This equation is an example of the distributive property. You multiply what is on the outside of the parentheses by what is inside. This would give us 6x+15-x. I believe that the previous answer given was incorrect. This is an example of the distributive property.

1OO POINTS PLEASE HELP
kondor19780726 [428]

2) Period = 3π,

2π/b = 3π, b = 2π/3π = 2/3

Amplitude = 2

Midline = 1

Equation: f(x) = 3sin(2/3(x)) + 1 (no vertical shift)

See attachment for graph.

3) f(x) = -23sin(4x) + 14,

a) amplitude = 23

b) midline = 14

c) Maximum = 37

d) Minimum = -9

Does the system of equations have no solution, one solution, or an infinite number of solutions? −5x+y=−1−5x+y=10
kherson [118]

Answer:

<em>5x-y=9, y=5x+19 write both equations in same formy=5x-9 for the first and havey=5x+19 for the second. These are two parallel lines with different intercepts. They do not intersect or coincide. No </em><em>solutions</em>

<em> </em>

<em>and y=6x+14, 12x-2y=-28 write both equations in same formy=6x+142y=12x+28 or y=6x+14. They are the same line. The solution is all of the points on the line.</em>

Step-by-step explanation:

David canoes 20km downstream in 2.5 hours his return trip takes 4 hours find the rate of his current. A 1.5 km/h B 1 km/h C 0.5
Art [367]

Answer:

1.5 km/hour

Step-by-step explanation:

d is the David's speed in still water

c is the speed of the current

Going with the current, he travels d+c km per hour.

Going against the current, he travels d-c km per hour.

d+c = (20 km)/(2.5 hours) = 8 km/hour

d-c = (20 km)/(4 hours) = 5 km/hour

Add the equations to eliminate the c terms

d+c = 8

d-c = 5

----------

2d = 13

d = 6.5 km/hour

c = 8-d = 1.5 km/hour
