The Reagan school marching band has three percussion musicians. How many musicians altogether in band ? 1/3 wood winds 1/6 percu
Artyom0805 [142]
1/6 percussion 
1/3 wood winds = 2/6 (which is twice as many as percussion) 
1/2 brass = 3/6 (which is three times as many as percussion)

So percussion = 3
wood winds = 6
brass = 9
all together = 3 + 6 + 9 = 18

From the figure, the vertices of the given triangle are
(-3,4), (1,3) and (5,5).

The given transformation is (x,y) -> (x+3, y-2).
Therefore the coordinates of the transformed triangle are
(-3+3,4-2), (1+3,3-2), (5+3,5-2) = (0,2), (4,1), (8,3)

The transformed triangle is shown in red color.

The table below shows a pattern in the cost of renting a car based on the number of days rented. Car Rentals Number of Days (d)
andrezito [222]

The linear equation that describes the pattern in the cost of renting a car is given by:

  • D. c = 34d + 25

<h3>What is a linear function? </h3>

A linear function is modeled by:

y(x) = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

In this problem:

  • For each day, the cost of renting a car increases by 34, hence, the slope is of 34, and the equation is:

c(d) = 34d + b

When d = 4, c = 161, and this is used to find b.

c(d) = 34d + b

161 = 34(4) + b

b = 25

Hence, the equation is c = 34d + 25, and option D is correct.
