Answer: second option.

Step-by-step explanation:

Given the transformation T:(x,y)→(x-5,y+3)

 You must substitute the x-coordinate of the point A (which is x=2) and the y-coordinate of the point A (which is y=-1) into (x-5,y+3) to find the x-coordinate and the y-coordinate of the image of the point A.

Therefore, you get that the image of A(2,-1) is the following:

(x-5,y+3)=(2-5,-1+3)=(-3,2)

You can observe that this matches with the second option.

Find the value of two numbers is their sum is 21 and their difference is 3
kobusy [5.1K]

Hello from MrBillDoesMath

Answer:   12, 9

Discussion:

Let x be the first number and y the second number. The form the problem statement:

x + y = 21

x - y = 3


Add the two equations. This gives:

(x + x ) + ( y-y) = 21 + 3 =>

2x + 0 = 24 =>

x = 12

Since x -y =3, substituting in the value of x gives,  12 - y = 3 so y = 9


Thank you,

Mr. B

The check-cashing store also makes one-month add-on interest loans at 7.8 percent discount interest per week. Thus if you borrow
masya89 [10]

Answer:

APR = 416%

EAR = 5370.60%

Step-by-step explanation:

Given:

Interest rate = 7.8% per week

Now,

In an year there are total 52 weeks

thus,

The APR (Annual percentage rate) = Interest rate × Total weeks in an year

or

APR = 8% × 52

or

APR = 416%

and, EAR ( Effective Annual Rate ) = ( 1 + r )ⁿ - 1

Here,

r is the interest rate per week

n is the total weeks in an year

thus,

EAR ( Effective Annual Rate ) = ( 1 + 8% )⁵² - 1

= ( 1 + 0.08 )⁵² - 1

= 53.7060

or

53.7060 × 100% = 5370.60%

Answer:

12x^4-20x^2+32x=4x(3x^3-5x+8)

Step-by-step explanation:

<u>Common Factors</u>

An algebraic expression that is formed by sums or subtractions of terms can be factored provided there are numeric or variable common factors in all the terms.

The following expression

Z=12x^4-20x^2+32x

Can be factored in the constants and in the variable x.

1. To find the common factor of the variable, we must locate if the variable is present in all terms. If so, we take the common factor as the variable with an exponent which is the lowest of all the exponents found throughout the different terms. In this case, the lowest exponent is x (exponent 1).

2. To find the common factors of the constants, we take all the coefficients:

12 - 20 - 32

and find the greatest common divisor of them, i.e. the greatest number all the given numbers can be divided by. This number is 4, since 12/4=3, 20/4=5 and 32/4=8

3. The factored expression is

Z=12x^4-20x^2+32x=4x(3x^3-5x+8)

\boxed{12x^4-20x^2+32x=4x(3x^3-5x+8)}
