Answer:
Step-by-step explanation:
x^2-8x+x-8
x(x-8)+1(x-8)
(x+1)(x-8)
The negative number is x=-1
No, the order does not matter.
Sometimes, depending on the question being asked there can be an order that is easier to use (for example if the plane is represented in a drawing it can sometimes be nice to name the points from left to right or top to bottom as they appear in the drawing, or you might like to name the points alphabetically) but this is NOT required and is not "more correct" than any other order.
Answer:
x = -1
Step-by-step explanation:
-Subtract 1 from both sides of the equation
x + 1 = 0
x + 1 - 1 = 0 - 1
-simplify
x = -1
<u>Solve for x:</u>
Add 4.3x on both sides so that the variable can be on one side.
9.6x - 15.4 = -4.3x + 26.3
+4.3x +4.3x
Add 15.4 on both sides so that the whole number stays on one side separate from the variable.
13.9x - 15.4 = 26.3
+15.4 +15.4
Divide both sides by 13.9.
13.9x = 41.7
------- -----
13.9 13.9
Now you get a solution of:
x = 3
<u>Check:</u>
9.6(3) - 15.4 = -4.3(3) + 26.3
28.8 - 15.4 = -12.9 + 26.3
13.4 = 13.4
Answer:
$119,422.9
Step-by-step explanation:
We can use the following formula to solve:
<em>P = principal value
</em>
<em>r = rate (decimal)
</em>
<em>t = time (years)</em>
<em />
First, lets change 6.75% into a decimal:
6.75% -> -> 0.0675
Now, plug the values into the equation:
The value of the car after 9 years will be $119,422.9
