Hello can you me ? ) answer question 3 and 7

3.

1h - $50

xh - x · $50

f(x) = 50x

x = 6 → f(6) = (50)(6) = 300

$300.

7.

1DVD - $17.75

xDVD - x · 17.75

f(x) = 17.75x

x = 5 → f(5) = (17.75)(5) = 88.75

$88.75

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

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.
