Answer:

a - Original length = 18; b - Original length = 12; c - Copy length = 15, ratio = 2/3

Step-by-step explanation:

For part a, we know the ratio is 2/3. We also know the copy length is 27.

To change the denominator of the ratio to 27, we would multiply by 9; multiplying the top by 9, we have 2(9) = 18.

For part b, we know the ratio is 2/3. We also know the copy length is 18.

To change the denominator of the ratio to 18, we would multiply by 6; multiplying the top by 6, we have 2(6) = 12.

For part c, we only have one option left for the copy length; it must be 15.

This makes the ratio 10/15, which simplifies to 2/3.

A- Original length = 18
b- Original length = 12
c- Copy length = 15 ; Original Length/Copy Length = 2/3

Answer:

Step-by-step explanation:

Fill in the given values and do the arithmetic.

$\dfrac{12x-3y}{4x-z}=\dfrac{12\cdot3-3\left(\dfrac{1}{3}\right)}{4\cdot3-5}=\dfrac{36-1}{12-5}=\dfrac{35}{7}=\boxed{5}$

Answer:

$\textbf{D.}\quad g(x)=\sqrt{x+6}+4$

Step-by-step explanation:

A lot of math is about matching patterns.

For example, ...

g(x) = f(x -h) +k

means g(x) is the function f(x) translated right by h units and up by k units. This will be true for any expression of f(x).

In this problem, f(x) = √x. We want to translate it left 6 units (h=-6)*, and up 4 units (k=4).

The notation above means that we will replace x with (x-h) = x+6. and we will add k = 4 to the result.

f(x) = √x

g(x) = f(x+6) +4

g(x) = √(x+6) +4 . . . . . . matches choice D

_____

* Left is the opposite of right, so left 6 units is the opposite of right 6 units. h=6 for right 6 units, so h=-6 for left 6 units. Then x-h = x-(-6) = x+6.

Comment on the graph

I find it useful to see a picture with these things. In the attached graphing calculator output, the blue curve is left 6 and up 4 from the red curve. The blue curve is g(x); the red one is f(x).
