The greatest common factor of 49a^4b^3 and 21a^4b^5

7a^4b^3

Explanation/Steps to solve:

First you separate 49 and 21 from the variables. Then you find their GCF.

The GCF of 49 is 21 is 7.

Then you find the GCF of the variables.

a^4b^3 and a^4b^5

how many As and Bs do they have in common?

both variables have 4 As and both have 3 Bs. It can't be 5 Bs since the other variable only has 3. 3 is less than 5 which means that there can be a 3 in the other variable (b^5).

So we rewrite how much As and Bs they have.

4 As = a^4

3 Bs = b^3

---> a^4b^3

then we combine both the GCF of the numbers and the variables,

7a^4b^3

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
