Answer:
x = 4 is the solution
Step-by-step explanation:
given = x ( square both sides )
x + 12 = x² ( rearrange into standard form )
x² - x - 12 = 0 ← in standard form
(x - 4 )(x + 3 ) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
Insert these values into the original equation, and if both sides are equal, and those are the solutions.
x = 4 : = = 4 = x ← correct
x = - 3 : = = 3 ≠ - 3 ← false
the answer is x = 4
The graph is translates down 135 units, because you can see how the y-intercept decreased by 135 units from f(x) to g(x).
Answer:
71.2
Step-by-step explanation:
The area for a rectangle is width x height.
11393=160x
11393/160=x
71.2=x
Answer:
17
Step-by-step explanation:
b(n)=b(n-1)+1 means a term can be found by taking it's previous term and adding 1 to it.
So if b(1)=16, the next term b(2)=16+1=17.
