Answer:

-x=1 1/3

Step-by-step explanation:

x-(4x-5y)=(5y+4)

x-4x+5y=5y+4

-3x+5y=5y+4

5y-5y=0

-3x=4

x=4÷3

A thermal insulated sleeve is used to cover the lateral surface of a hot water heater to help improve efficiency. The hot water

hjlf

Answer:

$V=18,369\ in^3$

Step-by-step explanation:

step 1

Find the lateral surface of the cylinder (hot water tank)

The lateral area is given by the formula

$LA=2\pi r h$

we have

$r=13\ in\\h=75\ in$

substitute

$LA=2\pi (13)(75)$

$LA=1,950 \pi\ in^2$

step 2

Find the volume of fiberglass composite needed

Multiply the lateral area by the thick

$V=1,950 \pi (3)$

$V=5,850 \pi\ in^3$ -----> exact value

assume

$\pi=3.14$

$V=5,850(3.14)=18,369\ in^3$

Make a mapping diagram for the relation. {(-2, -6), (0, 3), (1, -5), (5, 0)}

Finger [1]

we know that

A mapping diagram shows how the elements are paired. Its like a flow chart for a function, showing the input and output values.

The input values are the elements of the domain and the output values are the elements of the range.

In this problem

Input Values (Domain) are

$[-2, 0, 1,5]$

Output Values (Range) are

$[-6, 3,-5,0]$

therefore

the answer is

The correct answer is the second diagram

see the attached figure
