B. 5 is the input

Step-by-step explanation:

f(x) = 4x + 3        f(5) = 23             Plug in 5 for x.

f(x) = 4(5) + 3

f(x) = 20 + 3

f(x) = 23

Answer:

x>-1

Step-by-step explanation:

-2x +3 < 5

Subtract 3 from each side

-2x+3-3 < 5-3

-2x < 2

Divide each side by -2

Remember that flips the inequality

-2x/-2 > 2/-2

x>-1

Answer:

Starting average customer rating was 5.

Step-by-step explanation:

Equation representing the average customer rating at Austin's bakery over time is,

y = 0.25x + 5

Here, 'x' represents the time or duration.

Starting average customer rating means value of y at x = 0.

Therefore, y = 0.25(0) + 5

y = 5

Starting average customer rating was 5.

In the diagram below, we have $ST = 2TR$ and $PQ = SR = 20$. Find the length $UV$.
Maslowich

Answer:

12

Step-by-step explanation:

1. ST=2TR and SR=20, then by segment addition postulate

ST+TR=SR\\ \\2TR+TR=SR\\ \\3TR=20\\ \\TR=\dfrac{20}{3}\\ \\ST=2\cdot \dfrac{20}{3}=\dfrac{40}{3}

2. Consider triangles PQU and TSU. These triangles are similar by AA similarity theorem (triangles have congruent vertical angles PUQ and TUS and congruent alternate interior angles PQU and TSU). Similar triangles have proportional corresponding sides, so

\dfrac{QU}{US}=\dfrac{PQ}{ST}=\dfrac{20}{\frac{40}{3}}=\dfrac{60}{40}=1.5

QU=1.5US

3. Consider triangles QUV and QSR. These triangles are similar by AA similarity theorem. Similar triangles have proportional corresponding sides, so

\dfrac{QU}{QS}=\dfrac{UV}{SR}\\ \\\dfrac{QU}{QU+US}=\dfrac{1.5US}{1.5US+US}=\dfrac{1.5}{2.5}=0.6

so

\dfrac{UV}{SR}=0.6\Rightarrow UV=0.6SR=0.6\cdot 20=12
