Answer:
14x-2
Step-by-step explanation:
3 1/2 = 7/2
so than 7/2 pounds cost 1,96
than 1 pound cost x
-----------------------------------------
x = 1*1,96/(7/2) = (1,96 *2)/7 = 3,92 /7 = 0,56 so will cost $,56 so choice a. is right sure
Answer:
y=-1x+3
Step-by-step explanation:
Slope intercept form: y=mx+b
x intercept (3,0)
y intercept (0,3)

start subbing in numbers from one of the points. I'm using hte x intercept so it would be (0,3). m = slope
y=mx+b
3=-1*0+b
3=0+b
b=3
so now that you know what b and the slope is,
y= -1x+3
Answer:
(a) 17/20 b.5/18/25 c. 1.255
The range should be 49. To find the range you do the highest number subtract the lowest number.
Hope this helped.
