7.5 pounds
Step-by-step explanation:
Since adding x grams of salt will bring th percentage of the salt to 25
Hence. 10% of the 50 gram gives. 5 gram initial salt before it is added.
5+ x/ 50 * 100= 25/
5+x /50 = 0.25
5+x = 12.5
X= 12.5- 5
X= 7.5pounds

Answer:
always true because 2x - x = x
Answer:
f(x)=1/4(4)^(x-1) -4
Step-by-step explanation:
The negative value for x=2 tells you that the vertical offset cannot be positive. That rules out the 1st and 3rd choices.
You can try x=2 in the remaining functions to see which works:
f(2) = 4(4^(2-1)) -4 = 12 ≠ -3 . . . . . . . . the 2nd choice does not work
f(2) = (1/4)(4^(2-1) -4 = -3 . . . . . . . . . . the 4th choice matches the table
