Acheese maker changes the temperature of her milk at a rate of -2 per minute. what is the change in the temperature of the milk after 25 minutes?

50 degrees

Step-by-step explanation:

1. Write an equation for this.

y=-2x

Where y=temperature of the milk and x=minutes spent

2. Solve for y by plugging in 25 for x.

y=-2(25)

y=-50

3. Answer

The change is 50 or negative 50 degrees.

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
