Given data:

The given expression is -x^2-9x-9=0.

The descriminant of the given equation is,

Thus, the descriminant of the given equation is 45.

Solution:

The slope-intercept form of a line with slope m and y-intercept b is given by the following formula:

On the other hand, the slope m is given by the following equation:

where (X1,Y1) and (X2,Y2) are points on the line. In this case, we can take the points:

(X1,Y1) = (1,2)

(X2,Y2) = (-1,-1)

replacing this data into the slope equation, we get:

thus, the slope of the line would be:

now, replacing this into the slope-intercept form of the line we get:

EQUATION 1

We only need to find the y-intercept b. For that, take any point on the line, for example (x,y) = (1,2), and replace it into the previous equation:

this is equivalent to:

solving for b, we get:

that is:

finally, replacing this into the EQUATION 1, we get:

Answer:A returned check

Step-by-step explanation:

Answer: D. bouncing a check

Bouncing a check

When a check is deposited in a bank, or when it is written out to a store teller to ultimately deposit in the store bank, the funds are tracing back from an origin bank account. When the check bounces a fee is then charges by both the bank out of which the check is written (for non-sufficient funds) and by the payee. If the payee is a store they will often charge fees that are charged back to them by their bank of deposit."

Utilizing differentiation, the biggest value of y=0 in the system's solution set.

One of the two fundamental concepts of calculus is differentiation. Differentiation is a method for finding a function's derivative. Differentiation is a mathematical technique used to calculate the instantaneous rate of change of a function based on one of its variables. Velocity, or how quickly a distance varies in respect to time, is the most common example. Differentiation's opposite is finding an antiderivative.

Differentiating the 1st equation, we get

x=5.5

Putting back in the equation.

y = -5.75

and differentiating the 2nd equation, we get

x=3

The probability that one friend is pregnant with identical twins, and one friend is pregnant with fraternal twins is 0.000045.

From the information illustrated,

Let A = event that one friend is pregnant with identical twins, and note that P(A)=0.0045.

Let B = event that the other friend is pregnant with fraternal twins, and note that P(B)=0.01.

Therefore, the probability will be gotten by using the multiplication for two independent events. This will be:

= P(A) × P(B)

= 0.0045 × 0.01

= 0.000045

The remaining work can be completed in if 2 printing machines of a printing house can complete the printing work in 20 days, After printing the books for 8 days, if 1 more machine was added, is 8 days.

In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation.

Given:

2 printing machines of a printing house can complete the printing work in 20 days,

After printing the books for 8 days, if 1 more machine was added,

Assume the total work is x,

Calculate the amount of work done in 8 days by both machines as shown below,

The amount of work done in 8 days = x / 20 × 8

The amount of work done in 8 days = 2x / 5

Calculate the remaining work = x - 2x / 5

The remaining work = 3x / 5

Calculate the time taken to complete the remaining work,

Time = (3x / 5) / (3x / 40) = 8 days

Thus, the total time is 16 days.

By using implicit differentiation, we get dy/dx=(2x+cos⁡(xy)y)/(-xcos(xy)+2y)

What is implicit differentiation?

Implicit differentiation is the process to finding the derivative of the implicit function.

We have given,

y^2=x^2+sin⁡(xy)

Differentiate with respect to x, and using product rule

2y dy/dx=d/dx(x^2+sin⁡(xy))

2y dy/dx=(dx^2)/dx+(dsin(xy))/dx

2y dy/dx=2x+cos⁡(xy)(d(xy))/dx

2y dy/dx=2x+cos⁡(xy)[y+x dy/dx]

2y dy/dx=2x+ycos(xy)+xcos⁡(xy)dy/dx

2y dy/dx-xcos(xy)  dy/dx=2x+ycos(xy)

On simplification, we get

dy/dx=(2x+xcos(xy))/(-xcos(xy)+2y)

2. The lengths are given as follows:

3. The length of segment AD is of 5 units.

When two points have one equal coordinate, as is the case in this problem for AB, CD and BC, the distance is given by the subtraction of the different coordinate.

