Which is the graph of 2x – 4y > 6? On a coordinate plane, a dashed straight line with a positive slope goes through (negative
2, negative 2) and (1, 0). Everything to the right of the line is shaded. On a coordinate plane, a dashed straight line with positive slope goes through (negative 3, negative 3) and (3, 0). Everything to the left of the line is shaded. On a coordinate plane, a dashed straight line with a positive slope goes through (negative 2, negative 2) and (1, 0).

Answer:
The graph in the attached figure
Step-by-step explanation:
we have
solve for y
Divide by -4 both sides
Remember
when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
The solution of the inequality is the shaded area below the dashed line
The slope of the dashed line is positive m=0.5
The y-intercept of the dashed line is (0,-1.5)
The x-intercept of the dashed line is (3,0)
therefore
The graph in the attached figure

Answer:
0.50 kg of the material would be left after 10 days.
0.25 kg of the material would be left after 20 days.
Step-by-step explanation:
We have been given that the half-life of a material is 10 days. You have one 1 kg of the material today. We are asked to find the amount of material left after 10 days and 20 days, respectively.
We will use half life formula.
, where,
A = Amount left after t units of time,
a = Initial amount,
t = Time,
h = Half-life.
Therefore, amount of the material left after 10 days would be 0.5 kg.
Therefore, amount of the material left after 20 days would be 0.25 kg.
