Answer:
x=1
Step-by-step explanation:
3x - 5 =7x -9
Subtract 3x from each side
3x - 5-3x =7x-3x -9
-5 = 4x-9
Add 9 to each side
-5+9 = 4x-9+9
4 = 4x
Divide each side by 4
4/4 = 4x/4
1=x
Answer:
x = 1
Step-by-step explanation:
Using the rule of logarithms
b = 1
That is the logarithm of a number to the same base is 1
Given
5 = x , hence x = 1
The answer is C) y = 4x - 3
B and D can be eliminated by substituting 0 for x in each...the result is not -3
Now you have a 50/50 chance of getting the question correct
Answer:
x = -11/2
Step-by-step explanation:
The ratios need to stay the same
5x 11
----- = -------
x-2 3
Using cross products
5x*3 = (x-2) 11
15x = 11x - 22
Subtract 11 from each side
15x-11x = -22
4x = -22
x = -22/4
x = -11/2
