Answer:
(c) x = 10
Step-by-step explanation:
The diagonals of a square cross at right angles, so the measure of angle KNJ is 90°.
90 = 10x -10
100 = 10x . . . . . add 10
10 = x . . . . . . . . divide by 10
The value of x is 10.
Answer:
8
Step-by-step explanation:
- (-2) is the same as + 2
-10 + 2 = -8
The statement is contradictory, because it is said that every member of the family gives a gift to every other member of the family. And from 10 members, there are just 2 exchanging. Anyway, maybe they are only 2 members exchanging the gifts at that point in time.
So, each member will exchange 9 gifts (that is 10 members total minus herself), and 2 members are exchanging gifts at that point, so 18 gifts are being exchanged.
Answer:
<em>y = - </em><em> x + </em><em> </em>
Step-by-step explanation:
(6, 4)
(1, 8)
m = = -
y - 4 = - ( x - 6 )
<em>y = - </em><em> x + </em> ⇔ y = - 0.8x + 8.8
