Step-by-step explanation:
It's the <em>DISTRIBUTIVE PROPERTY</em>:
m(a + b) = ma + mb
Other properties:
Commutative Property:
<em>of addition: a + b = b + a</em>
<em>of multiplication: a · b = b · a</em>
Associative Property:
<em>of addition: (a + b) + c = a + (b + c)</em>
<em>of multiplication: (a · b) · c = a · (b · c)</em>
Answer:
C aka the third one
Step-by-step explanation:
The point-slope form is:
So, here, you just plug in values:
It would be + 1 because remember, the '-' sign just means the opposite of, not subtraction in this case. Also, m = slope.
Answer:
Total charge per month = $ 16 + (0.08) * x
equation for having same charge
0.08 x - 0.12 y = 8
Step-by-step explanation:
Part 1:
Monthly fee = $ 16
Per check fee = $ 0.08
Checks signed in month = x
Total Charge monthly = Monthly fee + Checks fee
Putting the values
Total charge per month = 16 + (0.08) * x ...........(i)
Part 2: Let she signs y checks for account B
Monthly fee of B = $ 14
per check fee = @ 0.12
Total Charge = monthly fee + checks fee
= $ 14 + y *(0.12) ..................(ii)
For having same value in the bank then equation (i) and (ii) shuld be equal to each other
i.e.
16 + 0.08x = 24 + 0.12y
0.08 x - 0.12 y = 24-16
0.08 x - 0.12 y = 8
this will be the equation