Hence, considering the coordinates of the vertices on the given image, the distances are given as follows:

The perimeter of a polygon is the sum of the lengths of all the outer sides of the polygon, hence:

P = AB + CD + BC + AD.

The perimeter in this problem is of 18 units, hence the length of AD is given as follows:

The term "interest" refers to the additional revenue received by the investor over and above the investment or the additional debt owed by the borrower over and above the amount borrowed. Simple interest and compound interest are the two different kinds of interest. The sorts of interests are covered in further detail in the interest formula. Let's explore the interest formula in further detail and go through several cases.

Interest Formula: What is it?

Simple interest and compound interest are both included in the interest formula. Interest is the cost a borrower pays a lender for a loan. This additional sum, or the interest, must be paid in addition to the loan itself. The Simple Interest Formula and the Compound Interest Formula are both discussed in the interest formula Compound Interest Formula. The interest formula for both is

This problem is a bit different. Instead of choosing one item from each of several different

categories, we are repeatedly choosing items from the same category (the category is: the

letters of the word MATH) and each time we choose an item we do not replace it, so there is

one fewer choice at the next stage: we have 4 choices for the first letter (say we choose A),

then 3 choices for the second (M, T, and H; say we choose H), then 2 choices for the next

letter (M and T; say we choose M) and only one choice at the last stage (T). Thus, there are

4 · 3 · 2 · 1 = 24 ways to spell a code word with the letters MATH.

Explanation:

Here, we want to get the fair prize of the game

From the question, there are 4 prizes

When reaching into the box, we can only pick 1

Assuming that each of the prizes have the same probability oof being picked, the probability of picking any of the prize is 1/4

Now, to get the fair price of the game (it is obviously positive as we do not know if the player has anything to lose)

We have to multiply the probability by each of the price tag, then sum

The fixed $30 unlimited calls charge for Plan 1 and the initial charge as well as a charge per call of $0.03 calls in Plan 2 gives;

a. The inequality that indicates the number of calls for which Plan 1 is more economical than Plan 2 is presented as follows;

30 > 15 + 0.03•x

Which gives;

x > 500

b. The meaning of the inequality, in part a. is that Plan 1 is more economical than Plan 2 when more than 500 calls are made

An inequality makes a comparison between two values that are not equal.

The given parameters are;

The billing plan for Plan 1 is presented as follows;

Charges, C = $30

The charges of the billing plan for Plan 2 is presented as follows;

Where;

x = The number of calls made per month

a. The inequality that can be used to find the number of monthly calls for which Plan 1 is more economical than Plan 2 is found as follows;

At the start of registration for each plan, we have;

Cost of Plan 1 = $30

Cost of Plan 2 = $15 + $0.03 × 0 = $15

Therefore, Plan 2 is initially more economical than Plan 1

At the point (or number of calls) at which the expenses for both plans are the same, we have;

30 = 15 + 0.03 × x

Which gives;

From the above equation, we have that after 500 calls, the expenses of both plans will be the same

The inequality that gives the number of calls for which Plan 1 is more economical than Plan 2 is therefore;

30 > 15 + 0.03•x

Which gives;

b. The meaning of the inequality, x > 500 is that Plan 1 is becomes more economical than Plan 2 when a person makes more than 500 calls in a month

The question is really asking for the unit rate but on a supposedly linear graph that is not to scale, so it is difficult to evaluate real rates.

Starting with the inequality:

We have two cases:

Case 1: 4x-6≥0

Since 4x-6≥0, then |4x-6| = 4x-6. Then:

Case 2: 4x-6<0

Since 4x-6<0, then |4x-6| = -4x+6. Then:

The solution set of the inequality is all the numbers x which are greater or equal to 1/2 AND lower or equal to 5/2:

The graph of the solution is a number line from 1/2 to 5/2 including the endpoints:
