Answer:
x = 4
Step-by-step explanation:
You have to remember the "Quotient Rule" for exponent having same base.
The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.
Here,
base = 3
exponents = 2x + 1 , x + 5
3^(2x + 1) = 3^( x + 5)
3^(2x + 1) / 3^(x + 5) = 1
3^((2x + 1) - (x + 5) )= 1
3^(2x + 1 - x - 5) = 1
3^(2x - x +1 - 5) = 1
3^(x - 4) = 1
log 3^(x - 4) = log(1)
(x - 4) (log (3)) = 0
log(3) = 0 rejected
x - 4 = 0 accepted
x = 0 + 4
x = 4
Answer:
the irrational number is C. √3
Step-by-step explanation:
an irrational number is a number that cannot be written as a fraction
GIVEN: y = 3x + 5
--> slope of given line = 3
--> This means that your equation must have the same slope, or "m"
FORMULA OF A LINE: y = mx + b
--> Use point-slope form to find "b"
POINT SLOPE FORM: y - y₁ = m ( x - x₁ )
--> Plug in your given point AND the slope of the given line
y - 5 = 3 ( x - 4 )
y - 5 = 3x - 12
y = 3x - 7
