Answer:
True
Step-by-step explanation:
Let B={} a set of vectors containing the zero vector.
B is linear dependent if exist scalars not all zero such that .
Observe that if and then
.
Then B is linear dependent.
Answer:
<u>Please read the answers below.</u>
Step-by-step explanation:
A. Write an equation to represent each company's total charges for cleaning a certain number of loads of laundry.
Company A equation (using x as the variable for the total cost and y for the number of loads)
<u>x = 20y + 8</u>
Company B equation (using z as the variable for the total cost and y for the number of loads)
<u>z = 24y + 4</u>
B. Which company would charge less for 5 loads of laundry?
Company A
x = 20 * 5 + 8
<u>x = US$ 108</u>
Company B
z = 24 * 5 + 4
<u>z = US$ 124</u>
<u>Company A will charge US$ 108, US$ 16 less than Company B</u>
C, How much money is saved by using the services of Company A instead of Company B to clean 9 loads of laundry?
Company A
x = 20 * 9 + 8
<u>x = US$ 188</u>
Company B
z = 24 * 9 + 4
<u>z = US$ 220</u>
<u>Company A will charge US$ 188, US$ 32 less than Company B</u>
This is not hard to simplifi all you need to do is collect like terms because 3 and 2 are like terms we put them together making 3x - 5 because when you have 2 plus you make it into a minus. I hope this helped you.
