Answer:

The statement that best compares the rate of change for the two accounts is:

  • C) <u>John deposits $10 less each week than Mary</u>.

Step-by-step explanation:

In the equation that determines Mary's savings account balance:

  • y = $ 45x + $ 2800

It can be identified that the $ 2800 mentioned is the initial deposit with which the savings account was opened, so the value of $ 45 is the weekly moment that Mary saves week after week, which will be increased once the variable X increase, considering that John's weekly savings amount is $ 35, it is valid to state that John saves $ 10 less than Mary since:

  • $ 45 (amount saved by Mary) - $ 35 (Amount saved by John) = $ 10.

The answer is C.

John’s savings account equation would be y=35x + 2000 while Mary’s is y=45x + 2800.
By comparing them, we see that Mary deposits 10 more than John per week.

Answer:

Equivalent. 0.4(k+3)=0.4k+1.2

Step-by-step explanation:

x means multiplication. k is the variable.

Hi.

So, you have to distribute the 0.4 into the parenthesis to get rid of them. So, you do 0.4xk, which is just 0.4k, and 0.4x3, which is 1.2. So, you have 0.4k+1.2, which means it is Equivalent.

Answer:

\sqrt[7]{b^{15}}

Step-by-step explanation:

=> b^2*\sqrt[7]{b}

=> b^2*b^{1/7}

Where bases are same, powers are to be added.

=> b^{2+(1/7)}

=> b^ {14+1/7}

=> b^{15/7}

=> \sqrt[7]{b^{15}}
