Answer:
3) 5/2
Step-by-step explanation:
5x - 2y = 20
(First, put it in slope intercept form: y = mx + b).
5x - 2y - 5x = 20 - 5x --> Subtracted 5x on both sides of the equation
- 2y = -5x + 20 --> Simplified
-2y/-2 = (-5x + 20)/-2 --> Divided by -2 on both sides
y = 2.5x - 10 --> Simplified
Since formula is, y = mx + b, then:
m (slope): 2.5
b (y-intercept): -10
Therefore, the answer is 3) 5/2

This seems like a personal question
Answer:
Step-by-step explanation:
a) increase
Increase = 200 -130 = 70
Percent increase = (70/130)*100 = 70*100/130 = 7*100/13
= 700/13
= 53.85%
In ijk notation, the boat has velocity (relative to the water)
and the current has velocity (relative to the Earth)
The boat's "true" velocity (relative to the Earth) satisfies
so that
which translates to a speed of about 16.5 km/hr in a direction of 25.48º South of East.
