5/6 because she already picked a blue tile. it makes the grey tile to be picked.
Answer:
Step-by-step explanation:
A (1 ,7) , B(4, 2), C(-1, -1) and D(-4, 4)
Find the distance of sides using distance formula.
Distance = 
A (1 ,7) , B(4, 2)

AB = BC = CD = AD = √34 units. so , ABCD is a square.
Area of square = side * side
= √34 * √34
= 34 square units
The correct answer is d. Solid line with shading on the side that includes the origin
We can tell this for two reasons. Firstly, since it is "greater than or equal to" we use a solid line. If it were just "greater than" than we would have used a dotted line.
Secondly, to tell if the origin should be shaded is by plugging in (0,0) and seeing if it is a true statement. If it is true, it is shaded.
5x + y ≥ -10
5(0) + 0 ≥ -10
0 + 0 ≥ -10
0 ≥ -10 (TRUE)
Answer:
Four equivalent ratios:
1) 5:15
2)1:3
3) 10:30
4) 20:60
