It's given in the question,
- Bianca works as a content writer for $10 per hour.
- She works as a library assistant for $14 per hour.
She worked for a combined total of 75 hours for both the jobs this month.
Let c be the number of hours Bianca worked as a content writer.
Her earning for this month as a content writer = $10c
Her working hours as library assistant this month = (75 - c) hours
Therefore, her earning as a library assistant for the month = $14(75 - c)
By adding the earnings as a library assistant and a content writer for the month = $10c + $14(75 - c)
= (10c - 14c) + 1450
= $(9c + 1050)
Therefore, expression for the combined total amount she earned this month will be $(9c + 1050).

There will be no angle between the lines as the lines are parallel.
We are given the two lines:
2 x - 3 y + 5 = 0 and 2 x - 3 y - 7 = 0
Slope of the line 2 x - 3 y + 5 = 0:
-a₁/b₁ = -2/-3 = 2/3
Slope of the line 2 x - 3 y - 7 = 0
-a₂/b₂ = -2 / -3 = 2/3
Since both the lines have same slopes, they are parallel lines and will not intersect each other.
So, there will be no angle between the lines.
