A. Y= -7.50x+585(not entirely positive on this one ,but we are learning this in school right now for me)
B. y=-7.50(15)+585
C. solve the equation up above so multiply -7.50 by 15 (weeks) which would give you -112.50 then add 585 which gives you 472.50 which should be your answer
so there is 472.50 dollars left in account after one year.
hope this helped!
The two numbers that have a product of 48 are 6 and 8 or 12 and 4, etc. They can be multiplied together to get 48, which is the product of the two numbers.
The formula for finding the product of two numbers is to multiply them together. For example, if you have two numbers, a and b, the product of these two numbers is a multiplied by b or an a x b.
The two numbers that have a product of 48 and a sum of 16 are 4 and 12. You can multiply 4 and 12 together to get 48, and you can add them together to get 16.
When the product of two numbers is one of each number, the other number is 1. This means that when the product of two numbers is the same as one of the numbers, the other number must be 1, as 1 multiplied by any number is always equal to itself.

Basically here all you want to do it substitute the values x=1 and x=2 for the given function. Use your slope formula
.
Do same for x=3 and x=4
You next divide plug in values in to this expression:
![\frac{Slope of B}{Slope of A}](https://tex.z-dn.net/?f=%5Cfrac%7BSlope%20%20of%20%20B%7D%7BSlope%20%20of%20%20A%7D)
<h2>(3x+4)+2(3x+4)=117</h2>
<h2>= (3x+4)+(6x+8)=117</h2><h2>= 3x+4+6x+8=117</h2><h2>= 9x+12=117</h2><h2>= 9x = 117-12 </h2><h2>= 9x = 105</h2><h2>= x =105 ÷ 9</h2><h2>= x = 11.6666666667</h2>
<h2>Hence,x = 11.6666666667</h2>
