Similar shapes :-
first convert everything to inches 6 feet = 72 inches
5 / 45 = x / 72
1/9 = x / 72
x = 72/9 = 8 inches answer
I believe the answer is: C. (2,-1)
I hope this helps!
Answer:
x = -3.5
Step-by-step explanation:
(By converting both sides to have the same bases, we can then evaluate the exponents. Substitute 27 with 
)
(Since the x is outside the parenthesis on the LHS, we can multiply the exponents)
(Now that the bases are equal, we can set the exponents equal to each other and then solve for them)
x - 7 = 3x (Subtract x from both sides)
-7 = 2x (Divide both sides by 2)
x = -3.5
Answer:
x=9
Step-by-step explanation:
3 ^ (x-4) = 243
Rewrite 243 as a power of 3
3 ^ (x-4) =3^5
Since the bases are the same, the exponents are the same
x-4 =5
Add 5 to each side
x-4+4 = 5+4
x=9
