1 answer:

4 0

$f(x)=3^x+10x;\ g(x)=2x-4\\\\(f+g)(x)=f(x)+g(x)=(3^x+10x)+(2x-4)=3^x+10x+2x-4\\\\\text{combine like terms}\\\\=3^x+(10x+2x)-4=\boxed{3^x+12x-4}$

A bakery sells 10 peanut butter cookies for a total of $7.00. Find the unit rate

mariarad [96]

Answer: $0.70 per cookie

Which is the same as saying 70 cents per cookie

=============================================================

Explanation:

The unit rate is the cost of one cookie. The term "unit" means "one".

10 cookies = 7 dollars

10/10 cookies = 7/10 dollars ...... divide both sides by 10

1 cookie = 0.70 dollars

Since one cookie costs $0.70, the unit rate is $0.70 per cookie or you can say 70 cents per cookie.

How does knowing the double 6+6=12 help you solve the near double 6+7=13

forsale [732]

Answer:

6 + 7 = 13

Step-by-step explanation:

We are given the following information in the question:

We know that

$6 + 6 = 12$

We need this information to evaluate

$6+7$

The evaluation can be done with the help of using associative property and distributive property.

Associative property: (a + b) + c = a + (b + c)

The evaluation can be shown as:

$6 + 7\\= 6 + 6 + 1\\=(6 + 6) + 1\\= 12 + 1\\=13$
