16 it will be a positive number because it's the opposite of |-8| but it was -|8| then it would be a neg number

Beginning with the graph of f(x) = x2, what transformations are needed to form g of x equals one third times the quantity x plus

laila [671]

To transform f(x) into g(x) we need to use addition, subtraction and multiplication.

Given f(x)= $x^{2}$ and g(x)= $x/3+3(x^{2} -3)$

We need to transform function f(x)into g(x).

A function refers to a relation which expresses relationship between two variables. It contains one value for each value of x. If there are more than one value for one value of x then it is not said to be a function.

f(x)= $x^{2}$ , g(x)= $x/3+3(x^{2} -3)$

To transform f(x) into g(x) we need to follow the following steps:

First subtract 3 from f(x).
Then multiply the expression received from above step by 3.
Next step is to add x/3 to the expression received from the above step.
Now we will get the g(x)= $x/3+3(x^{2} -3)$ .

Hence we have to use addition, subtraction and multiplication for transformation.

Will mark brainliest plz help

Answer:

A. 5b > 650 + 2.25b; B. 237 brownies

Step-by-step explanation:

A. Set up the inequality

Let b = the number of brownies. Then

Cost = 650 + 2.25b

Sales = 5b

Profit = Sales - Cost

To make a profit, we must have

Sales - Cost > 0 or

5b > 650 + 2.25b

2. Solve the inequality

$\begin{array}{rcl}5b & > & 650 + 2.25b\\2.75b & > & 650\\b & > & \dfrac{650}{2.75}\\\\& > & 236.4\\\end{array}\\\text{Albert can't sell a fraction of a brownie, so b $>$ 237}\\\text{Albert must sell at least $\large \boxed{\textbf{237 brownies}}$ to make a profit.}$

3. Check

$\begin{array}{rcl}5 \times 237 & > & 650 + 2.25 \times 237\\1185 & > & 650 + 533.25\\1185 & > & 1183.25\\\end{array}$

OK.

A family spent $7845 on vacations this year. If this family decreases the amount it spends on

jolli1 [7]

Answer:

$6,824.03 is the amount the family will spend on vacations in 5 years

Step-by-step explanation:

The formula A = P(1 + r)^n is appropriate in this problem, with the understanding that A represents the amount the family will spend on vacations in n years and P is the current spending amount. Then:

A = ($7,845)(1 - 0.0275)^5, where we use -0.0275 to indicate that the amount DECREASES by 2.75% annually. Simplifying this formula, we get:

A = ($7,845)(0.9725)^5, whose value to the nearest cent comes out to:

A = $6,824.03 is the amount the family will spend on vacations in 5 years.

Question 1

Solnce55 [7]

The probability to get heads on all three quarters is 1/8.

Step-by-step explanation:

Given data :

Leslie has three quarters.
Each quarters have 2 sides namely the Head and the Tail.

It can be determined that :

The total number of possible outcomes you can get from the three quarters with two sides = 2³ ⇒ 2×2×2 ⇒ 8 total outcomes.

If she drops all three of the quarters in the same time, there will be a total of 8 different outcomes.

These 8 outcomes include (T,T,T), (H,T,T), (H,H,T), (T,H,H), (T,T,H), (T,H,T), (H,H,T), (H,H,H).

From the above shown different possible outcomes, you need to find the probability that all three quarters will land on Heads.

Probability(3 heads)= No. of outcomes with 3 heads / Total no.of outcomes

We know that,

The no.of outcomes with 3 heads is only 1.
The total no.of outcomes is 8.

⇒ P( 3 heads ) = 1/8

The probability to get heads on all three quarters is 1/8.
