Answer:
The equation representing Total money spend being as a member is 
Step-by-step explanation:
Given:
Memberships charges = $60
Cost of 1 book = $7.60
Let number of books be 'b'.
We need to find Total money 'm' spend yearly on buying books after becoming member.
Now we know that 1 book is free for a member.
Total money spend 'm' will be equal to Sum Memberships charges and Cost of 1 book multiplied by number of books bought yearly minus 1.
Framing in equation form we get;

Hence The equation representing Total money spend being as a member is 
Answer:
The equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is 
Step-by-step explanation:
Equation of line passing through the points (-7,25) and (-4,13) in slope-intercept form.
The general equation of slope-intercept form is: 
First we need to find slope
The formula used for finding slope is: 
We are given: 
Putting values in formula and finding slope

So, slope m= -4
Now finding y-intercept
Using slope m=-4 and point (-7,25) we can find y-intercept

So, y-intercept b =-3
Now, the equation of required line having slope m=-4 and y-intercept b=-3 is:

So, the equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is 
So permiter=masure of all sides added together
so sides are(3x+2), (2x+5), and (4x)
so (3x+2)+(2x+5)+(4x)
use associative property
a+(b+c)=(a+b)+c so
(3x+2)+(2x+5)+(4x)=3x+2+2x+5+4x
group like terms becasue can move numbers around
(3x+2x+4x)+(2+5)
add like terms
(9x)+(7)
9x+7
he will use 9x+7=perimiter
Answer:
Divide each term by -5 and simplify
Step-by-step explanation
-5/-5=1
-5/-80=16
x<16
