Answer:
H= 121.25 meters
Step-by-step explanation:
To find the value of H after 30 months given the equation H=0.20x+115.25,
replace x by 30 in the equation and solve;
H=(0.20*30)+115.25
H=6+115.25
H= 121.25 meters
Therefore, the height will be 121.25 meters
Answer:
60
Step-by-step explanation:
Answer:
She arrives at 4:30
Step-by-step explanation:
60/4= 15
15+15=30
4:30
Solve the second equation for y
x+2y = -8
x+2y-x = -8-x
2y = -x-8
2y/2 = -x/2 -8/2
y = (-1/2)x - 4
The slope here is -1/2, which is the same slope as the first equation. Because of this fact and the fact that the y intercept is not the same, we have two parallel lines. The parallel lines never cross.
There are no solutions
