I'm assuming you mean Cartesian plane. It is the same as a coordinate plane. There are two perpendicular lines with an x (horizontal) and y (vertical) axis.
Answer:
20hours
Step-by-step explanation:
Jack can complete the painting in 30hours. The fraction he can paint per hour is thus 1/30
Trainee can complete the painting in 45hours, the fraction he can paint per hour is 1/45
If they are working together, the fraction that can paint in an hour is :
1/45 + 1/30 = 5/90 = 1/18
Now we know they can paint 1/18 of the room in an hour, the number of hours needed to completely paint the room is thus 1/1/18 = 18 hours
Rounding up answer to the nearest tenth is 20hours
I think that induction is based on making conclusions based on previous examples such as "3,5,7 are primes, so every odd integer. Deduction it's based on logical reasoning other than examples
Answer:
5
Step-by-step explanation:
Answer:
Y' (5, -3), Z' (3, -2)
Step-by-step explanation:
The translation is right 4 and down 1. Since you are going from (3, -4) to (7, -5), to get from 3 to 7 on the x axis you move right 4. To get from -4 to -5 on the y axis, you go down 1.
Y (1, -2) add 4 to the x value. 1 + 4 = 5. Add -1 to the y value. -2 + -1 = -3. Y' (5, -3)
Z (-1, -1). Add 4 to the x value. 4 + (-1) = 3. Add -1 to the y value. -1 + (-1) = -2.
