Let u=  (-1,3) and w =(2,4) Find the resulting vector of 2u-4w  in component form..
IgorLugansk [536]
Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this: 

2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)

(4,8) - (-4,12) = (8,-4)

So the vector has the coordinates (8,-4)

a wooden fruit crate will hold 62 pounds of fruit. the crate already has 18 pounds of fruit in it. which inequality represents t
tatuchka [14]

Answer:

p + 18 \leq 62

Step-by-step explanation:

Given

Total = 62\ lb

Current = 18\ lb

Required

Write an inequality to represent the scenario?

Represent the additional number of pounds with p.

When p is added to the current pounds, the weight must be less than or equal to the total possible weights

In other words:

p + current \leq total

Substitute values for current and total

p + 18 \leq 62

Hence, the inequality that describes the scenario is: p + 18 \leq 62
