Answer:

81 mm

Step-by-step explanation:

mm's are smaller measurements than cm's, and as a result are more precise

1 cm = 10 mm

So 8 cm = 10 * 8 (mm)

= 80 mm

& 80 mm is smaller than 81 mm, so 81 mm is more precise

Hope this helps, and please mark me brainliest if it does!

If the trapezoid on the grid below is translated by using the rule (x,y)-> (x-4,y-3) what will be the coordinates of B’?

vesna_86 [32]

Answer:

B'(3, 5)

Step-by-step explanation:

Rule for the translation of a point (x, y) by 'h' units left and 'k' units upwards,

(x, y) → (x - h, y + k)

If h = 4 and k = 3,

$(x, y)\rightarrow(x-4,y+3)$

Following this rule coordinates of the image point of B will be,

B(7, 2) → B'(7 - 4, 2 + 3)

→ B'(3, 5)

Therefore, coordinates of the image point B' will be,

B'(3, 5)
