The given pair of lines are not perpendicular.
<h3>What is a line?</h3>The line is a curve showing the shortest distance between 2 points.
5x - 5y = -2 - - - - - (1)
Transform the equation into standard form,
5x + 2 = 5y
y = 5x /5 + 2/5
y = x + 2/5
The slope of equation 1 is and intercept c = 2 / 5
Similarly
x + 2y = 4 - - - - - - - -(2)
Transform it into standard form
y = -x/2 + 4 /2
y = -x / 2 + 2
Slope of the equation 2 = -1 / 2 and intercept c = 2
Slope of line 1 * slope of line 2 = 1 * -1/2 = -1/2
Since the lines are not perpendicular because the pair of lines does not satisfy the property of perpendicular lines i.e
Thus, the given pair of lines are not perpendicular.

Answer:
Jena spends $ 733. 33 on her rent and groceries altogether per month.
Step-by-step explanation:
Jena's total income in a month= $1600
Here , expenditure on rent = (1/3) of her income
So, now one- third of her income $1600 is
=
or, (1/3) of her salary is $533. 33
Hence, Jena spends $ 533. 33 on her rent monthly.
Now, her expenditure on groceries = (1/8) of her income
So, now one- eighth of her income $1600 is
=
or, (1/8) of her salary is $ 200.
Jena spends $ 200. on her groceries monthly.
So, Total expenditure = Expenditure on rent + Expenditure on groceries
= $533. 33 + $200 = $733.33
Hence, Jena spends $ 733. 33 on her rent and groceries altogether per month.
