B={x|x is an even whole no less than 9}
Now
Answer:
D) When x=2, y=14 When x=4, y=28
Step-by-step explanation:
By using slope= y2-y1/x2-x1
I get (1,7) and (3,21) from the table
slope= 21-7/3-1= 14/2= 7
Then I plug in the values into y=mx+b
7= 7(1) +b
b= 0
Getting an equation of y=7x
When x= 2
y= 7(2)= 14
When x= 4
y= 7(4)= 28
1) 9x-4
7x+2x= 9x
-8+4= -4
9x-4
the answer is...
42 over 100
or
21 over 50
