Equation; y=27x+405Step 1: Flip the equation.<span><span><span>27x</span>+405</span>=y</span>Step 2: Subtract 405 from both sides.<span><span><span><span>27x </span>+ 405 </span></span>= <span>y
<span> -405 −405</span></span></span><span><span>27x</span>=<span>y−405</span></span>Step 3: Divide everything by 27.<span><span><span><u>27x</u> </span></span>= <span><span><u>y − 405</u>
</span>27 27 27</span></span><span>--- dividing by 27 will isolate x which is the goal of solving the equation---

Answer:
a30 = 96
Step-by-step explanation:
-20,-16,-12,-8,-4
We are adding 4 each time, which is the common difference
-20+4 = -16
-16+4 =-12
The formula for an arithmetic sequence is
an = a1 +d(n-1) where a1 is the first term and 4 is the common difference
an = -20 +4(n-1)
We want the 30th term
a30 = -20+4(30-1)
a30 = -20 +4(29)
= -20 +116
= 96
