Answer:
Your math teacher deserves to be fired.
The example for this is 1.23 × 4.5 (none of your questions, I know)
Anyway we want to do this lining up the digits like so:
1.23
× 4.5
NOT
1.23
× 4.5
Now we want to multiply all the digits (1, 2, 3) in the top number (1.23) by the 5 in 4.5. We'll start with the 3 in 1.23.
Since 3 × 5 is equal to 15, we will put the ones digit of 15, 5, in that place.
1.23
× 4.5
5
Now we need to carry the 1 in the 15 to be used in 2 (of 1.23) multiplied by the 5 (in 4.5). Now we will get 2 × 5 + 1 which equals 11. We carry the 1 in 11 to the next part.
[tex]_{1}[/tex]
1.23
× 4.5
15
So we currently have the digits 15 for our answer. Now we move to the next part where we do 1 × 5 + 1 which is equal to 6. Our problem is now:
[tex]_{1}[/tex]
1.23
× 4.5
615
Now we can move to the next row where we do the exact same thing where we multiply the digits in 1.23 BUT instead of 5, we now multiply them each by 4 since our number is 4.5. However this is different, before starting to multiply, we need to put a 0 in the ones digit of the 2nd row of our answer like so:
[tex]_{1}[/tex]
1.23
× 4.5
615
+ 0
Now we can start to multiply.
[tex]_{1}[/tex]
1.23
× 4.5
615
+ 20
then
[tex]_{1}[/tex]
1.23
× 4.5
615
+ 920
then
[tex]_{1}[/tex]
1.23
× 4.5
615
+4920
Now we are almost at our solution, we need to now add our 615 and 4920. That then is equal to 5535. Now since we have 3 digits in total in 1.23 & 4.5 BEHIND the decimal point, we need to put a decimal point 3 digits to the right of 5535 so then it becomes 5.535. Hopefully, this helps? I didn't answer them immediately because if you never learn how to do long multiplication (what this is called) then you'll likely fail at all other math. Trust me, I know, I've done that before, I hope you don't make the same mistake because the feeling when everyone else is ahead of you and you're still at the basics is horrible.
Anyway answers for your question because I think I'll likely be reported for not answering your question:
40.725 | 9.576 | 17.442 | 45.29
79.294 | 30.736 | 30.8 | 31.5

1: n/-3 - 8 < 17
2: n/-2 + 11 > 17
Answers
Answer:
1: n > -75
2: n < -12
Step-by-step explanation:
1: n/-3 - 8 < 17
n/-3 (- 8 + 8) < 17 + 8
n/-3 < 25
n/-3(-3) < 25(-3)
n < -75
n > -75 (switch symbol when you divide or multiply by a negative number)
2: n/-2 + 11 > 17
n/-2 (+ 11 - 11) > 17 - 11
n/-2 > 6
n/-2(-2) > 6(-2)
n > -12
n < -12 (switch symbol when you divide or multiply by a negative number)

If a function 'f' is translated by 'k' units down, image function 'g' will be,
g(x) = h(x) - 3If the function 'g' gets shrink by a factor 'm', the new function 'k' will be,
k(x) = [tex]m[g(x)][/tex] where, 0 < m < 1Following these rules image of the function 'f' given in the question will be g(x) = [tex]\frac{1}{3}x-1[/tex]
Function given in the question is,
f(x) = xIf the function f is translated by 3 units down, image function 'h' will be,
h(x) = f(x) -3
h(x) = x - 3
If the image function is vertically shrink by a factor of k, equation of the image function will be,
g(x) = [tex]k[h(x)-3][/tex]
where, k = [tex]\frac{1}{3}[/tex],
g(x) = [tex]\frac{1}{3}}(x-3)[/tex]

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The cost difference between the new and refurbished computer is $800.00 - $640.00 = $160.00. This means that you would save $160.00 by buying the refurbished computer instead of the new one.
Let's say you work for "x" hours, then your gross pay will be:
A = 10x dollars
Your FICA deduction will be 7.65% of your gross pay:
0.0765 ( 10x ) = 0.765x dollars
Your federal tax withholding will be 12% of your gross pay:
0.12 ( 10x ) = 1.2x dollars
Your state tax withholding will be 8% of your gross pay:
0.08 ( 10x ) = 0.8x dollars
The total amount of taxes that will be deducted from your paycheck is the sum of these three amounts:
0.765x + 1.2x + 0.8x = 2.765x dollars
So your net pay will be:
10x - 2.765x = 7.235x dollars
On simplifying the equation , we get
Now, we can calculate the number of hours you would need to work to pay for the new computer:
800 = 7.235x
x ≈ 110.5 hours
Hence , the number of hours is x = 111 hours
