Answer:
below
Step-by-step explanation:
x: ticket
y: total cost
y= 10x + 8
y= 12x
3t+40=A
he starts with 40, so you add that to 3 t (3 meters every year-t)
Step-by-step explanation:
In the plane geometry Abeka, second edition, it is given :
Principle 2 states that between any two points, only one straight line can be drawn.
And according to principle 3 two straight lines interacts at one point only.
Thus this can be well illustrated by two straight lines which are represented by the streets of a city and these two streets intersects at a point.

Answer:
y = - 16t² + 55.6t + 6
Step-by-step explanation:
Using y - y₀ = vt - 1/2gt² where g = 32 ft/s², and v the velocity of the football
So y = y₀ + vt - 1/2 × (32 ft/s²)t²
y = y₀ + vt - 16t² where y₀ = 6.5 ft
y = 6 + vt - 16t²
Now, when t = 3.5 s, that is the time the teammate catches the ball after the quarterback throws it, y = 5 ft. Substituting these into the equation, we have
5 = 6.5 + v(3.5 s) - 16(3.5 s)²
5 = 6.5 + 3.5v - 196
collecting like terms, we have
5 - 6.5 + 196 = 3.5v
194.5 = 3.5v
v = 194.5/3.5 = 55.57 ft/s ≅ 55.6 ft/s
So, substituting v into y, our quadratic model is
y = 6 + 55.6t - 16t²
re-arranging, we have
y = - 16t² + 55.6t + 6
