The label on the car's antifreeze container claims to protect the car between −40°C and 140°C. To covert Celsius temperature to Fahrenheit temperature, the formula is C= 5/9(5-32). Write a compound inequality to determine the Fahrenheit temperature range at which the antifreeze protects the car. a. -40 5/9(f-32) >140 b.5/9(f-32) 5/9(f-32)>140
d.-40 < 5/9(f-32) <140

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

the 3rd on is correct

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
