The answer is f(x) = (x/4) - 3
4/4=1-3=-2
You haven't given us the vector, and there an infinite number of planes through the two points.
Answer:
C
Step-by-step explanation:
The best way to solve this is to transfer -217 to the other side. So add 217 to both sides
0 ≤ 7 + 217 - 28v Combine
0 ≤ 224 - 28v Now add 28v to both sides
28v ≤ 224 Divide by 28
28v/28≤224/28
v ≤ 8
You should have 2 questions on your mind.
- Why go to all the trouble of putting things on the opposite sides?
- What is the answer
1. You so all that trouble so that you don't have to switch the < to >. As long as you have the letter and its coefficient > 0, then you are going to be right.
2. The is v is less than or equal to 8. That's C
1. In this problem, the variable x represents how many pounds of hamburger meat you're buying. So, to solve the expression, just replace x with how much you're buying, in this case, 7.
2.50x Plug in 7 pounds for x
2.50(7) Multiply
17.50
You will pay $17.50 for 7 pounds of hamburger meat.
2. 8 times (8 x) the product (multiplication) of g and h.
The product of g and h means you multiply them, so it will be gh. Then, you'll multiply that by 8 and get 8gh. So, the correct answer is choice B.
