Answer:

4. The expression has a value of 1/36 . True

5. An equivalent expression is (6)^5. (6)^- 7  True

Step-by-step explanation:

Not true. The 6 without an exponent is equivalent to the 6 having a 0 exponent.

6 · (6)^0 · (6)^–3

= 6.1.1/216

= 1/36

= (6)^-2

2. The sum of exponents is 2.  

False ( the sum of exponents is -2)

3.Multiply the exponents to solve the expression .

False when the bases are the same the exponents are added or subtracted.

4. The expression has a value of 1/36 .

True

5. An equivalent expression is (6)^5. (6)^- 7

Answer:

[tex] a^4 + 5a^2 b - 14b^2[/tex]

Step-by-step explanation:

[tex](a^5 b^5 + 5a^3 b^6 - 14ab^7) \div ab^5 \\ \\ = \frac{(a^5 b^5 + 5a^3 b^6 - 14ab^7) }{ab^5}

\\ \\ = \frac{a {b}^{5} (a^4 + 5a^2 b - 14b^2) }{ab^5} \\ \\ = a^4 + 5a^2 b - 14b^2[/tex]

By definition, the correct answer is the last option: the inverse of the function f(x) = 4x is h(x)= [tex]\frac{1}{4}[/tex]x.

The inverse or reciprocal function of f(x) is called another function f⁻¹(x) that satisfies: If f(x)=y , then f⁻¹(y)=x.

To build or calculate the inverse function of any function, one of the ways to do it is to interchange the variables x and y, and use a combination of algebraic methods in order to isolate the variable "y".

Being f(x)=y=4x, to calculate the inverse, in first place you interchange the variables x and y:

f(y)=x=4y

Isolating the variable y, you get:

h(x)=x÷4= [tex]\frac{1}{4}[/tex]x

Finally, the correct answer is the last option: the inverse of the function f(x) = 4x is h(x)= [tex]\frac{1}{4}[/tex]x.

Answer:

The reflexive property of equality states that any number is equal to itself. This property has no proof, as it is the fundamental building-block of all other proofs.

Step-by-step explanation:

Answer:

Option (D)

Step-by-step explanation:

System of equations has been given as,

2y - 4x = 6

y - 2x = 3 [Dividing both sides of the equation by 2]

y = 2x + 3 ------(1) [Slope-intercept for of the equation]

y = 2x + 3 ------(2)

Since, both the equations are same,

System of equations will have infinitely many solutions.

Therefore, Option (D) will be the correct option.

Answer:

120 degrees

Step-by-step explanation:

To find m<1 we must first find the other angles.

First, find m<CDB. To do this use the complementary angle 130. So m<CDB=180-130, which means m<CDB=50.

Then find m<2, to do this remember that all triangles equal 180. So to find m<2 solve the equation m<2=180-(70+50), which equals 60 degrees.

Finally find m<1 the same way you found m<CDB, using the complementary angle 2. m<2=180-60, therefore m<1=120.

Answer:

120

Step-by-step explanation:

25% amount of money increased in her bank account.

Here,

Erica’s bank account increased from $1,200.00 to $1,500.00.

We have to find the percent of amount of money in her bank account increase.

What is Percent?

Percentage is a fraction or a ratio in which the value of whole is always 100.

Now,

Erica’s bank account increased from $1,200.00 to $1,500.00.

Increased money = $1,500 - $1,200 = $300

Percentage of increased money = [tex]\frac{300}{1200} * 100 = 25[/tex]

Hence, 25% amount of money increased in her bank account.

Answer:

2/3y

Step-by-step explanation:

If the class usually has y students and has 2/3 today, it can be represented by 2/3y.

Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.

So, in terms of y, 2/3y represents the number of students in class today.

Answer: 175% or 75% more in price

Step-by-step explanation:

There was a 75% of markup in the price.

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.

Given that, The store bought a table for $200, and sold it for $350, we need to find the percentage of markup in the price,

percentage of markup in the price =

(final price - original price)/(original price)x100

final price = $350, original price = $200

Markup in price = $350-$200 = $150

percentage of markup in the price = 150/200x100 = 75%

Hence, There was a 75% of markup in the price.

Answer:

1 and 9/20

Step-by-step explanation:

add your fractions together 7/10 + 3/4

make them have the same denom 14/20 + 15/20

so its 29/20

to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.

the answer is 1 and 9/20

work:

7/10km = 14/20km

3/4km = 15/20km

15/20+14/20=29/20km

29/20 as a mixed number is 1 and 9/20.

Jada plans to serve milk and healthy cookies for a book club meeting. She is preparing 12 ounces of milk and 4 cookies per person. Including herself, there are 15 people in the club. A package of cookies contains 24 cookies and costs $4.50. A 1-gallon jug of milk contains 128 ounces and costs $3. Let represent number of people in the club, represent the ounces of milk, represent the number of cookies and represent Jada's budget in dollars. Select all of the equations that could represent the quantities and constraints in this situation.

â m= 12(15)

n represents the number of people

m represents the ounces of milk

& 44.50) = C

c represents the number of

e b=2(3) + 3(4.50)

The equations that could represent the quantities and constraints in this situation are:

a) m = 12(15)

e) b = 2(3) + 3(4.50)

Step-by-step explanation:

Jada plans to serve milk and healthy cookies for a book club meeting

She is preparing 12 ounces of milk and 4 cookies per person

There are 15 people in the club

A package of cookies contains 24 cookies and costs $4.50

A 1-gallon jug of milk contains 128 ounces and costs $3

Let us represents number of people in the club by n

The the ounces of milk = m

The number of cookies = c

Jada's budget in dollars = d

y = 12(15)

She is preparing 4 cookies per person

4n = c

Since A package of cookies contains 24 cookies

She needs = 15 × 4 = 60 cookies

60 ÷ 24 = 2.5

Hence, approximately, she has to buy 3 packages of cookies

She needs = 15 × 12 = 180 ounces of milk

A 1-gallon jug of milk contains 128 ounces

180 ÷ 128 = 1.406

She needs to buy 2 A 1-gallon jug of milk

Note that: from the question

The cost of each jug of milk is $3

The cost of each package of cookies is $4.50

b represents Jada's budget in dollars

b = 2(3) + 3(4.50)
