A1 Unit 3 Day 2

what is the variable that willl be "eliminated"?

5x - 4y = 11

5x + 4y = -14

• x variable

• y variables

• both variables

what is the resulting combined equation to the following system:

5x - 4y = 11

5x + 4y = -14

• 5x = -3

• 10y = -3

• 10x = -3

• 10x = -25

Solve using Elimination Method:

x - y = 11

2x + y = 19

• (10,-1)

• (-1,10)

• (3,-4)

• (6,7)

f(x)=4x+5
f(4)=

• 21
• -11
• -31
• 25

g(x) = 5 - 6x
Find g(-5)

• g(-5) = -25
• g(-5) = 6
• g(-5) = 4
• g(-5) = 35
