T(4,-1) means move 4 units to the right and 1 unit down.

Based on the image, M(-3,4) ; N(-2,1) ; P(-4,2)

So,
M:
-3 move 4 units to the right becomes 1 
4 move 1 unit down becomes 3
M'(1,3)

N
-2 move 4 units to the right becomes 2
1 move 1 unit down becomes 0
N"(2,0)

P
-4 move 4 units to the right becomes 0
2 move 1 unit down becomes 1
P''(0,1)

Answer:

3

Step-by-step explanation:

Here, rule T(4,-1) means every vertex of the triangle MNP moves 4 units in  the direction of positive x axis and 1 unit in direction of negative y axis.

After applying this rule the given triangle MNP  moves in the Cartesian plane  and a forms a new triangle (ΔM'N'P') which mention in the following way.

From the figure.

(1). The coordinate of point M is (-3,4) and it moves 4 units in the direction of positive x axis and 1 unit in the direction of negative y axis, then it form a new point M'(1,3).

(2). The coordinate of the point N is (-2, 1) and it moves 4 units in the direction of positive x axis and 1 unit in the direction of  negative y axis then, it form a new point N'(2,0).

(3). The coordinate of the point P is (-4,2) and it move 4 units in the direction of  positive x axis and 1 unit in the direction of negative y axis then, it form a new point P'(0,1)

Hence new ΔM'N'P' form which shown in the figure and y- coordinate of M (y -coordinate of M' in new Δ) is 3.

goblinko [34]
2 classes of 21 students each
21 × 2 classes = 42 students in total
42 × 3 mins = 126 minutes for 42 students
10 mins for 2 class pics = 20 minutes
126 + 20 = 146 minutes = 2 hours and 26 minutes

It should take 146 minutes (2 hours and 26 minutes) to take all the pictures.

Lily saved 16 coins. She saved ten-can and one-dollar coins only. If she had $5.20, how many ten-cent coins did she have?
Firlakuza [10]

Answer:

  12

Step-by-step explanation:

Let d represent the number of dimes Lily saved. Then the value of her coins in cents is ...

  10d +100(16-d) = 520

  -90d +1600 = 520 . . . . . eliminate parentheses, collect terms

  -90d = -1080 . . . . . . . . . . subtract 1600

  d = -1080/-90 = 12 . . . . . divide by the coefficient of d

Lily has 12 ten-cent coins.
