Answer:
-2
Step-by-step explanation:
Convert the words into a math equation
8n -3 = -19
If you multiply 8 by -2 you get -16
-16 - 3 = -19
Answer:
A=80t+500 B=30t+700
820 Students
Step-by-step explanation:
80t+500=30t+700
-30t -30t
50t+500=700
-500 -500
50t=200
/50 /50
T=4
A=80(4)+500=820
B=30(4)+700=820
Answer:
x-intercepts: (-3,0) and (4,0)
y-intercept: (0,1)
Step-by-step explanation:
Viewing the graph can tell you where each of the x and y-intercepts are. Simply viewing where the line crosses (and which axis is crossing) determines if it is a x-intercept or y. Look at coordinate (-3,0) to see the line crossing through the x-axis on the coordinate.

Answer:
The final position is 5 feet below the back of the truck
Step-by-step explanation:
* Lets explain how to solve the problem
- A crane lifts a pallet of concrete blocks 8 feet from the back of
a truck
- The crane lowers the pallet 13 feet after the truck drives away
- Assume that the zero level of the position of the ballet of concrete
blocks is the back of the truck
∵ The crane lifts the pallet of concrete blocks 8 feet from the back
of the truck
- That means it take the pallet from zero to 8
∴ The height of the pallet of concrete blocks is 8 feet over
the starting position
∵ The crane lowers the pallet of concrete blocks 13 feet
- That means the crane lower the pallet from the height 8 and
lift it down 13 feet, so we must to take out from the 8 feet the
13 feet to find the final position of the pallet of concrete blocks
∴ The pallet position is ⇒ 8 - 13 = -5
∴ The position of the pallet of concrete blocks is 5 feet below the
starting position which is the back of the truck
* The final position is 5 feet below the back of the truck
