Answer:
a^n=-9+(n-1).5
Step-by-step explanation:
Arithmetic sequence=a+(n-1)d
a=-9
n=?
d=+5
Arithmetic sequence=-9+(n-1)5
=-9+5n-5
Collect like terms
-9-5+5n
-14+5n
So the final answer is
an=-9+(n-1).5
<h3>
6/11 = y/3</h3>
<em>Multiply both sides by 3.</em>
<h3>6/11 × 3 = y</h3>
<em>Express 6/11 × 3 as a single fraction.</em>
<h3>6 × 3/ 11 = y</h3>
<em>Multiply 6 and 3 to get 18.</em>
<h3>18/11 = y</h3>
<em>Swap the sides so that all the terms of the variables are on the left side.</em>
<h3>y = 18/11</h3>
Answer:
1
Step-by-step explanation:
4^3 × 4^-3
Apply the law of exponents.
4^(3+-3)
4^(0)
Any base with the exponent of 0 is equal to 1.
= 1
Just use the distance formula.. (-3 - -4)squared + (-5 - 6)squared
