Which expression could represent the phrase shown? (1 point)
ivolga24 [154]

Answer:

(6 - 2) / 3

Step-by-step explanation:

First, use parenthesis to declare that whatever is inside will be done first. This is saying to subtract 2 from 6. Next, add / 3 after to show you are dividing the answer of 6-2 by 3.

The center of a circle is located at (3, 8), and the circle has a radius that is 5 units long. What is the general form of the e
lana [24]
First we write equation that consist  coordinates of center and radius. That formula goes like this:
(x-x1)^2 + (y-y1)^2  = r^2

x and y are coordinates on any point on circle
x1 and y1 are coordinates of center of circle.
r is radius of that circle. now we need to express our values for center and radius andf square binoms and see what matches in our options.

(x-3)^2 + (y-8)^2 = 5^2
x^2 + y^2 -6x -16y +48 = 0

The answer is first option.

2. For f(x) = 2(x+3) - 5, name the type of function and describe each of the
Alexxandr [17]

Answer:

The function is a linear function

The function is translated 3 units to the left,then stretched vertically

by factor 2, then translated 5 units down

Step-by-step explanation:

* Lets revise some transformation

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

- If the function f(x) stretched vertically, then g(x) = k · f(x), where

 k > 1 (multiplying each of its y-coordinates by k)

- If the function f(x) compressed vertically, then g(x) = k · f(x), where

 0 < k < 1 (multiplying each of its y-coordinates by k)

* Now lets solve the problem

∵ f(x) = 2(x + 3) - 5

- The greatest power of the function is 1 (degree of the function)

∴ f(x) is linear function

- The parent function f(x) = x

∵ f(x) changed to f(x + 3)

∴ f(x) translated 3 units to the left

# Each x-coordinate of the points on the function subtracted by 3

∵ f(x + 3) changed to 2f(x + 3)

∵ 2 > 1

∴ f(x + 3) stretched vertically by factor 2 (k = 2)

# Each y-coordinate of the points on the function multiplied by 2

∵ 2f(x + 3) changed to 2f(x + 3) - 5

∴ 2f(x + 3) translated 5 units down

# Each y-coordinate of the points on the function subtracted by 5
