15. What is the algebraic notation of a figure is Translated 8 units left and 2 units up?

sasho [114]

Answer:

Please check the explanation.

Step-by-step explanation:

When a figure is translated with 8 units left and 2 units up, it means the translated figure can be obtained by subtracting 8 units from the x-axis and adding 2 units to the y-axis.

For example, if a point P(0, 0) is translated with 8 units left and 2 units up, the new position of the point will be:

(x, y) → (x-8, y+2)

P(0, 0) → P'(0-8, 0+2) = P'(-8, 2)

Thus, the new location of the image of point P will be: P'(-8, 2)

Therefore, option (a) is the correction answer.

FOR QUESTION 16

As the algebraic notation of a figure is Translated 2 units right and 5 units up.

Translating 'a' units right mean, we need to add 'a' units to the x-axis.

Thus, the rule will be:

(x, y) → (x+2, y+5)

Therefore, option (b) is correct.

Mnenie [13.5K]

Answer:

$3.75

Step-by-step explanation:

Given:

Natalie buys a cooper wire that is 3 feet long.

The cost of the wire is $1.25 per foot.

Question asked:

What is the total cost, in dollars, of Natalie's wire?

Solution:

By unitary method:

Total length of wire = 3 feet

Each foot of wire cost = $1.25

3 feet of wire cost = $1.25 $\times$ 3 = $3.75

Thus, total cost of wire is $3.75
