A college student has two different jobs. Her combined work schedules consist of no more than 48 hours in one week Which graph best represents the solution set for all possible combinations of the number of hours she worked at her first job, and y, the number of hours she worked at her
second job, in one week?
Answer

Choice A

Step-by-step explanation:

It's Choice A because it's the only one that kept the shaded area underneath the line, and the lines went up to only 48 hours for the first job and for the second job. Then all the possible solutions are in the shaded area.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
