Find (x,y) such that (8,2)(x,y) = (28,22)

Mathematics
1 answer:
liberstina [14]3 years ago

Answer:

(x,y) = (3.5, 11)

Step-by-step explanation:

(8,2)(x,y) = (28,22)

Dot product, so:

(8,2)(x,y) = (8x,2y) = (28,22)

Then

8x = 28

x = \frac{28}{8} = 3.5

And

2y = 22

y = \frac{22}{2} = 11

So

(x,y) = (3.5, 11)
