PilotLPTM [1.2K]

Answer:

option A)  y > 5/4x + 10

Step-by-step explanation:

Take any point in the shaded region

( -12 , 1)

1 > 5*(-3) +10

1 > -15 + 10

1 > -5

A=future amount
P=present amount
r=rate in decimal
n=number of times per year compounded
t=time in years

Aleksandr [31]

Solution: \left(2x^2+4x-3\right)-\left(2x^2+4x-3\right)=0

Steps:

\mathrm{Remove\:parentheses}:\quad \left(a\right)=a, =2x^2+4x-3-\left(2x^2+4x-3\right)

-\left(2x^2+4x-3\right):\quad -2x^2-4x+3

=2x^2+4x-3-2x^2-4x+3

\mathrm{Simplify}\:2x^2+4x-3-2x^2-4x+3:\quad 0

=0
