In one day, Mr. Stevens painted 1/5 of a house.
Each son paints 1/4.5 of a house in one day.
If Mr. Stevens and his two sons work together, the would paint (1/5+1/4.5+1.4.5)=(9/45+10/45+10/45)=29/45 of a house in one day.
It will take them 1/(29/45)=45/29 days to finish painting the house, assuming their work is additive, like no waiting for drying for the second coat, etc.
Answer: 
The distance between the coordinates of the two points is measured by the Distance formula
Step-by-step explanation:
The distance between two points P(x1,y1) and Q(x2,y2) is measured by Distance formula i.e Distance=
(x2-x1)²+(y2-y1)²
So, the distance between the two points P(5,-3) and Q(2,4) can be measured by
Distance PQ =
(2-5)²+(4-(-3))²
PQ =
(-3)²+7²
PQ=
9+49
PQ=
58
So,the distance of PQ is 
Answer:
b
Step-by-step explanation:
If you put it in slope intercept form, you will have:

.
If you converted the format, you could also have:

.
The rest of the choices are a different graph.
