Answer:

Associative  

Step-by-step explanation:

The associative property of addition states that you can add numbers however they are grouped inside parentheses.  

It doesn't matter where you put the parentheses. You will always get the same answer.

For example,

\begin{array}{rcl}(5 + 3) + 7 & = & 5 + (3 + 7)\\8 + 7& = & 5 + 10\\15 & = & 15\\\end{array}

a dog eats 5 cups of food a day. a pound of food contains 10.5 cups. how much does it cost to feed the dog each day if a 50 lb b
Stells [14]
So, the dog eats 5 cups a day and 1 pound of dog food is 10.5 cups.

A 50 lb bag is<span> $22.50.

Since you're asking how much it would cost to feed it a day we need to find out how much 1 pound of food costs.

</span>22.50 / 50 = 0.45

So, it's 0.45 for 1 lb. But 1 lb is 10.5 cups, not 5.

0.45 / 5 = 0.09

So, I believe it would cost 0.09 each day to feed the dog.

Identify the slope and y-intercept. If the equation is in standard form, you may need to switch it to slope-intercept form. Sket
evablogger [386]

Answer:

The slope of line = m = 6

The y-intercept = b = 3

Please check the attached graph below.

Step-by-step explanation:

Given the line

y = 6x + 3

We know that the slope-intercept form of the line is

y = mx+b

here

  • m is the slope
  • b is the y-intercept

now compare the slope-intercept form with the given line

y = 6x + 3

so

The slope of line = m = 6

The y-intercept = b = 3

Please check the attached graph below.
