Step-by-step explanation:
So, the question is asking for the difference between -8 and 2.
-----------------------------------------------------------------------------------------------------------------
Explanation 1:
2 - (-8) = ?
2 + 8 = ?
10 = ?
-----------------------------------------------------------------------------------------------------------------
Explanation 2:
|2| - 0 = 2
|-8| - 0 = 8
2 + 8 = 10
Answer:
x = .06418
Step-by-step explanation:
2 + (9.2)−8x = 2.32
(9.2)−8x = 2.32 − 2
log (9.2)−8x = log .32
−8x log 9.2 = log .32
−8x log 9.2
−8 log 9.2
=
log .32
−8 log 9.2
x = .06418
1) The solution for m² - 5m - 14 = 0 are x=7 and x=-2.
2)The solution for b² - 4b + 4 = 0 is x=2.
<u>Step-by-step explanation</u>:
The general form of quadratic equation is ax²+bx+c = 0
where
- a is the coefficient of x².
- b is the coefficient of x.
- c is the constant term.
<u>To find the roots :</u>
- Sum of the roots = b
- Product of the roots = c
1) The given quadratic equation is m² - 5m - 14 = 0.
From the above equation, it can be determined that b = -5 and c = -14
The roots are -7 and 2.
- Sum of the roots = -7+2 = -5
- Product of the roots = -7
2 = -14
The solution is given by (x-7) (x+2) = 0.
Therefore, the solutions are x=7 and x= -2.
2) The given quadratic equation is b² - 4b + 4 = 0.
From the above equation, it can be determined that b = -4 and c = 4
The roots are -2 and -2.
- Sum of the roots = -2-2 = -4
- Product of the roots = -2
-2 = 4
The solution is given by (x-2) (x-2) = 0.
Therefore, the solution is x=2.
Answer:
$208.33
Step-by-step explanation:
Julie has to make the down payment which is 25% of $60000 after saving for 6 years.
Therefore, Julie has to save a total of
dollars.
And Julie has to save it for the duration of 6 years i.e. (6 × 12) = 72 months.
Hence, Julie has to save
dollars every month to make the down payment after 6 years. (Answer)
