5 is b and 1 is a
1 is A because just change the x value with the number in the table for x and see if y matches like 
Y=-2x+6 
Y=-2*1 + 6
4 =-2*1+6
And for 5 
Day is x, y is depending on x and your going to add .4 to everything. But it’s growing .2 every day so it’s 
Y=0.2x+0.4 
I hope this helps you if I’m not right please tell me so if other people use those they know I’m wrong if I am. I don’t think so thou. If not please give me brainiest. Thank you!! 
Have a nice night.

Answer: 37
Step-by-step explanation:
Given : Significance level : 
Critical value : 
margin of error : E= 1 mile per gallon
Population standard deviation:  miles per gallon.
 miles per gallon.
We know that when the population standard deviation is known then the formula to find the sample size is given by  : 

 [Round to the next whole number.]
  [Round to the next whole number.]
Hence, the required number of automobiles should be used in the test = 37

Does dilation preserve angle measure?
When a point, side, line, or angle is dilated; the length of the line will be altered by the ratio or scale of dilation.
However, the measure of angle will remain the same.
<em>Hence, the given statement is true.</em>
 
        
             
        
        
        
Answer:
6 I think
Step-by-step explanation:
7 + 5(x - 3) = 22
7 + 5x - 15 = 22
7 + 5x = 37
5x = 30
x = 6
{ 6 }
 
        
             
        
        
        
2m^4
So basically choose B. You basically had to find the prime factors of each term in order to find the GCF
