The x and y values in the given matrices are 6 and 7 respectively.

Step-by-step explanation:

Step 1; Both the given matrices are of the order 1 × 2. So to solve the values of x and y is just a matter of substitution. We substitute the values which correspond with each other i.e we substitute the values of a_{11} which is the element at row 1 column 1 of both matrices. Similarly, the values of a_{12} in both matrices are substituted with each other.

Step 2; The value of a_{11} of the first matrix is 4x and the corresponding value in the second matrix is 24. So 4x will be equal to 24. Similarly, the value of a_{12} in the second matrix is 6y and its corresponding value in the first matrix is 42. So 6y will equal 42.

4x = 24, x = \frac{24}{4}, x = 6

6y = 42, y = \frac{42}{6}, y = 7

{x}^{2}   + 4x - 12 = 0 \\  {x}^{2}  + 4x + 4 - 4 - 12  = 0\\   {(x + 2)}^{2}  - 16 = 0 \\ x =   -   +  \sqrt{16}  - 2 \\ x =   + \:  or - 4 - 2 \\ x =  - 6 \:  \: x = 2
- subtract the 12 from both sides so that it becomes the last constant term in the quadratic equation which should now equal 0.
- take the 4x
- half the coefficient of 4 (2)
- square it (4)
- add it to the equation (+4)
- subtract it from the equation (-4)
- factorise the square (x+2)^2 expands to (x^2 + 4x + 2) as {a+b}^2={a^2 + ab + ba + b^2}
- now the equation is in turning point form.
- to find x, add 16 and square root 16 and (x+2)
- subtract 2 from positive or negative 4 (as -4^2 and 4^2 both equal 16).
- This should give you two values for x, -6 and 2.


I really hope that this helped :)

Since AB and BC are congruent, ABE is equivalent to CBE. ABE+CBE=ABC. So the answer would be 80 degrees.

What is the greatest common factor of 49, 62 and 80? OA) 1 OE) 2 OC) 3 OD) 5​
madam [21]

Answer: A (1)

Step-by-step explanation:

The way to find a common factor is by dividing the given numbers by the largest possible multiple that still gives you a whole number

A

49/1=49

62/1=62

80/1=80

This is an option

B

49/2=24.5

62/2=31

80/2=40

This is not an option, 24.5 is not a whole number

C

40/3=16.333(repeating)

This is not an option, you are not given a whole number

D

49/4=12.25

This is also not an option, 12.25 is not a whole number

Answer

Our only possible answer is A-1
