Which is the solution to the inequality?

y greater-than-or-equal to negative 40

y less-than-or-equal to negative 40

y greater-than-or-equal to 14

y less-than-or-equal to 14

What is another way to write the equation ?

7 (StartFraction x over 8 EndFraction) + three-fourths = negative 6

StartFraction 7 + 3 over 8 + 4 EndFraction x = negative 6

StartFraction 7 over 8 EndFraction + three-fourths x = negative 6

StartFraction 7 over 8 EndFraction x minus three-fourths = 6

The first step to solve the equation is shown below.Which property was applied in this step?

Addition Property of Equality

Subtraction Property of Equality

Multiplication Property of Equality

Division Property of Equality

Which method correctly solves the equation using the distributive property?

Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x minus 4 = negative 1.7. Negative 0.2 x = 2.3. x = negative 11.5.

Negative 0.2 (x minus 4) = negative 1.7. x minus 4 = 0.34. x = 4.34.

Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x + 0.8 = negative 1.7. Negative 0.2 x = negative 2.5. x = 12.5.

Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x minus 0.8 = negative 1.7. Negative 0.2 x = negative 0.9. x = 4.5.
