Answer:

see below

Step-by-step explanation:

1. 2m = 24

Divide each side by 2

2m/2 = 24/2

m = 12

2. y – 9 = 30

Add 9 to each side

y-9+9 = 30+9

y = 39

3. X/4 = 12

Multiply each side by 4

x/4*4 = 12*4

x = 48

4. k + 12.5 = 30

Subtract 12.5 from each side

k+12.5-12.5 = 30-12.5

k =17.5

5. 3r = 15.3

Divide by 3

3r/3 = 15.3/3

r =5.1

lana [24]

Answer:

first option

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

m(x) = - 2 (x - 6)² + 18 ← is in vertex form

with vertex = (6, 18 )
