16. The open circle is excluded and closed is included.
x≤-6
x>2
17. The open circle is excluded so the inequality would be: -3<x<2
We have that
<span>(x-4)/(x+5)(x-1)
</span> the rational expression is equal to zero <span>whenever its numerator is zero
</span>x-4=0---------> x=4
the answer is x=4
Answer:
z = 
or z = 195.8
y=-30
a = 5
b = -7
x = 64
Step-by-step explanation:
Simplifying √196 before doing the multiplication:
( √196 ÷ 7 ) × √48
= ( (√4 × √49) ÷ 7 ) × √48
= ( (2 × 7) ÷ 7 ) × √48
= 2√48
Simplifying √48:
= 2 × √16 × √3
= 2 × 4 × √3
= 8√3
which is irrational because it's a square root
