We have this equation:
First, combine both logarithms using the multiplication property and simplify the expression.
Now, use the definition of logarithm to transform the equation.
Finally, use the quadratic formula to solve the equation.
With this, we can say that the solution set is:
We cannot choose x = -100 as a solution because we cannot have a negative logarithm. The only solution is x = 1.
Answer: C) x = 7, y = -1
Step-by-Step Explanation:
=> y = -2x + 13 (Eq. 1)
=> 4x + 8y = 20 (Eq. 2)
Substitute value of ‘y’ from Eq. 1 in 2 :-
4x + 8y = 20
4x + 8(-2x + 13) = 20
4x + -16x + 104 = 20
-12x + 104 = 20
-12x = 20 - 104
-12x = -84
12x = 84
x = 84/12
=> x = 7
Substitute value of ‘x’ in Eq. 1 :-
y = -2x + 13
y = -2(7) + 13
y = -14 + 13
=> y = -1
Therefore, x = 7, y = -1 which can be written in an ordered pair as (7,-1).
Answer:
x = 37.8
y=39.6
Use similar triangles. These used to be tricky back in the day.
Step-by-step explanation:
Given sequence is: - 3, 5, 13...
Here first term a = - 3
common difference d= 5-(-3)=13-5=8
Hence, it is in A. P.
Nth term of an AP is given as:
