36x2(for the total amount of yarn for the width) would be 72. 112-72=40. Since it is a rectangle and the width should both be the same size, the length should be 20 inches. (20+20+36+36=112, so 20 inches is the correct answer.

Books spontaneously catch on fire in temperatures at or above 451, degree Fahrenheit. Write an inequality that is true only for
Brilliant_brown [7]
For this case, the first thing you should do is define a variable.
 We have then:
 t: temperature (degree Fahrenheit).
 We write then the inequation that adapts to the problem:
 t> = 451
 Answer:
 
an inequality that is true only for temperatures at which books spontaneously catch on fire is:
 
t> = 451

I NEED HELP IM CONFUSED
mihalych1998 [28]

Answer:

<h2>x=-2 or x=8</h2>

Step-by-step explanation:

Isolate by the x from one side of the equation.

|x-3|=5

x-3=-5 and x-3=5

1. x-3=-5

Add 3 from both sides.

x-3+3=-5+3

Solve.

-5+3=(-2)

x=-2

2. x-3=5

Add 3 from both sides.

x-3+3=5+3

Solve.

5+3=8

x=8

Therefore, the correct answer is x=-2 or x=8.

A woman works out by running and swimming. When she runs, she burns 7 calories per minute. When she swims, she
olga_2 [115]

The inequality that describes the calories burned is 7x + 9y ≥ 441

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

let x represent the number of minutes of running and y represent the number of minutes of swimming, hence:

7x + 9y ≥ 441

The inequality that describes the calories burned is 7x + 9y ≥ 441

If f(x) = x3, which graph represents g(x) = f(x) + 4?
Jlenok [28]

Answer:

From the attached diagram, it is clear that:

  • Red graph represents the function f(x) = x³
  • Blue graph represents the function g(x) =  x³+4

It is clear from the blue line graph, that when we add 4 units to the output of the parent function, it will be shifted 4 units up.

Step-by-step explanation:

Given the function

  • f(x) = x³

The graph of the function f(x) is attached below.

We know that when we add the number, let say h, to the function output, it means the graph is shifted 'h' units up.

So, when we add 4 units to the graph f(x), it means the graph will be shifted 4 units up.

Therefore, the graph g(x) = f(x)+4 will be result of shifting 4 units up.

The diagram graph of both f(x) and g(x) is attached below.

From the attached diagram, it is clear that:

  • Red graph represents the function f(x) = x³
  • Blue graph represents the function g(x) =  x³+4

It is clear from the blue line graph, that when we add 4 units to the output of the parent function, it will be shifted 4 units up.
