2 divided by 18 is 9 and 3 divided by 18 is 6 hope that helps
Answer:
x+3≤20
x≤17
Step-by-step explanation:
let the amount of money left for misc expenditures = x
Number of pencils bought = 6
cost of each pencil = $0.50
Total expense on pencil = 6 x $0.50 = $3
Total expenditure =x+3
Maximum expenses allowed = $20
Hence
Total expenditure must be less than or equal to $20
Hence
x+3≤20
Subtracting 3 from both sides
x≤17

Answer:
x = <1,5>
y = <-5,1>
Step-by-step explanation:
Let x, y be two vectors in 2D
defined as:
x = <a, b>
y = <c, d>
for x, y to be orthogonal, we know that their dot or scalar product must be zero so,
x . y = 0
<a, b> . <c, d> = 0
a*c + b*d = 0 ------ (A)
Now, consider any four values for a, b, c, and d respectively which satisfy the equation (A)
i.e. I chose (you can choose on your own choice):
a=1, b=5, c=-5, d=1
Verifying Equation (A):
(1)*(5) + (-5)*(1) =0
5 - 5 = 0
0 = 0 (True)
Therefore,
Our vectors x, y are:
x = <1, 5>
y = <-5, 1>
