You can write it out multiple ways, such as x<=-4, x is (-infinity, -4], or {x | x<=4}. Even using a line, put -4 down, with a closed circle (including it means) and an arrow from there pointing left, for the included values to negative infinity.
Answer:
y = 5
Step-by-step explanation:
y = mx + b
5 = 6m + b
5 = 3m + b
Take the first minus twice the second.
-5 = - b
b = 5
Substitute back to calculate m.
5 = 6m + 5
6m = 0
m = 0
100÷ 86 equals 1.16 times 100 equals 116
