Consider the function below. Find f(8)
Answer: The First one isn't valid
The second one is equal to 9
Answer:
Step-by-step explanation:
Substitute 8 for x
3(8) - 1
Solve:
3 x 8 = 24
24 - 1 = 23
Next, substitute for x in the inequality with the answer you just made. See if it's true.
23 [tex]\leq[/tex] 2
The inequality is NOT TRUE
Same thing for the next one
1/2(8) + 5
Solve:
1/2 x 8 = 4
4 + 5 = 9
Substitute for x in the inequality with the answer you just made. See if it's true.
9 > 2
This inequality is TRUE

Juan cuts a piece of rope that is 1/6 meter long into 2 equal pieces.
What is the length of each shorter piece of rope?
Enter your answer as a fraction in simplest form by filling in the boxes.
[tex]\frac{x}{y} \\[/tex]
Answer:
1/12 a meter long
Step-by-step explanation:
You have to multiply The Denominator by the amount of rope your cutting making it which in your case its 2 pieces so multiply 2 by 6 equals 12 and so replace 6 with 12 and that's your answer. good luck on your test or whatever it is!

Step-by-step explanation:
The cost to mail a letter is a base charge of $0.42 plus $0.17 for each ounce. Write an expression to represent the cost for mailing a letter that is w ounces. Then find the cost for mailing a letter that is four ounces.
0.17 + 0.42 w; $1.85
0.17 + 0.42 w; $2.36
0.42 + 0.17 w; $1.10
0.42 + 0.17 w; $2.36
Answer:
0.42+ 0.17w); 1.10$
It would cost us $1.10 to send a 4-ounce letter.
Answer:
C) 0.42 + 0.17 | w: $1.10
Step-by-step explanation:
Note that amount of ounces is denoted by the variable "w". The cost per ounce is $0.17, while the constant charge (charge doesn't change per ounce) is $0.42.
Set the equation:
(Cost per ounce x Amount of ounces) + Constant charge = Total charge:
(0.17x) + 0.42 = Total Charge
Total Charge = 0.17x + 0.42
Next, you are solving for the cost of 4 ounces. Plug in 4 in the variable, x.
Total Charge = 0.17x + 0.42
Plug in 4 for x.
= 0.17(4) + 0.42
Follow PEMDAS, First, multiply, then add:
= (0.17 * 4) + 0.42
= 0.68 + 0.42
= 1.10
~
C) 0.42 + 0.17 | w: $1.10 is your answer.

Help!!!! the integer that makes the following addition sentence true.
? + (-11) + 12 + =-16
Answer:
-17
Step-by-step explanation:
I will represent the question mark with the variable [tex]x[/tex].
[tex]x - 11 + 12 = -16[/tex]
To solve for [tex]x[/tex], we need to isolate it.
To do this, subtract 12 from both sides.
[tex]x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28[/tex]
Then, add 11 to both sides.
[tex]x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17[/tex]
[tex]x = -17[/tex]
So, the integer that makes the equation true is -17.
w-4/h-4=4/3 can someone please answer this its for homework someone told me it was 8 but i got 12
the letter "w" represents a variable, and the letter "h" also represents a variable. The goal is to solve for either "w" or "h" by using the given information and the rules of algebra.
To solve this equation, we can start by multiplying both sides of the equation by 3 to eliminate the fraction on the right side:
w-4/h-4=4/3
3(w-4/h-4)=3(4/3)
This simplifies to:
3w-12/3h-12=4
Next, we can simplify the expression on the left side of the equation by combining like terms:
3w-12/3h-12=4
3w-3h=-8
Finally, we can solve for either "w" or "h" by using the given information and the rules of algebra. For example, we can solve for "w" by adding 3h to both sides of the equation:
3w-3h=-8
3w=-8+3h
w=-2+h
This means that the value of "w" is equal to the value of "h" minus 2. Alternatively, we could solve for "h" by adding 3w to both sides of the equation:
3w-3h=-8
-3h=-8+3w
h=2-w/3
This means that the value of "h" is equal to 2 minus the value of "w" divided by 3.

Answer
(2,3)
Step-by-step explanation:
9x-7y=-3
-9x+15y=27
-------------------
8y=24
divide by 8 on both sides
y=3
now using substitution, you can now work out x
9x-7y=-3
9x-7(3)=-3
9x-21=-3
add 21 on both sides
9x=18
then divide my 9 on both sides
x=2

Answer:
Step-by-step explanation:
You add 3/5 to -4/7 by finding the least common denominator (the bottom part of the fraction).
LCD is found by listing the multiples of the denominators and finding the common one.
5: 5, 10, 15, 20, 25, 30, 35
7: 7, 14, 21, 28, 35
For 3/5 you would multiply the numerator (the top part of the fraction) and denominator by 7, getting 21/35.
For -4/7, you would multiply the numerator and denominator by 5, getting -20/35.
21 + (-20) = 21 - 20 = 1
1/35
The final answer is that n is less than or equal to 1/35.

Explain how to use a pattern to find the product of a decimal
Answer: Remove, Multiply, Add (RMA)
Step-by-step explanation:
I'll share a method I use. it is removed, multiply, and add. first, you have to remove the decimals from the problem, multiply them, and add the decimals back into the problem. count the number of how many numbers are behind the decimal. for example, let's take 3. after you multiply, count three spaces to the left and place the decimal. let's take 3.12 x 2.7. first, remove the decimals. after you do that, you're left with 312 x 27. do the multiplication, and then count the number of how many numbers are behind the decimals. so, that would be three. your answer for the mutiplication problem is 8,424. since there are three spaces, you would count one, two three. to the left of 8,424. therefore, the answer is 8.424
