Debbie's checkbook balance is $-3,297.23, which shows an overdraft.

An overdraft occurs when the money (deposits) in Debbie's account does not exceed her payments or withdrawals.

While Debbie had a positive beginning balance, the ending balance shows an overdraft of $-3,297.23.

By this overdraft, Debbie's bank is extending her some short-term credit, which she should pay back with interest.

Beginning balance on checkbook =  $2,715.50

Checks for the month =                     $-5,298.13

Deposits for the month =                       $250.16

Payroll check =                                 $-2,980.66

IRS check =                                          $2,550

Auto insurance and utilities =               $-534.10

Ending balance on checkbook =     $-3,297.23

Thus, Debbie's ending checkbook balance will show an overdraft of $-3,297.23.

The third variable in systems of equations with more than two variables can be defined in terms of the other two (as for solution by substitution). This can be used to create two equations with two unknowns by substituting it into the remaining equations. The value of the third variable can then be determined using that answer. The use of this technology is demonstrated in the attached.

The last equation served as a definition, which was then applied to the first two equations. An algebraic solution can be solved using the same strategy.

Answer:

[tex]w \leq 1.9[/tex]

Step-by-step explanation:

The picture itself measures 6" by 8". Therefore, the area is 6 * 8 = 48 square inches.

All of the pieces of wood have the same width, and we know that two of them will be 6 inches long and two will be 8 inches long.

Therefore, the combined area of the pieces of wood will be 2 * 6w and 2 * 8w. This gives us 12w + 16w.

Now we can set up an inequality:

48 (area of picture) + 12w + 16w <= 100 (maximum area).

Simplify the left side of the equation to give us this:

[tex]48+28w\leq 100.[/tex]

We can move the 48 over to the other side to get [tex]28w \leq 100 - 48[/tex], which simplifies to [tex]28w \leq 56[/tex]. Now, you just have to divide both sides by 28 to get [tex]w\leq 1.857[/tex].

Rounding to the nearest tenth of an inch gives us 1.9 as the maximum width of the pieces of wood.

Answer:

x and y is 59 degrees

Step-by-step explanation:

You can find the angle next to 121 which is 59 degrees considering linear pair. Then, you can figure out y by doing corresponding angles and so this means that y is also 59 degrees. To find x, we know that x is vertical to y and that they are the same value. So, this means that x is 59 degrees as well. Hope this helps!

The factored expression of 4x^3 + 12x^2 + 3x + 9 is (4x^2 + 3)(x + 3)

Expressions are mathematical statements that are represented by variables, coefficients and operators

The expression is given as

4x^3 + 12x^2 + 3x + 9

Group the expression in 2's

So, we have

4x^3 + 12x^2 + 3x + 9 = (4x^3 + 12x^2) + (3x + 9)

Factor each group

So, we have

4x^3 + 12x^2 + 3x + 9 = 4x^2(x + 3) + 3(x + 3)

Rewrite as

4x^3 + 12x^2 + 3x + 9 = (4x^2 + 3)(x + 3)

Hence, the factored expression is (4x^2 + 3)(x + 3)

From the complete question (added at the end of the solution), the equation of the parabola is given as

y = x²

When a parabola has the form of y = x², then the vertex of the parabola is

Vertex = (0, 0)

Set x > 0 to determine the points to the right

When x = 1

y = 1² = 1

When x = 2

y = 2² = 4

Set x > 0 to determine the points to the left

When x = -1

y = -1² = 1

When x = -2

y = -2² = 4

So, the points are

(1, 1), (2, 4), (-1, 1) and (-2, 4)

Given the function of the rate of change of the population:

The integral of this function will be the value of the population growth of the town from 1990 to 2010. This is because P(t) is the rate of change of population, its integral will be the antiderivative, that is the population of the town.

To calculate the change in population we have to find the integral from 5 to 10 of P(t):

The change in population can not be a decimal number, so we can round it to 1162.

To calculate the population in 2020 we have to find the integral from 0 to 30 of P(t) and then add it to 10000 which was the initial population (we already know the integral so we're just going to evaluate it):

It means that the population in 2020 is 18221 (Remember that we round it because it is not possible to have a decimal value for the population of the town).

Given:

650 lb of coffee is sold when the price is $4 per pound,

400 lb of coffee is sold at $8 per pound.

To find:

A) List the data points

B) The slope of line joining the points

C) Interpretation of meaning of slope of line

D) linear equation of data using point slope form

E) Using the function we need to predict the number of consumers buying at $6 per pound

Step-by-step solution:

A) Data points of the given data:

Data points:

(4,650) and (8,400)

B) The slope of the line joining the points:

C) Interpretation of meaning of slope of line:

Slope here means that:

When there is an increase in the price of coffee then the weight of coffee decreases.

Weight per dollar of coffee decreases at the rate of 62.5

D) linear equation of data using the point-slope form:

Applying point-slope form:

y - y1 = m(x - x1)

y - 650 = -62.5(x - 4)

y = -62.5x + 900

In function notation it can be represented as:

S(P) = -62.5P + 900

E) Using the function we need to predict the number of consumers buying at $6 per pound

To predict that, we will simply put the value of P equal to 6 in the given function:

S(P) = -62.5P + 900 At P = 6

S(P) = -62.5(6) + 900

S(P) = 525

Thus we can say that 525 customers will buy at $6 per pound.
