N= -1
then 10- 6.2x-1=16.2
Answer:
x = 0 .
-20/19 (see below).
Step-by-step explanation:
√(x + 1) + √5x = √(7x + 1)
Squaring both sides:
x + 1 + 5x + 2√(x + 1)√5x = 7x + 1
2√(x + 1)√5x = 7x +1 - 1 - x - 5x = x
Squaring both sides:
4(x + 1)(5x) = x^2
20x^2 + 20x - x^2 = 0
19x^2 + 20x) = 0
x(19x + 20) = 0
x = 0, -20/19.
If we substitute x = 0 into the original equation we get
√(0 + 1) + √5*0 = √(7*0 + 1)
1 = 1 so this is a true solution.
-20/19 :- √(-20/19 + 1) is not real so unless we allow complex square root this is extraneous.
Answer:
C is the answer
g(x) = x² - 10 x + 29
Step-by-step explanation:
g(x) = (x -5)² + 4
= x² - 10 x +25 +4
= x² - 10 x + 29
∴ g(x) = x² - 10 x + 29
<span>N = number that must be inserted in the given numbers
to be divisible by 6
=> 3n
=> 85n
Now, let’s find a best number that will multiplied with both given number and
is divisible with 6.
=> 85n / 6
=> 85(6) / 6
=> 510 / 6
=>n = 6
now, let’s try to 3
=> 3(6) / 6
=> 18 / 6
=> 3
Thus, the value of N is 6 because it is divisible by 6 when multiplied to the
given number.
