If she can only work 15 hours a week and earns $7 per hour, just multiply 7 by 15 and you'll have your answer :)
3x - 2y = 13
-2y = -3x + 13
y = 3/2x - 13/2...slope is 3/2, y int is -13/2
2x + 3y = -16
3y = -2x - 16
y = -2/3x - 16/3...slope = -2/3, y int is -16/3
perpendicular lines will have negative reciprocal slopes. To find the negative reciprocal of a number, flip the number and change the sign.
On the 1st equation, the slope was 3/2....find its negative reciprocal.....flip it, making it 2/3....change the sign...making it -2/3. So the negative reciprocal of 3/2 is -2/3.
So if one equation has a slope of 3/2 and another equation has a slope of -2/3, then these lines are perpendicular <==

Split the second term in 3m^2 + 5 - 8m into two terms
3m^2 - 3m - 5m + 5
Factor out the common terms in the first two terms, then in the last two terms.
3m(m - 1) - 5(m - 1)
Factor out the common term m - 1
<u>(m - 1)(3m - 5)</u>
