Answer:

20 (.8) = 16

It takes him 16 minutes to walk to school.

This is because 80% as a decimal is .8 and you multiply that by how long it takes Person A to walk and you get 16.

Answer:

It 20 minutes for 80 percent so if we divided 80 by 20 =4if we timed it by 5 it will give us the other 20 percent so the answer is 4

What is the value of f(−1) when f(x)=2x+2

mart [117]

Answer:

Step-by-step explanation:

$f(x)=2x+2$

To find f(−1) , substitute the values of x that's - 1 into f(x). That is for every x in f(x) replace it with - 1

That's

$f( - 1) = 2( - 1) + 2 \\ = - 2 + 2$

We have the final answer as

$f( - 1) = 0$

Hope this helps you

A computer chip has dimensions of 8mm x 8mm. the scale drawing shows 4cm by 4cm. the answer is 1cm represents 2mm but I don't kn

Please help Which of the following inequalities is graphed on the coordinate plane?

Gekata [30.6K]

Answer:

The inequality which represents the graph is y ≤ -2x + 1 ⇒ A

Step-by-step explanation:

To solve the question you must know some facts about inequalities

If the sign of inequality is ≥ or ≤, then it represents graphically by a solid line

If the sign of inequality is > or <, then it represents graphically by a dashed line

If the sign of inequality is > or ≥, then the area of the solutions should be over the line

If the sign of inequality is < or ≤, then the area of the solutions should be below the line

Let us study the graph and find the correct answer

∵ The line represented the inequality is solid

∴ The sign of inequality is ≥ or ≤

→ That means the answer is A or B

∵ The shaded area is the area of the solutions of the inequality

∵ The shaded area is below the line

∴ The sign of inequality must be ≤

→ That means the correct answer is A

∴ The inequality which represents the graph is y ≤ -2x + 1
