Answer:
Step-by-step explanation:
5)
DG= 60 (whole)
DO= 4x-3 (Part)
OG= 2x+ 21 (Part)
4x-3+ 2x+21= 60
6x+18=60
6x=42
x=7
Using this we can solve for DO and DG
DO= 4*7-3
DO= 25
DG= 2*7+21
DG= 14+ 21= 35
6)
TB is whole
TU is part
UB is part
5x= 4x-1+2x-1
5x=6x-2
x=2
UB= 2*2-1= 4-1= 3
TU= 4*2-1= 8-1= 7
Answer:
2.2 seconds.
Step-by-step explanation:
We have been given that an astronaut on the moon drops a tool from the door of the landing ship. The quadratic function 
models the height of the tool, in meters, after x seconds.
To find the time, it will take for the tool to hit the surface of moon, we will set 
and solve for x as:
Divide both sides by negative 2:
Now, we will take square root of both sides:
Since time cannot be negative therefore, it will take 2.2 seconds for the tool to hit the surface of the moon.
Slope:
(2,2) (1,-3)
Answer:
(-2,1)
Step-by-step explanation:
Answer:
The end equation you get is p = 6x - 8
Step-by-step explanation:
p = 2l + 2w
p = 2(x + 5) + 2(2x - 9)
p = 2x + 10 + 4x - 18
p = 6x - 8
Answer:
y = -1/2x + -3
