Answer:
B, D.
Explanation:
When graphed out it is a vertical line. A vertical line has an undefined slope.
The x intercepts the line at (-2,0).
Answer:
The value of x are all real number on x-axis the number that falls under x
example of the value of x are in this equation
y=2+5x
2x+6y=60
to find x
let make the first one equation 1 and the second equation 2
now, put equation 1 in equation 2
2x+6(2+5x)=92
open the by multiplying every thing in the bracket by 6
2x+12+30x=92
combine the like terms
2x+30x=69212
32x=80
now divide via by 32
32x/32=80/32
x=5/2

Answer:
X=1,5,4
Step-by-step explanation:
When the penny hits the ground, h will = 0.
So: Set h(t) = 0 = -4.9t^2 + 0t + 150 m
Then 4.9t^2 = 150, and so t^2 = sqrt(150 / 4.9) = plus or minus 5.53 sec.
We can use only the positive root, as we're measuring time.
t = 5.5 sec (answer)
