First, let's solve the inequality
2.9 (x+8) < 26.1
2.9x + 23.2 <26.1
2.9x < 26.1 -23.2
2.9x <2.9
dividing both sides by 2.9 we get:
x < 1
so, it is the last numberline graph, because it contains an empty circle at 1 on the numberline, which means it doesn't include 1. but all numbers less than 1
Test them
(x,y)
(2,4) and (3,3)
see if get true
(2,4)
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14=16
false
(3,3)
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6=15
false
neither
Answer:
y=9sin(theta)
Step-by-step explanation:
I'm assuming it's in degrees. The amplitude of the graph is 9, and so you multiply the base sine equation y=sin(theta) by nine. I don't see any shifts and the period remains at 2pi (360 degrees) so I don't think anything else is really needed.
Answer: y=3/5x-26/5 is the equation for this problem.
