Answer:

0.09

Step-by-step explanation:

avg rate of change is:  change in y/ change in x

so it´d be   3.59 - 0.89 / 2014 - 1984

= 2.7/ 30

= 0.09

note:

The slope formula and the average rate of change formula are the same, just written a bit different, so you could also use:

y2 - y1 / x2 - x1

Explain why one half times two equals one whole
djverab [1.8K]
Two halfs equal one whole. think of it like this, an orange cut in half leaves you with two halfs, put them together and you have a whole. simple. multiplying by 2 just means adding a number two times.
1 half plus one half= 2halves= 1 whole
1half x 2= 2 halves=1 whole

Mr. Green orders some cookies from a local youth group. Using his order form shown below, complete the last column to find the t
evablogger [386]

From the computation done, it can be denoted that the total price that will be paid will be $12.90.

1 Krispy Kosmos at $2.89 = $2.89

2 Chewy Chocos at $3.19 each = 2 × $3.19 = $6.38

1 Gooey Globs at $2.99 = $2.99

Total = $2.89 + $6.38 + $2.99 = $12.26

We'll then add the sales tax of 5.2%, therefore, the total value will be:

= $12.26 + (5.2% × $12.26)

= $12.26 + $0.638

= $12.90

In conclusion, the correct option is $12.90.

hammer [34]

Answer:

r = 32,546.69 * 1.03^t

Step-by-step explanation:

33,523.09/32,546.69 = 1.03

34,528.78/33,523.09 = 1.03

35,564.65/34,528.78 = 1.03

The common ratio between values is 1.03.

The initial value is 32,546.69

The is exponential growth with initial value 32,546.69 and a growth factor of 1.03.

Equation:

y = a(1 + i)^t

r = 32,546.69 * 1.03^t

Combine like terms and apply the distributive property to create an equivalent expression:
chubhunter [2.5K]

Answer:

Equivalent expression is 15a+8b

Step-by-step explanation:

Given expression is,

2\left(5a+3b\right)+5a+2b

First step is to apply distributive property. The property states that,

a\left(b+c\right)=ab+ac

Applying the property,

2\left(5a\right)+2\left(3b\right)+5a+2b

Simplifying,

10a+6b+5a+2b

Collecting like terms,

10a+5a+6b+2b

Combining the like terms,

15a+8b

Therefore, equivalent expression is 2\left(5a+3b\right)+5a+2b=15a+8b
