Find x & y so that quadrilateral is a parallelogram. (Look at image) please help!!

Mathematics
1 answer:
dybincka [34]3 years ago
4 0

Answer:

y = 2 and x = -3

Step-by-step explanation:

we know that opposite sides of a parallelogram are equal so

7y + 3 = 12y - 7

12y - 7y = 3 + 7

5y = 10

y = 10 / 5

y = 2

Now

-6x = -4x + 6

-6x + 4x = 6

-2x = 6

x = 6 / - 2

x = - 3

Hope it will help :)❤

Which equation demonstrates the multiplicative identity property
nignag [31]

<em>Equation b) (-3 + 5i) (1) = -3 + 5i  demonstrates the multiplicative identity property </em>

<h3>Further explanation</h3>

There are several properties in integer multiplication operations

  • 1. closed property

Multiplication between integers will produce integers too

  • 2. commutative property

a x b = b x a

  • 3. associative property

ax (bxc) = (axb) xc

  • 4. identity

ax1 = 1 x a = a

  • 5. distributive  property

* addition

ax (b + c) = axb + axc

* substraction

ax (b-c) = axb - axc

The Multiplicative Identity is <u><em>1 </em></u>

<u><em>The multiplicative identity property states that any number multiplied by 1 will produce an original number. </em></u>

We complete the answer choices available from the problem above:

a) (- 3 + 5i) + 0 = -3 + 5i

O is an identity in the sum operation, the statement is false

b) (-3 + 5i) (1) = -3 + 5i

1 is a Multiplicative Identity of multiplication, so the statement is true

c) (-3 + 5i) (-3 + 5i) = -16-30i

d) (-3 + 5i) (-3 + 5i) = 16 + 30i

choice c and is a multiplication factor, so the statement is false
