U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
Answer:
-2x + 6
Step-by-step explanation:
Step 1: Write expression
3(x + 2) - 5x
Step 2: Distribute
3x + 6 - 5x
Step 3: Combine like terms
-2x + 6
Answer:
y = -2x + 1
Step-by-step explanation:
So, first you can use rise over run between the two points to find the slope.
This will get you -6/3, which you can simplify to -2
Then, see where the y intercept is, which is at (0, 1)
The equation will be y = -2x + 1
Answer: no.
