Answer:
neither
Step-by-step explanation:
First, arrange the equations to fit the y=mx + b format
1. 2x - 3y = 8
y = -2/3x - 8/3
2. -x + 4y = 2
y = 1/4x + 1/2
Equations that are parallel have the same slope.
In perpendicular equations, one slope would be x and the other would be -1/x (negative reciprocal)
The equations are neither parallel nor perpendicular, so neither.
I'm pretty sure you already solved this by now, but I'll say the answer anyway. This problem has already been solved by another as a verified answer.
This is the concept of financial algebra, we are required to calculate the value of stock ABC which follows the model given by:
y=12.21x+37.42
given that x=62 days,
the value of th estock after 62 days will be given by:
y=12.21(62)+37.42
y=757.02+37.42
y=794.44
ABC will be worth $794.44
I take no credit for this answer. It was solved by CastleRook.
Answer:
For t=3 sec the velocity change from positive to negative
Step-by-step explanation:
we have

This is the equation of a vertical parabola open downward (the leading coefficient is negative)
where
s(t) is the distance in feet
t is the time in seconds
We know that
To find out when the velocity change from positive to negative, we need to determine the turning point of the quadratic equation
The turning point of the quadratic equation is the vertex
so
Convert the quadratic equation into vertex form

Factor -16

Complete the square


Rewrite as perfect squares

The vertex is the point (3,244)
therefore
For t=3 sec the velocity change from positive to negative
Answer:
the third choice
Step-by-step explanation:
I haven't done those questions in a long time so I would double check. But I think its choice C because 0 has two functions, and I'm pretty sure that a number can only have 1 output, therefore C is not a function..
