Step-by-step explanation:
Pretty sure it's A. It should be the answer
I think you forgot to include that T is the midpoint of SV, but what this would mean is that ST = TV.
5x + 2 = 3x + 12
Subtract 2 from both sides.
5x = 3x + 10
Subtract 3x from both sides.
2x = 10
Divide both sides by 2.
x = 5
Now plug that x into ST.
ST = 5(5) + 2
ST = 25 + 2
ST = 27
Answer:
C
Step-by-step explanation:
Since the y-int. is 2 we know that the coefficient of the exponential term is 2, which eliminates B and D. Since f(x) <em>decreases</em><em> </em>from left to right, the number in the parentheses has to be less than 1, so the answer is f(x) = 2 * (0.25)^x.
