There are 40 houses in a neighborhood. Company X provides electricity to LaTeX: \frac{1}{8}1 8 of the houses.
Company Y provides electricity to LaTeX: \frac{2}{5}2 5 of the houses.
Company Z provided electricity to the remaining houses.
In this neighborhood, Company Z provides electricity to ---

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
