X-the number
20 · x² = 20 · x |divide both sides by 20
x² = x |subtract x from both sides
x² - x = 0
x(x - 1) = 0 ⇔ x =0 or x - 1 = 0
Answer: x = 0 or x = 1
Answer:
2x2 matrix
Step-by-step explanation:
Given
Dimension of matrices A = 2x2 matrix
Dimension of matrices B = 2x1 matrix
The dimension of matrix AB can be gotten by cancelling the row of matrices 1 and column of matrices 2.
After cancelling both row and column, the remaining dimension will be 2x2 matrix. Hence the dimension of AB is 2x2 matrix
At 8 hours of service, the two limousine rental companies charge the same amount.
Step-by-step explanation:
Given,
Initial fee of Executive Limousine rental = $200
Per hour charges of service = $40
Let,
x be the number of hours.
E(x) = 40x+200
Initial fee of Jet Limousine rental = $120
Per hour charges of service = $50
J(x) = 50x + 120
For the charges to be same;
E(x) = J(x)

Dividing both sides by 10

At 8 hours of service, the two limousine rental companies charge the same amount.
