Answer:

Step-by-step explanation:
Formula for straight lines: 

where m = slope, b = constant
Given:
y-intercept = -3 (0, -3)
m = ⅛
Substitute into formula to find b.

Substitute b into original formula

If the value of the baseball card increases by 3% per year then we can say that each year the value of the card may be multiplied by 103% = 1.03, thus:
Value after n years = original price*(1.03)^n
Value after 15 years = 75*(1.03)^15
 = $116.85
        
             
        
        
        
Answer:
500 and 700
Step-by-step explanation:
It says '7 hundreds' referring to 700. and it then say the second number has 2 fewer, two fewer hundreds is 200. so the two numbers are 500 and 700.
 
        
             
        
        
        
Answer:
a = 2, b = 3.5
Step-by-step explanation:
Expanding  using Binomial expansion, we have that:
 using Binomial expansion, we have that:
  =
 =


We have that the coefficients of the first two terms are 128 and -224.
For the first term:
=>  
 
=> ![a = \sqrt[7]{128}\\ \\\\a = 2](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%5B7%5D%7B128%7D%5C%5C%20%5C%5C%5C%5Ca%20%3D%202)
For the second term:
 
 
 
 

Therefore, a = 2, b = 3.5
