M = (y2 - y1) / (x2 - x1)
1/4 = (5-3) / (r +4)
1/4 = 2/ (r + 4)
Cross multiply
2*4 = r + 4
8 = r + 4
Subtract 4 from both sides
4 = r
CHECK
(-4,3)(4,5)
m = (5-3)/(4--4) = 2/8 = 1/4
Answer:
The number of tiles are covered by the painting are 12.
Step-by-step explanation:
Consider the provided information.
The painting is covering up some of the tiles on the wall as shown below:
Here it is given that there are 28 squares tiles on the wall.
Total tiles = Number of tiles covered by the painting - uncovered tiles
28 = Number of tiles covered by the painting - 16
Number of tiles covered by the painting = 28 - 16
Number of tiles covered by the painting = 12
Hence, the number of tiles are covered by the painting are 12.
About 4 days if you round
Subtract 4/5 from both sides. X = 10 1/5
