Myra wants to save at least $500 by the end of her summer vacation. She currently has $350 saved. She can earn $25 cutting a law

Since this is an inequality we need more than just the equal sign, but it can help to create a linear equation to get it. we only need to define one variable since they give us one, so what i will use is M=total money earned
M=350+25N
now simply replace your equation sign with the less than or equal to sign (
) and the M with the 500 since Myra wants at least that.
500350+25N
now we must look for the least amount of times Myra needs to mow lawns, use the linear equation because exactly $500 is earned. this will be our M
500=350+25N
now take away 350 from each side so we can get N alone
150=25N
now divide each side to get N completely alone and that will give us the least amount of lawns Myra will need to mow to get to her goal
6=N, and since this was supposed to be an inequality replace the equal sign with the less than or equal to sign, 6N, or at least 6 lawns need to be mowed to get to Myra's goal
M=350+25N
now simply replace your equation sign with the less than or equal to sign (

<h3>Answer:</h3>
(1, 1), (4, -25)
<h3>Step-by-step explanation:</h3>You can evaluate the function to see.
f(-1) = -3^(-1-1)+2 = -3^(-2)+2 = -1/9 +2 ≠ 2
f(1) = -3^(1-1) +2 = -1 +2 = 1
f(0) = -3^(0-1) +2 = -1/3 +2 ≠ 0
f(4) = -3^(4 -1) +2 = -27 +2 = -25
