign. What you do to one side, you do to the other.

Also, remember to do the opposite of PEMDAS.

First, subtract 6 from both sides

-2x + 6 (-6) = -20 (-6)

-2x = -26

Next, isolate the x. Divide -2 from both sides

(-2x)/-2 = (-26)/-2

x = -26/-2

x = 13

13, or (B) is your answer

Check the true statements below:
valentinak56 [21]

Answer:

a) False

b) False

c) True

d) False

e) False

Step-by-step explanation:

a. A single vector by itself is linearly dependent. False

If v = 0 then the only scalar c such that cv = 0 is c = 0. Hence, 1vl is linearly independent. A set consisting of a single vector v is linearly dependent if and only if v = 0. Therefore, only a single zero vector is linearly dependent, while any set consisting of a single nonzero vector is linearly independent.

b. If H= Span{b1,....bp}, then {b1,...bp} is a basis for H. False

A sets forms a basis for vector space, only if it is linearly independent and spans the space. The fact that it is a spanning set alone is not sufficient enough to form a basis.

c. The columns of an invertible n × n matrix form a basis for Rⁿ. True

If a matrix is invertible, then its columns are linearly independent and every row has a pivot element. The columns, can therefore, form a basis for Rⁿ.

d.  In some cases, the linear dependence relations among the columns of a matrix can be affected by certain elementary row operations on the matrix. False

Row operations can not affect linear dependence among the columns of a matrix.

e. A basis is a spanning set that is as large as possible. False

A basis is not a large spanning set. A basis is the smallest spanning set.

Answer key says 50, but i have no idea how to get it. can anyone please help me?
Lady_Fox [76]

Answer:

x=50

Step-by-step explanation:

note that 40% is 2/5

Therefore, 30 tomatoes is 1- 2/5 = 3/5

3/5 of the tomatoes last year is 30

lets say tomatoes = x

3/5 x = 30

divide by 3 on both sides

1/5 x = 10

multiply by 5 on both sides

x=50

:D

hope it helped :D
