Answer:
B. It's actually something like 2.142857143... but you know, the closest answer is 2.14.
12. The inverse relation has the x- and y-values swapped.
The appropriate choice is ...
D. (13, 5)
Answer:
see explanation
Step-by-step explanation:
step 4 take the square root of both sides
= ± 
x + 4 = ± 
step 5 subtract 4 from both sides
x = - 4 ± 
step 6 solve for x
x = - 4 -
or x = - 4 + 
Steps:
1. Do a proportion
8000 pounds/4 tons= 7000 pounds/ x
2. Do 7,000 times 4 which equals 28,000
3. Do 28,000 divided by 8,000
4. Your answer is
3.5 tons
