Answer:
Concept: Modeling expressions
- We are given the equation

- We want to find the time after 0.75 seconds given that t is represented in seconds.
- Hence we do

- Hence we get the answer to 191 feet
Answer:
no
Step-by-step explanation:
for the equation y=x^2 -6 the line is curved and both points are facing up. A linear pair has to be straight. Therefore, this equation isn't linear
Answer:
B. y=3(x-1)2 + 3
Step-by-step explanation:
Given that
vertex of the parabola is at the point (1,3)
let's verify, if the option B is the correct equation of the parabola.

comparing to standard equationof parabola (standard quadratic equation), we get

to find the vertex we use formula for x- coordinate as 

to find y put x=1 in the Eq1, we get

vertex =(x,y) = (1, 3)
thus vertex of the parabola from the equation y=3(x-1)2 + 3 is (1,3), thus verified
6x - 4 < 8
Add 4 to both sides:
6x < 12
Divide both sides by 6:
x < 2
Answer: x < 2
184 = ¹/₂x(8.5 + 14.5)
184 = ¹/₂(23)
<u>184</u> = <u>11¹/₂x
</u>11¹/₂ 11¹/₂
16 = x
