Step-by-step explanation:

The equation given is of the form

y = a(x - h)^2 + k

where (h, k) are the coordinates of the vertex. So in this case, the vertex is located at (4, 2). Since a is a negative number (a = -3), this means that the vertex is a maximum because the parabola opens downward.

tigry1 [53]

Answer:

  68 texts per day

Step-by-step explanation:

The description of the variables in the equation tells you that you want to find t (texts sent per day) for the given value of 'a' (age in years).

__

Substitute the number (15) for the variable (a) and do the arithmetic:

  t = -1.63a +92.14

  t = -1.63(15) +92.14 = -24.45 +92.14

  t = 67.69

Keiko's trend line estimates a 15-year-old would send about 68 texts per day.

15 point help asap marking brainlest!!!!!!!!!!!!!!
ziro4ka [17]

slope =(y2-y1)/(x2-x1)

m=(-1-5)/(1--1)

m=-6/2

m=-3

y-y1=m(x-x1)  point slope form

y-5 = -3 (x--1)

y-5 = -3 (x+1)

distribute

y-5 = -3x -3

add 5 to each side

y = -3x+2

Choice D

A 16 kg bag of watermelon for $8 per kg
Zarrin [17]
To solve this all we need to do is multiply. 

Since 1 kg is for $8, then we will multiply to see how much 16 kg would be for.

16 × 8 = 128

So, 16 kg is for $128. 

Hope I helped ya!!!!
