LESSON: SYSTEM OF NONLINEAR EQUATIONS

SOLVE THE FOLLOWING SYSTEMS OF NONLINEAR EQUATIONS USING EITHER SUBSTITUTION OR ELIMINATION METHOD.

1.) x + y = 100

x + 7y = 50

2.) y - x = -10

4x + y = 100

3.) x - 6x = y - 4

y - 2x = -8

4.) 3x - 7y = 20

4x + 9y = 45

LESSON: SERIES

COMPUTE EACH SUM BY APPLYING PROPERTIES OF SUMMATION.

1.) 5

( 5i - 3 )

t = 1

2.) 5

( 4k + k )

k = 1

3.) 7

( -4 + 2i )

t = 1

4.) 8

( k + 5 )

k = 3
