Option 1. The equation that represents the direct variation that exists between a and b is b = –a.
<h3>How to find the direct variation here</h3>
The direct variation is of this form y ∝ x
This gives the equation
y = kx
The constant is k
From our question we have
b ∝ a so b = ka
b = 
a = 
Remember that b = ka
This would cancel out to
1 = -k
or k = -1
Hence the equation would be written as
b = -a

Answer:
y = x + 6
Step-by-step explanation:
Answer:
Step-by-step explanation:
First you need to find the price for one binder. If 2 binders cost 4.36 you have to divide by 2 to find the price for 1. You should get 2.18. Then you have to see how many times you can multiply 2.18 without having the product go over 2.18. 2.18 • 22 = 47.96, the number closest to 50 without going over. Therefore, she can buy 22 binders.
Sorry I don’t now the answer to this problem
Answer:
C
Step-by-step explanation:
The first term -2 is also -B; therefore A and B can be eliminated.
-1+3 is 2, and -4 is the only term used in the formula, so D is also eliminated
