Answer:
y = -3/7x + 5
Step-by-step explanation:
y2 - y1 / x2 - x1
2 - 8 / 7 - (-7)
-6/14
= -3/7
y = -3/7x + b
2 = -3/7(7) + b
2 = -3 + b
5 = b
Answer:
C
Step-by-step explanation:
Using the pythagorean theorem, we can determine if these are right triangles or not.
equation: sqrt a^2+b^2=c
this means the square root of the two shortest sides squared must equal to the largest side, (the hypotenuese).
Work for C:
Squareroot of 32^2 + 24^2 = 40cm
Step-by-step explanation:
Tile A $9.75
Tile BTiles are $11 per tile if fewer than 50 tiles are purchased. For 50 or more tiles, tiles are $9.50 per tile.
Tiles are purchased by the box
Tile C There are 24 tiles per box. Each box is $185.
Answer: x = 32
Step-by-step explanation:
x/8 - 5 = -1
Add 5 both sides : x/8 = 4
Multiply both sides by four: x=4 times 8
