Answer:b
Step-by-step explanation:
Answer: domain = 54 range = 14
Step-by-step explanation:
<span>If x represent the number of nickels in the box and y represent the number of dimes in the box (note that x>0 and y>0), then the total value of x nickels is $5x and total value of y dimes is $10y. Adding these amounts of money you get that in money box was $</span><span><span>(5x+10y)</span>.</span>
<span> Sally knows that she has less than $20 in the box, then 5x+10y<2000 ($20=2000 cents).
</span>
Since this inequality is strict, then you should draw the dashed line 5x+10y=2000. The line divides coordinate plane into two parts.
Pick point (0,0) and consider to which part this point belongs. Since 5·0+10·0<2000, you can conclude that (0,0) is a solution of given inequality and belongs to needed part. Hence you should take the shaded part below the line for positive values of x and y.
1 / 4 = 2 / 8 ;
2 / 8 > 1 / 8 => 1 / 4 > 1 / 8;
- 1 / 4 = -0.250;
-1 / 8 = - 0.125;
0.250 > 0.125 => -0.250 < - 0.125 => - 1 / 4 < -1 / 8;
