By definition we have the meaning of FOIL is given by:
F: First
O: Outer
I: Inner
L: Last
We have then the following product:
Applying the FOIL method we have that the products are given by:
Answer:
the answer choice showing the FOIL method products is:
B. (X) (4x) + (2) (x) + (- 3) (4x) + (- 3) (2)
Answer:
Its 255+x=180 => so x=105
Answer:
1.
Step-by-step explanation:
The cell phone experiments an exponential depreciation, which is defined by the following formula:
, for . (1)
Where:
- Initial cost, measured in monetary units.
- Depreciation rate, no unit.
- Time, measured in years.
- Current value of the cell phone, measured in monetary units.
If we know that and , then the exponential decay function that represents the situation is:
Which means that correct answer is 1.
Expand
-5m + 45 = 27 - 7m
Subtract 27 from both sides
-5m + 45 - 27 = -7m
Simplify -5m + 45 - 27 to -5m + 18
-5m + 18 = -7m
Add 5m to both sides
18 = -7m + 5m
Simplify -7m + 5m to -2m
18 = -2m
Divide both sides by -2
-18/2 = m
Simplify 18/2 to 9
-9 = m
Switch sides
<u>m = -9</u>
(1/3)r + (2/3)r = -2 -1
1r = -3
r = -3
Hope this helps
