At the halftime show, a marching band marched in formation. The lead drummer started at a point with coordinates ( − 2 , − 5 ) ( - 2 , - 5 ) and moved 3 steps up and 1 step right. Write a rule to describe the translation. What were the coordinates of the drummer's final position?

a) The answer is: (x + a, y + b)

b) The answer is: (-1, -2)

The initial coordinates are:

(x, y) = (-2, -5)

Find a and b.

a is a distance in x direction: a = 1

b is a distance in y direction: b = 3

The final position is:

(x + a, y + b) = (-2 + 1, -5 + 3) = (-1, -2)

Answer:

(-1, -2)

vivado [14]

Answer:

y - intercept = 2.25

Step-by-step explanation:

y = mx + c

Where,

y = Total cost

x = additional cost

m = slope

c = y - intercept

y = 0.25x + 2.25

Relating with the above equation,

y - intercept = 2.25

Slope, m = 0.25

How can the average rate of change be identified for a function?

Digiron [165]

Answer:

$Rateofchange=\frac{f(x_2)-f(x_1)}{x_2-x_1}$

where x₁ and x₂ are values in the interval [x,y] respectively

Step-by-step explanation:

Well, first to determine the average rate of change of a function, you should have the interval of the values of x for the function.

So lets assume you have a function;

$f(x)=x^3-4x$

And the interval as [1,3]

Then the average rate of change for the function f(x) will be;

$=\frac{f(x_2)-f(x_1)}{x_2-x_1}$

where x₁ and x₂ are the interval coordinates x,y respectively. In this case x₁=1 and x₂=3

To find the average rate of change in this example will be;

$=\frac{f(x_2)-f(x_1)}{x_2-x_1} \\\\=f(x_2)=f(3)=3^3-4(3)=27-12=15\\\\=f(x_1)=f(1)=1^3-4(1)=1-4=-3\\\\\\=x_2-x_1=3-1=2\\\\\\=\frac{15--3}{2} \\\\=\frac{18}{2} =9$
