Answer:
A. 7.50 per box
Step-by-step explanation:
We know that when there are 4 boxes, we make 30 dollars. Divide 4 from 30 to get 30/4 which is equal to 7.5. This means we make 7.5 dollars per box.

We have the same base, which in this case is x.
When multiplication occurs in the same base, we add the powers

↓ (I am going to perform the problem separately and then give the final answer as the power to x)

=

↓
x²

The power of a power should be performed by multiplying the powers together.
2 x

=


Your final answer will be the second option
Answer:
Your right the answer is 74
Step-by-step explanation:
Answer:
1) a. False, adding a multiple of one column to another does not change the value of the determinant.
2) d. True, column-equivalent matrices are matrices that can be obtained from each other by performing elementary column operations on the other.
Step-by-step explanation:
1) If the multiple of one column of a matrix A is added to another to form matrix B then we get: |A| = |B|. Here, the value of the determinant does not change. The correct option is A
a. False, adding a multiple of one column to another does not change the value of the determinant.
2) Two matrices can be column-equivalent when one matrix is changed to the other using a sequence of elementary column operations. Correc option is d.
d. True, column-equivalent matrices are matrices that can be obtained from each other by performing elementary column operations on the other.
Answer:
All real numbers greater than or equal to -3
Step-by-step explanation:
First look at graph where the line points to which direction of the graph
And look for any closed or open circles in the graph
Since in the graph has a close circle at (-3,-2) meaning it includes that x-value for its domain.
With the graph going to positive infinity it states that the domain is all real numbers.
So in conclusion it has a domain of all real numbers greater than or equal to -3
