Step-by-step explanation:
( y = 4x/5 + 2)
m1.m2 = -1
4/5.m2 = -1
m2 = -5/4
formula = y - y1 = m2 ( x - x1)
y - 3 = -5/4 ( x - 6)
y -3 = -5x /4 + 30/4
y = -5x /4 + 21/2
He only multiplied 6 by 5, and forgot the r to get 30+r=96. The correct solution is 30 + 6r = 96, or 6r=66. Divide both sides by 6 to get r = 11.

Answer:
<h2><u><em>
a = 17°</em></u></h2>
Step-by-step explanation:
it is a parallelogram, the opposite angles are the same size
so
4a + 64 = 8a - 4
64 + 4 = 4a
68 = 4a
a = 68 : 4
a = 17
<span>Checking the existence conditions for the multiplication of matrices, the following properties are valid:
1- associative: </span>
<span>
2- distributive in relation to addition: </span>
<span>
3- neutral element: </span>
, where
is the identity matrix of order
p.s:.
For the multiplication of matrices is not worth the commutative property.
Therefore:
Answer <span>B) It satisfies the associative and distributive properties, but not the commutative property.</span>
