What is the y-intercept of the quadratic function
f(x) = (x – 8)(x + 3)?

(8,0)
(0,3)
(0,–24)
(–5,0)

Answer:

18/24 = 3/4 (3/4 is the answer when simplified already)

Hope this helps :)

Explanation below.

Step-by-step explanation:

1. Use the Keep, Change, Flip (KCF) method.

- 2/3 ÷ (- 8/9)

K C F

2. Solve by multiplying numerator and denominator.

- 2/3 × (- 9/8)

= 18/24

3. Simplify if needed by dividing the numerator and denominator by 6.

18/24 = 3/4

The arrows shows the function is a one-to-one function. Each range value has only one domain value it is paired to.

If each range value (output value) is paired exactly with a domain value (input value), the mapping that is said to represent a one-to-one function. It is a one-to-one mapping.

In the mapping diagram given, the arrows tells us that the function is one-to-one mapping/function. This means that exactly one element of the output (range value) is paired with one input (domain value).

Thus, we can conclude that the arrows shows the function is a one-to-one function. Each range value has only one domain value it is paired to.

Quartile deviation in Statistics can be defined as the statistic that measures the dispersion. Here, the Dispersion is the state of getting dispersed or spread. Statistical dispersion means the extent to which numerical data is likely to vary about an average value. In other words, dispersion helps to understand the distribution of the data Suppose Q1 is the lower quartile, Q2 is the median, and Q3 is the upper quartile for the given data set, then its quartile deviation can be calculated using the following formula.

QD = (Q3 – Q1)/2

In the next section, you will learn how to calculate these quartiles for both ungrouped and grouped data separately.

For an ungrouped data, quartiles can be obtained using the following formulas,

Q1 = [(n+1)/4]th item

Q2 = [(n+1)/2]th item

Q3 = [3(n+1)/4]th item

Where n represents the total number of observations in the given data set.

Also, Q2 is the median of the given data set, Q1 is the median of the lower half of the data set and Q3 is the median of the upper half of the data set.

The given data is that is first quartile is lowest off 25% of the numbers and second quartile. It is between 0% and 50% of two median. And thought quartile is the rope percent two 75% ward court trial is the highest 25% of numbers. For example, spores, the distribution spores, the distribution of math scores not so of course in a class of 19 students of 19 students in ascending order is with 39 60 6 to 5 65, 68, 69, 70 72, 75, 75, 76, 77 81, 84, 87, 90 95, 98. No postmark the median and Q two which is in this case in this Case is the 10th value and value that is 70 five. You won is the central. Mhm point between the smallest to score smallest school and median in this case. Do you want Falls between the two post and fifth school? That is 68. The average of fifth and six score is fifth plus sixth way two. That is 68 plus 69/2 which is equal to 68.5. No Q three is middle value between 23 and I used to score is 84. No Q three Is 82 plus 84/2. That is 83. No. Do you want the hosts as that? 25% of the scores ah less then 68 and 75% of the of course are greater and you do the median is the 50th percentile and shows that, and shows that 50% of the scores are less than 75 and 50% of the scores are above 75 and finally, you're three the 75th percentile. It reveals that 25% of the scores, odd greater than 75%, are less than it would be full.

9 and 10are two integers is √85 between.

The number zero (0), a positive natural number (1, 2, 3, etc.), or a negative integer denoted by a minus sign (1, 2, 3, etc.) are all examples of integers. The equivalent positive numbers' additive inverses are the negative numbers. The boldface Z or blackboard bold symbol is a common way to represent the set of integers in mathematical expressions.

The set of all natural numbers, N, is a subset of the set of all rational numbers, Z, which is a subset of the set of all real numbers, R.

Z is a countably infinite number, much like the natural numbers. A real number that may be expressed without a fractional component is said to be an b.

A real estate agent commission on the house that she sold $346,000 is $38,060.

Given that, a real estate agent works on 11% commission.

We need to find out what is her commission on the house that she sold $346,000.

The commission is a percentage of total sales as determined by the rate of commission. Commission=Rate of commission⋅Total sales. To find the commission on a sale, multiply the rate of commission by the total sales.

Now, the commission on the house=11% of 346,000

=11/100 × 346,000

=0.11 × 346,000

=$38,060

Therefore, a real estate agent commission on the house that she sold $346,000 is $38,060.

The interpretation of the above quotation in terms of what is essential and discretionary vacation expenses implies that there are some unnecessary vacation expenses while others are compulsory vacation expenses.

Discretionary expenses refer to outflows that a person can avoid if they choose.

On the other hand, one cannot avoid nondiscretionary expenses after choosing a spending activity because they are necessary and compulsory.

An example of nondiscretionary expenses are taxes, the cost of meals, and utility expenses. An example of a discretionary outflow is charitable donations.

Answer:

a) if x = 2, y = -1

b) y = 5

Step-by-step explanation:

12x - 4y = -20 Let's substitute x = 2

12(-2) - 4y = -20 Multiply

-24 - 4y = -20 Add 24 to each side

-4y = 4 Multiply each side by -1

4y = -4 Divide by 4

y = -1

now to solve for y in general:

12x - 4y = -20 Subtract 12x

-4y = -20 - 12x Divide by -4

y = 5 + 3x Sub 0

y = 5 + 3(0)

y = 5

Answer:

smaller number is 26

larger number is 28

Step-by-step explanation:

This is a system of equations that we can solve by substitution.  Let x = the smaller number and y the larger.  The two equations are:

x + y = 54

x + 5y = 166

Solve the first equation for y and use that in the second equation.

y = 54 - x (we will plug this in for y in the second equation and solve that for x)

x + 5(54 - x) = 166

x + 270 - 5x = 166

-4x = 166 - 270

-4x = -104

x = 26

Plug this into x + y = 54 and solve for y

26 + y = 54

y = 54 - 26

y = 28

Mr. Alfonso will save $3 if he orders the shrimps from shrimpies.

Now, for the given question;

The cost of 3 pounds of shrimp at Earl's shrimp hut = $38.25.

3 pounds   ---------> $38.25

Divide both sides by 3.

1 pound ------------>$12.75

Multiply 12 on both side;

12 pounds -------------> $153.

The cost of 4 pounds of shrimp at shrimpie's for 50.00.

4 pounds   ---------> $50.00.

Divide both sides by 4.

1 pound ------------>$12.5

Multiply 12 on both side;

12 pounds -------------> $150.

Cost difference  =  Earl's shrimp hut - shrimpie

Cost difference  = $153 - $150 = $3.

Therefore, Mr. Alfonso will save $3 from the purchase of 12 pounds of shrimp from shrimpies.
