Answer: 132 degrees
Explanation: a straight line has 180 degrees in it, take away the 48 leaves you with 132.
so first you need to find the slop between (1,3) and (4,5)
5-3/ 4-1 = 2/ 3= m
using that slope you put it into the slope intercept formula
y=mx+b
use the coordinate (2,-5)
-5= 2/3 (2)+b
-5= 1.33+b subtract 1.33 on both sides
-6.33=b
plug b and m into the slope intercept formula
ANSWER: y=2/3x-6.33
Answer:
x=5
Step-by-step explanation:
We want the x value when the output is 3
This occurs at -7 and at 5
We want the x value other than -7 so x=5
<u>Understanding:</u>
The sum of a geometric series is, 
, with a being the start point and r is the common ratio. We can also use the following formula to make life easier 
, a is your start point, r is the common ratio, and n is the number of terms, which in our case is S7.
<u>Solution:</u>
Our start point is 1, 
,
The common ratio is 5, 
,
And finally, the number of terms is 7, 
.
The answer is [A] 19531.
