-9= 2x-5
Add 5 to both sides
-4= 2x
Divide by 2
-2=x or x=-2
<h3>
Answer: Perpendicular</h3>
The slopes -2/3 and 3/2 multiply to -1, which is sufficient info that the lines are perpendicular. Perpendicular slopes always multiply to -1 assuming neither line is vertical nor horizontal.
Note how -2/3 is the negative reciprocal of 3/2, and vice versa.
Answer:
- 1/12
Step-by-step explanation:
Let -0.0833333 = x --- (1)
Multiply both sides by 10.
-0.833333 = 10x --- (2)
Subtract (2) from (1),
0.75 = -9x
-9x = 
= 


Answer:5
Step-by-step explanation:
Step-by-step explanation:
One pound = $0.65
Total cost = c
Number of pounds to ship = p
Part a:
c = 0.65p
When p = 2
c= 0.65(2)
c = $1.30
Part b:
One pound = $0.65 - $0.05 = $0.60
c= 0.6p
Answer: (a) $1.30 (b) c= 0.6p
