Answer:

\boxed{\sf Associative \:property\: of \:addition}

  • \sf (4 + 5) + 2 = 4 + (5 + 2)

\boxed{\sf Distributive \:property}

  • \sf 2(2x + 4) = 4x + 8

\boxed{\sf Associative\: property \:of \: multiplication}

  • \sf ( 7 * x ) *3 = 7 (x *3)

\boxed{\sf Commutative \:property\: of \:multiplication}

  • \sf ( 8* x *2) = (x *8* 2)

\boxed{\sf Commutative \:property \:of \: addition}

  • \sf ( 7 + 3) + 1 = 1 + (7 + 3)

________________________________

Associative property of addition: Changing grouping of addends doesn't change the sum.

Distributive property: Multiplying a sum by a number is the same as multiplying each addend by that number and then adding the two products.

Associative property of multiplication: Changing grouping of the factors doesn't change the products.

Commutative property of multiplication: Changing order of the factors doesn't change the products.

Commutative property of addition:  Changing order of addends doesn't change the sum.

Tamara has decided to start saving for spending money for her first year of college. Her money is currently in a large suitcase
katovenus [111]

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.

In 2010, the number of houses built in Town A was 25 percent greater than the number of houses built in Town B. If 70 houses wer
Stella [2.4K]

Answer:

The number of houses built in Town B is 56.

Step-by-step explanation:

We are given that in 2010, the number of houses built in Town A was 25 percent greater than the number of houses built in Town B.

Also, 70 houses were built in Town A during 210.

Let the number of houses built in Town B be 'x'.

So, according to the question;

Number of houses built in Town A = Number of houses built in Town B + 25% of the houses built in Town B

70 = x + (25\% \times x)

70 = x(1+0.25)

x=\frac{70}{1.25}

x = 56

Hence, the number of houses built in Town B is 56.

How do I make the table? With what numbers?
zaharov [31]
The numbers they are looking for are numbers that are simple but made up. For example, start with 0. Plug 0 in for x, so the corresponding value of y is 10. For a second value, you could do 2. When x=2, y=11, etc. So essentially, put in some simple numbers for x, and solve for y. :)
