Answer:

Image = (-1, -2)

Step-by-step explanation:

The rule of rotation of an object 90 degree is given by:

(x, y) \rightarrow (-y, x)

Given that:

If P(-2, 1) is rotated 90°

We have to find its image.

Apply the rule on P.

we have;

P(-2, 1) \rightarrow P'(-1, -2)

Therefore, its image is, (-1, -2)

yuradex [85]

Answer:

W = 16 in

Step-by-step explanation:

P = 2L + 2W

56 = 2(12) + 2W

56 = 24 + 2W

56-24 = 2W

32 = 2W

W = 32/2

W = 16 in

the taxi charges in a city consist of a fixed charge together with the charge for the distance covered. For a distance of 10 km,
Olegator [25]

Answer:

255

Step-by-step explanation:

total cost paid = fixed cost + total variable cost

total variable cost = distance travelled x variable cost per unit

two equations can be derived from the question

a + 10b = 105  equation 1

a + 15b = 155   equation 2

a = fixed cost

b =  variable cost per unit

Subtract equation 1 from 2

5b = 50

b = 10

Substitute for b in equation 1

a + 10(10) = 105

a = 105 - 100 = 5

a = 5

cost of travelling a distance of 25km

5 + 10(25) = 255
