Answer:
Step-by-step explanation:
Let the speed of current be x
<u>Speed of the boat in same direction as current is</u>
<u>Speed against the current is</u>
<u>Based on the given we get the equation for time</u>
<u>Solving for x</u>
- 6(10 - x) = 4(10 + x)
- 60 - 6x = 40 + 4x
- 6x + 4x = 60 - 40
- 10x = 20
- x = 2
The answer is 2 mph
The given proportional relationship is y = -5x.
Therefore the ratio
y/x = -5 = -5/1
If x changes by 1, then y/x = y/1 = -5.
This means that y changes by -5 when x changes by 1.
The ratio of vertical change is -5:1
The standard equation for a straight line is
y = m*x + c
where
m = the slope,
c = the y-intercept.
Therefore the given relationship is a straight line with a negative slope of -5. This means that y decreases as x increases.
Answer: C
-5:1
The graph decreases from left to right.

Answer:
$522.60
Step-by-step explanation:
pencils: $4.10 * 6 ===> $24.60
pens: $6.50 * 12 ===> $78
notebook paper: $105 * 4 ===> $420
pencils + pens + notebook paper = total cost
24.60 + 78 + 420 = 522.60
