Answer: 7k^2+2k+10

Step-by-step explanation: To simplify this, you need to combine like terms, which are just the numbers that have the same variables and exponents. Combine 2k^2 and 5k^5 and it is 7k^2 (Just add the coefficient). Then do 3k -k, which is 2k. k just represents 1, so basically, 3-1. Finally, 7 + 3, which is 10. Then, combine the results to form an expression, which is 7k^2+2k+10.

There is 6 7/8 cups now i take 2 5/8 away how many is left ?

REY [17]

left means subtracting

6 7/8 - 2 5/8

Whole numbers subtract each other

Numerators subtract each other

The denominators stay the same.

6-2= 4

7-5=2

4 2/8

Reduce 2/8. Divide by 2. 2/2= 1, 8/2= 4

4 2/8=4 1/4

Answer: 4 2/8 = 4 1/4 cups left

Which is an exponential growth function f(x)=6(0.25)x<br> f(x)=0.25(5.25)x

Vikki [24]

Answer: Second Option

$f(x)=0.25(5.25)^x$

Step-by-step explanation:

The exponential growth functions have the following form:

$f(x) = a(b)^x$

Where a is the main coefficient, b is the base and x is the exponent.

For this type of functions the base b must always be greater than 1. Otherwise it would be an exponential decay function

Among the options given, the only function whose base is greater than 1 is the second option:

$f(x)=0.25(5.25)^x$
