This week, I need you to put in some overtime, which will require you to work 15% longer than your normal 40 hours per work schedule. Then I should plan on working a total of how many hours this week?

46 hours

Step-by-step explanation:

15% of the normal working hours is;

× 40 = 6 hours

∴ 15% longer for this week will mean,

6 hours + 40 hours = 46 hours

so, plan on working a total of 46 hours this week

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5
