Parallel to the graph of y = -2/3x + 5
means that it has the same slope
Rewrite
y = -2/3x + b
plug in the given coordinates to solve for b
5 = -2/3(-3) + b
5 = 2 + b
subtract 2 from both sides
3 = b
plug that back into the equation
y = -2/3x + b
y = -2/3x + 3
The answer is <span>B. y= -2/3x+3</span>
This line is parallel to y = -2/3x + 5 and it passes the point (3, 5).
Hope this helps :)
[1] Amount of water per minute
Water Miser: m = 3.0 gal/min
Watersaver: m = 2.5 gal/min
Waterstream: m = 1.5 gal/min
[2] Equations:
I would suggest using y = mx.
Water Miser: y = 3x
Watersaver: y = 2.5x
Waterstream: y = 1.5x
[3] For 6,8,10, and 12 minutes:
Plug in x = 6, x = 8, x = 10, and x = 12 into each of the three equations and record the y-values.
[4] Which would you buy?
Depends on your personal opinion.
Want to save the earth? Pick the one that uses the least amount of water.
Want to have a waterfall for a shower? Pick the one that uses the most amount of water. :)
Answer:
3/4
Step-by-step explanation:
Cylinder A
V = πr^2h
V = π(3)^2(4)
V = 36π
Cylinder B
V = π(4)^2(3)
V = 48π
36π/48π
3/4
Answer:
x = 17
, y = 34
Step-by-step explanation:
Since the triangle is right use trig ratios to find x and y
note exact values sin30° = 
, tan30° = 
sin30° = 
= 
multiply both sides by y
y sin30° = 17 ( divide both sides by sin30° )
y = 
= 34
tan30° = 
= 
multiply both sides by x
x tan30° = 17 ( divide both sides by tan30° )
x = 
= 17
