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
Answer:
10n - 3 = -13
Step-by-step explanation:
If y equaled 3, then we would plug 3 into the y spot on the equation. Therefore it would be 2x+4(3)=8. Now just solve.
2x+4(3)=8
2x+12=8
2x-12=8-12
2x=-4
2x/2=-4/2
X=-2
Hope this helped!

A = 6s²
a) s = 3in, subtitute
A = 6 · 3² = 6 · 9 = 54 (in²)
b) s = 1.5 m, subtitute
A = 6 · 1.5² = 6 · 2.25 = 13.5 (m²)
