Answer:

distributive propertyaddition (subtraction) property of equalityadditive identity element (properties of real numbers)division property of equalitymultiplicative identity element (properties of real numbers)

Step-by-step explanation:

A lot of math is about identifying and matching patterns. Often, the patterns have an associated vocabulary. It helps to learn the patterns and the associated words.

Pattern: a(b +c) ⇔ ab +ac . . . description: distributive property

Pattern: a = b ⇒ a +c = b +c . . . description: addition property of equality

Pattern: a = b ⇒ a/c = b/c . . . description: division property of equality

Patterns: a -a = 0; a + 0 = a . . . description: properties of the additive inverse and the additive identity element

Patterns: a×(1/a) = 1; a×1 = a . . . description: properties of the multiplicative inverse and the multiplicative identity element

When parentheses come or go, the distributive property is usually involved. In the second line, you need to recognize that -2(3y) = -6y and that -2(-7) = +14. The result on the left is from applying the distributive property to remove parentheses.

The third line differs from the second line in that -14 shows up on both sides of the equal sign. This is a clue that the addition (or subtraction) property of equality is involved.

The fourth line differs from the third in that +14-14 disappeared from the left side, and -4-14 was replaced with -18 on the right side. The sum of a number and its opposite is zero, a property of the additive inverse. The fact that -4-14 = -18 is a property of real numbers. (You have to decide the best drop-down choice for that line.)

The fifth line shows both sides of the equation divided by -6. The multiplication (division) property of equality lets you do that.

The last line shows a simplification of the previous one. Again, the properties of real numbers and of the multiplicative inverse are involved. (You have to decide the best drop-down choice for that line.)

Answers

Answer:

We are given the function h(y) = 4|y + 2| - 3

So, to get the value of h(-8), we just have to replace the y in the equation with -8

In functions, the variable in the parentheses next to the name of the function is the variable we have to replace since the function is defined in the terms of that one variable. When you do more advanced questions, you will encounter functions with more than 1 variable

h(y) = 4 | y + 2 | - 3

replacing y with -8 to get the output in terms of -8

h(-8) = 4 | -8 + 2 | -3

h(-8) = (4 * 6) - 3

h(-8) = 24 - 3

h(-8) = 21

The answer is 3⁷ because when you are multiplying exponents with the same base, you keep the base and add the exponents. an example of this would be 4² x 4³. To simplify the expression you ignore the base, which is 4, and add the 2 and 3 to get 4⁵. So the answer to your question is 3⁷.

Tracy goes on a 3 day and night school band trip. There is no cost for travel and each band member only pays half the cost of the hotel room. However, each person is responsible for the cost of their own meals. His portion of the hotel bill is $49 per night and Tracy leaves a 10% tip for the maid service. Before tax, Tracy spends $32 per day on eating out plus 15% of this amount in tips. If Tracy spends a total of $280.74 on the band trip, what percent tax was Tracy charged on his food?
a.
6%
b.
7%
c.
8%
d.
9%

Answers

Answer:

Step-by-step explanation:

The service tax that is given on the food each day is 9 %.

What does service tax mean?

The government levies a service tax on particular service transactions carried out by the service provider. Suppose x% service tax is levied on a good on $n then the total amount that is to be paid is $(n(1+x/100)).

How to solve the problem?

Let the percent service tax that is charged on food be x%.

The situation is The total expenditure is $280.74 which is $49 per day on the hotel bill for 3 days on which a 10% tip was given for the maid services each day.

$32 was spent each day on food plus 15% of that amount was given as a tip each day.

And x% of $32 was given on tax.

Then, the equation that best represents the given situation is

280.74/3=49+(0.10)(49)+32+(0.15)(32)+(x/100)(32)

Then 93.58=90.7+(32)(x/100)

⇒32x=2.88×100

⇒x=288/32=9%

Thus, the service tax that is charged on the food each day is 9 %.

A store buys 8 sweaters for $72 and sells them for $288. How many profit does the store make per sweater?

Answers

Answer:

$27 per sweater

Step-by-step explanation:

To solve this, all we need to do is subtract the profit made by the amount the store bought the sweaters for:

288 - 72 = 216

Now, we can divide this number by 8 to find how much profit the store made per sweater:

216 / 8 = 27

So, the store made a profit of $27 per sweater.

Hope this helps :)

Mk bud I’m your tutor so let’s do 8 x 72 which equals 576 Mk then they stood it for 288 each so let’s x it again 8 x 288 equals 2,304 so now let’s - 576 from 2,304. 2,404 - by 576 equals 1,728

Express each of these system specifications using predicates, quantifiers, and logical connectives, if necessary.

a. At least one console must be accessible during every fault condition.
b. The e-mail address of every user can be retrieved whenever the archive contains at least one message sent by every user on the system.
c. For every security breach there is at least one mecha- nism that can detect that breach if and only if there is a process that has not been compromised.
d. There are at least two paths connecting every two dis- tinct endpoints on the network.
e. No one knows the password of every user on the sys- tem except for the system administrator, who knows all passwords.

Answers

The system specification with predicates, quantifiers, and logical connectives are:

a. ∃C(x) ∀F(y) such that if F(y) is true, C(x) is true.

b. ∀U(x) (∃M(y) if ∀U(z), ∃M(w) is true, then E(x) is true).

c. ∀B(x) (∃D(y) D(y) can detect B(x) ↔ (∃P(z) ¬P(z) is true)).

d. ∀E(x, y) (∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect

E(x, y)).

e. ∀U(x) (¬P(x) is true, except for the system administrator who knows all passwords: ∀U(y) P(y) if y is the system administrator).

We have,

Let C(x) be the predicate "x is a console" and F(x) be the predicate "x is a fault condition".
