Answer:
w < 7
Step-by-step explanation:
Since the inequality is an OPEN circle, that means the sign is < or >
Since the sign is going to the left that means it's < or ≤
The one that has both of these effects is <
Since the sign starts at 7, the inequality is w < 7

Answer:
43.
Step-by-step explanation:
2 negatives make a positive so:
35 - (-8) = 35 + 8 = 43
y = - 4
collect terms in x
xy + 4x = 1 - 20 = - 19 ( factor out x )
x(y + 4 ) = - 19 ( divide both sides by ( y + 4) )
x = ![\frac{-19}{y + 4}](https://tex.z-dn.net/?f=%5Cfrac%7B-19%7D%7By%20%2B%204%7D)
x will be undefined if the denominator of the fraction is zero
y + 4 = 0 ⇒ y = - 4
x has no solution for y = - 4
