Here is a table of values for y = f(x).
DanielleElmas [232]

the complete question in the attached figure

statements

case A) f(15)=8-----> is correct

for x=15

f(x)=8

case B) the domain of f(x) is the set {5,6,7,8,10,11,12,13}--> is not correct

because the domain of f(x) is the set {0,5,10,15,20,25,30,35,40}

case C) f(5)=6-----> is  correct

for x=5

f(x)=6

case D) the range for f(x) is all real numbers----> is not correct

because

the range of f(x) is the set {5,6,7,8,9,10,11,12,13}

the answer is

A and C

What is the missing length??
amid [387]

Answer

The missing length is 10

Step-by-step explanation:

Represent the missing length with x

The sides of the given shape are directly proportional.

Mathematically:

(15 + x) to (12 + 8) and x to 7

Represent as a ratio:

(15 + x) : (12 + 8) = x : 8

15 + x : 20= x : 8

Convert to fraction

\frac{15 + x}{20} = \frac{x}{8}

Cross Multiply:

(15 + x)*8 = 20 * x

120 + 8x = 20x

Collect Like Terms

20x - 8x = 120

12x = 120

Solve for x

x = \frac{120}{10}

x = 10

<em>The length of the missing side is 10</em>
