A plane takes off from a runway given as the path with points A and B. Find the midpoint if point A is at (-1, 2) and point B is at (-2, -4)

(-1.5, -1)

Step-by-step explanation:

Here, you would essentially find the respective means of the x and y coordinates.

For x:

(-1 + (-2)) = -3

= -1.5

For y:

(-4 + 2) = -2

= -1

Thus, the midpoint would be (-1.5, -1)

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
