I think it's the answer C, because in the second and third pairs, the -2 are the same.
Answer:
She can create a function for the total savings in terms of the time x by adding the two functions together. The new function should look like this:
T(x)=S(x)+a(x)
So now we can substitute the given functions:
T(x)=450+6(x-2)
But this function can be simplified for it to be easier for her to calculate her total amount of savings. We can do that by distributing the 6 into the parenthesis. This is, multiply the 6 by both the x and the -2, so we get:
T(x)=450+6x-12
and now we can combine like terms. We can subtract 12 from 450 so we get:
T(x)=6x+438
And that will be our final function.
Answer:
116°F = 46.67 °C and 6 Pounds = 2721.55 grams
Step-by-step explanation:
The information given in the question is 1°F = -17.22°C
1 Kilogram = 1000 grams = 2.2 pounds
And we have to convert 116° F to degrees Celsius and Six pounds to grams.
1) We know (°F-32)×5/9 =°C
So by putting the value of °F as 116 ⇒ (116-32)×5÷9 = °C
⇒ °C = 
⇒ °C = 46.67
2). ∵ 2.2 Pounds = 1000 grams
∴1 Pound = 1000/2.2 = 454.54 grams
∴ 6 pounds = 6× 454.54 grams
= 2721.55 grams
