Answer:
492.99
Step-by-step explanation: x = amount invested at 12%
y = amount invested at 9%
---
x + y = 20287
0.12x = 0.09y + 492.99
---
put the system of linear equations into standard form
---
x + y = 20287
0.12x - 0.09y = 492.99
Answer:
y = -3x/4+3/2
Step-by-step explanation:
Step-by-step explanation:
y int is -9. to graph slope think a our rise/run. change in y / change in x. move 5 units up per 3 units right. it's a positive slope to the graph is increasing towards the right
Answer:
x=21
Step-by-step explanation:
4x+12=96
subtract 12 from both sides
4x=84
divide both sides by 4
x=21
