B because every x-value corresponds to exactly one y value.
The final solution is X=4i , -4i, -5i, 5 Hope this helps:)
Her niece sees 15 goats.
Step-by-step explanation:
Given,
Total animals on barn = 40
Total legs counted by May's niece = 110
A goat has 4 legs and chicken has 2 legs.
Let,
x represent the number of goats
y represent the number of chicken
x+y=40 Eqn 1
4x+2y=110 Eqn 2
Multiplying Eqn 1 by 4
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 2
Putting y = 25 in Eqn 1
Her niece sees 15 goats.

Answer:
42 + 42 + z = 180
Step-by-step explanation:
Note that:
Base angles in an isosceles triangle are equal in measure.
The sum of angles in a triangle is 180°.
Thus, the equation would be
42 + 42 + z = 180
