The temperature at a mountain base camp was −5 degrees Celsius on Wednesday. Thursday morning, the temperature was 2 degrees Celsius lower than it was on Wednesday. By Thursday evening, the temperature was 1 degree Celsius lower than it was that morning. What was the temperature at the base camp Thursday evening? A: −9 degrees Celsius
B: −8 degrees Celsius
C:−7 degrees Celsius
D: −6 degrees Celsius

I think it's B: -8 degrees Celsius

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
