(5)-(4) gives

4=2a

a=4/2=2

from (4)

6=5(2)+b

b=6-10=-4

from (1)

-5=2+(-4)+c

-5=-2+c

c=-3

y=2x²-4x-3

The collateral for the loan that Jordan signed the finance agreement, is nothing. There was no collateral.

A loan that doesn't require any sort of collateral is known as an unsecured loan. Lenders approve unsecured loans based on a borrower's creditworthiness rather than their assets as collateral. Personal loans, school loans, and credit cards are a few examples of unsecured loans.

Since secured loans are safer for lenders to approve than unsecured loans, unsecured loans need better credit scores.

Jordan most likely made a purchase with her credit card and so the finance agreement she signed would therefore likely be an unsecured loan with no collateral.

Answer: The total fee for an item priced at $300 is $80.

Step-by-step explanation:

We can use the two given points to find the slope (m) and one point to find the y-intercept (b) of the line representing the consignment fee equation.

We know the two points are (500, 120) and (800, 180)

slope (m) = (y2-y1)/(x2-x1) = (180-120)/(800-500) = 60/300 = 0.2

Now we can use one of the point to find y-intercept (b)

120 = 0.2(500) + b

b = 20

Now we can use point-slope equation to find the total fee for an item priced at $300

y - 120 = 0.2(x - 500)

y = 0.2x + 20

When the function, m ( x)  = x + 1 is graphed, the result is shown attached.

When graphing a function, you need to remember that x is the independent variable. This means that you need to come up with the values of x and then use these values to come up with the corresponding values of y or m (x ) using the function.

Assuming you have values of x which are -3, -2, -1, 0, 1, 2, 3, the values of y would be:

x = - 3:
= x + 1

= - 3 + 1

= -2

x = - 2

= - 2 + 1

= - 1

x = - 1

= - 1 + 1

= 0

x = 0:

= 0 + 1

= 1

x = 1 :

= 1 + 1

= 2

x = 2 :

= 2 + 1

= 3

x = 3 :

= 3 + 1

= 4

The points would then be:
( - 3, - 2) , ( - 2, - 1) , ( - 1 , 0 ) ( 0, 1 ) ( 1, 2 ) ( 2, 3 ) ( 3, 4 )

The zeros of f(x) = 4x³ + 4x² -37x + 44, using the Factor Theorem, are given as follows:

x = -4, x = 1.5 + 0.707i and x = 1.5 - 0.707i.

The function for this problem is defined as follows:

f(x) = 4x³ + 4x² -37x + 44.

The first linear factor is given as follows:

x + 4 = 0

x = -4 is the first zero.

The Factor Theorem states that the polynomial can be written as a product of it's linear factors.

x + 4 is of the first degree, while the polynomial is of the third degree, hence the remaining linear factors form a second degree polynomial, thus:

(x + 4)(ax² + bx + c) = 4x³ + 4x² -37x + 44.

Then, multiplying on the left side, we have that:

ax³ + (4a + b)x² + (4b + c)x + 4c = 4x³ + 4x² -37x + 44.

Then the coefficients are given as follows:

Inserting these coefficients into a quadratic function calculator, the remaining zeros are given as follows:

x = 1.5 + 0.707i, x = 1.5 - 0.707i.

The factorization of the expressions gives 2(l + w), -2ab(b + 2a), (3x+2)(3x−2) and 3(x²+2x−6)

Factorization, also known as factoring, is the process of breaking a mathematical expression down into its individual factors. In algebra, factorization refers to the process of expressing a polynomial as a product of simpler polynomials, known as its factors.

To factorize an expression, you need to look for factors of that expression. That is:

1. 2l+2w

2l+2w = 2(l + w)

2. -2ab²-4a²b

-2ab²-4a²b = -2ab(b + 2a)

3. 9x²-4

9x²-4 = (3x+2)(3x−2)

4. y²+7x+12

This cannot be factorized

Answer:

Step-by-step explanation:

The solutions to the equation −2x+2=(1/3)^x+1 can be found by finding the values of x that make the two sides of the equation equal. To solve this equation, we need to find the x values where the graphs of f(x) and g(x) intersect.Since the two functions are not linear and have different forms, it's hard to find the exact solutions. One way to find the solution is to graph the functions and find the x values where the two graphs intersect.It's not possible to find the exact values of x that make the two sides of the equation equal, because the two functions don't intersect at any specific point. It's not possible to find an exact solution to this equation, so none of the options are correct.

Answer:

A G.P is a sequence of numbers such that the ratio of any two consecutive terms is a constant, called the common ratio. Given the first term (3) and the common ratio (0.25) of the G.P, we can find the sum of the first 5 terms using the formula:

S_n = a(1 - r^n) / (1 - r)

Where:

S_n is the sum of the first n terms of the G.P.

a is the first term of the G.P.

r is the common ratio of the G.P.

n is the number of terms in the sum.

So, to find the sum of the first 5 terms of the G.P, we can substitute the given values into the formula:

S_5 = 3(1 - (0.25)^5) / (1 - 0.25)

S_5 = 3(1 - (0.25)^5) / (1 - 0.25) = 3(1 - 0.25^5) / (1 - 0.25) = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75

S_5 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75

S_5 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.
