Show that the credit card number
4306 0912 4887 1457 is valid/invalid.
Explain how you know.

Answers

Step 1a. For a card number with an even number of digits (e.g., Visa or MasterCard), double alternating digits starting with the first digit in the sequence.
Step 1b. For a card with an odd number of digits (e.g., American Express), double alternating digits starting with the second digit in the sequence.
Step 2. If the doubling resulted in a number with two digits, add them together to get a single digit number
Step 3. Now go back to the original credit number and replace the digits that you doubled with the new value — either the doubled value, or the doubled value with the digits added together — and add it all up.
Step 4. Check to see if the sum is evenly divisible by 10 (you can simply look to see whether or not it ends with a zero).
If the card number does not pass this check, then it is not a valid number. If, on the other hand, it does pass, then it may be a valid number with valid credit report.

There is a parallelogram ABCD with diagonals AC and BD. The diagonals AC and BD intersects each other at point E. Side AB is congruent to side CD. If ∠BAC ≅ ∠DCA, the Choose... theorem can be used to show that △ABE ≅ △CDE.

Answers

Answer:

SAS theorem

Step-by-step explanation:

Given

[tex]\square ABCD[/tex]

[tex]\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD[/tex]

[tex]\angle BAC = \angle DCA[/tex]

Required

Which theorem shows △ABE ≅ △CDE.

From the question, we understand that:

AC and BD intersects at E.

This implies that:

[tex]\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC[/tex]

and

[tex]\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED[/tex]

So, the congruent sides and angles of △ABE and △CDE are:

[tex]\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD[/tex] ---- S

[tex]\angle BAC = \angle DCA[/tex] ---- A

[tex]\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED[/tex] or [tex]\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC[/tex]  --- S

Hence, the theorem that compares both triangles is the SAS theorem

Write an equation that represents the line.
Use exact numbers.

Answers

Answer:

Step-by-step explanation:

it is hard to know exactly by eye balling the graph  I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it

the dots on the line are at (-2, -6) and (2, 3)  so we can find the slope m

in the y = mx + b line equation   b is the y intercept

m = Δy/Δx     =  (y1 - y2) / (x1 - x2)

                     =  (-6 - -3) /  (-2 - 2)

                     =     -3 / -4

                 m = 3/4

       y = 3x/4  +  y intercept     which i can't dissern (read directly from the

                                                  graph, but we believe y = 0   when x is six

       0 = 3(6)/4  + y intercept

       

       -18/4 = 18/4 -18/4  + y intercept

        -9/2 = y intercept

        -4.5 = y intercept

   y = 3x/4 - 9/2          i think exact number means NO FRACTIONS but that is whole number so let me gaggle it  What are exact numbers?  Gaggle indicates exact numbers are integers   example  3 ft in a yard 12 eggs in a dozen

    y = 3x/4 - 9/2               multiple both sides by 4

   4y = 3x  - 36/2

The length and width of a rectangle are 1/6 inches and 3/8 inches. What is the perimeter (in inches) of the rectangle?

Answers

Answer:

1 1/12inches

Step-by-step explanation:

Given

Length = 1/6 inches

Width = 3/8 inches

Perimeter of the rectangle = 2 (Length + Width)

substitute

P = 2(1/6 + 3/8)

P = 2(4+9/24)

P=  2(13/24)

P = 26/24

P = 1 2/24

P = 1 1/12inches

hence the perimeter of the triangle is 1 1/12inches

Two angles are vertical if one is 5x - 15 and the second angle is 3x + 1, what is the value of x



What is the measure of each angle

Answers

Answer:

Step-by-step explanation:

If they are vertical angles, they are opposite to each other where two lines intersect. Vertical angles are equal to each other so

5x-15=3x+1

2x-15=1

2x=16

x=8 degrees.

The angles are

a=5x-15, and x=8 so

a=5(8)-15

a=40-15

a=25 degrees.
