Answer:

The 6 lemons for 2.50 is the better deal.

Step-by-step explanation:

2*3=6

3*0.99=2.97

2.97>2.50

To calculate the percent increase in annual usage of cell phones, we can use the following formula:

Percent increase = [(new value - original value) / original value] x 100

where the new value is the current year’s usage and the original value is last year’s usage.

In this case, Nick found that residents used their cell phones for 217,470 minutes last year and 434,940 minutes this year. So we can plug these values into the formula:

Percent increase = [(434940 - 217470) / 217470] x 100

Percent increase = 100%

Therefore, there was a 100% increase in annual usage of cell phones.

I hope that helps! Let me know if you have any other questions.

Answer:

6670 divided by 2=3335 SOOOO the answer is  :3335

Step-by-step explanation:

If they used 50 percent of their phone time, they're using half of it. Therefore, 1/2 of 6670 is 3335.   YW

Yes it is linear since it's in the standard form Ax+By = C

A = 2

B = -8

C = 16

Answer:

yes it's linear.

Step-by-step explanation:

you can determine if it's linear by check if you can make the equation be :

y=mx+b

so first, you can change the equation 2x-8y=16 to 8y=2x-16

and then, you can take out the common fact 2, which would be 4y=x-8

at this stage, you can even devide the whole by 4, wich the equation would be y=1/4x-2 or

     y=1/4x+(-2) which is follow the equation y=mx+c, therefore, it is linear.

Answer:

Multiply the whole number with the denominator of the proper fraction. Add the numerator of the proper fraction to this product to obtain the numerator of the improper fraction.

Explanation:

Let us convert 3¼ into an improper fraction.

Numerator of the improper fraction = (3 × 4) + 1 = 13

The denominator of the fraction will stay the same = 4

Hence 3¼ converted into an improper fraction will be 13/4

Step-by-step explanation:

The required scenario in the below solution part would lead to the given equation 2r + 15 = 25. The correct answer would be option (C).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.

The equation is given in the question, as follows:

2r + 15 = 25

Let r be items you can buy at the concession stand.

You are going to the movies with some friends. You have $25 to spend. The movie costs $15 and each item at the concession stand costs $2. This equation shows how many items you can buy at the concession stand.

Thus, the required scenario in the above solution part would lead to the given equation.

Answer: -8r+12

Step-by-step explanation:

============================================

Explanation:

The outer term -2 is multiplied by each term inside

Then those results are added to get -8r + 12 as our final answer. We cannot combine these terms because they are not like terms.

I used the distribution property, also known as the distributive property.

That says a*(b-c) = a*b - a*c

In this case, a = -2, b = 4r, and c = 6.

Answer: She needs 1/2 a cup of oatmeal

Step-by-step explanation:

step 1. turn the 2 1/2 into a decimal to get 2.5

step 2. divide the decimal in half to get 1.25

step 3. add 2.5 + 1.25 = 3.75

step 4. take that answer and subtract it by how much oatmeal you have (3.25) to get 0.5       this means that you need half a cup of oatmeal to make 1 1/2 batches of oatmeal cookies

Answer:

g(x) = −4(one-half) Superscript x

Step-by-step explanation:

We want to reflex the function: f(x) = 4(1/2)^x across x-axis.

Reflection across x-axis is obtained multiplying parent function by minus one.

Therefore, the reflection of the function is: -f(x) = -4(1/2)^x = g(x)

The function that represents g(x), a reflection of f(x) = 4(one-half) Superscript x across the x-axis is g(x) = 4(1/2)^-x

Reflection occur when similar images acts as mirror images.

Given the function that represents f(x) as;

f(x) = 4(1/2)^x

If the function is reflected across the x-axis to produce the function g(x) is expressed as:

g(x) = 4(1/2)^-x

Hence the function that represents g(x), a reflection of f(x) = 4(one-half) Superscript x across the x-axis is g(x) = 4(1/2)^-x

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:

91ft^2

Step-by-step explanation:

A = w*l

first, solve for the bottom rectangle

w = 7ft

l = 8ft

7ft * 8ft = 56ft^2

then for the second rectangle

l = 5ft

w = 7ft

5ft*7ft = 35ft^2

total area = rectangle 1+2

so 35ft^2+56ft^2=91ft^2

Answer:

The answer for the Area of the shape is 91ft²

Step-by-step explanation:

Area of the shape =Area of Bigger rectangle+ Area of small rectangle

A=L×B+l×b

A=7×8+5×7

A=56+35

A=91ft²

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A
