Terrell wrote that 5 – 4.2 = 8. Which statement about his answer is true? CLEAR CHECK 8 is wrong because a number gets smaller, not larger, when you take 4.2 from it. 8 is right because 50 – 42 = 8. 8 is right because 4.2 + 8 = 5. 8 is wrong because you cannot subtract a decimal from a whole number.

a) is wrong because a number gets smaller, not larger, when you take 4.2 from it

Step-by-step explanation:

Given

Required

Determine which of the options is true

First, we need to solve for 5 - 4.2

Compare this answer with Terell's answer (8)

We observe that:

This implies that; Terell is wrong

The two options that support the answer being wrong are (a) & (d)

Analyzing (a):

5 should get smaller when 4.2 is subtracted from it.

This isn't the case in Terell's solution.

Hence, (a) is true

Analyzing (d):

d is wrong because a decimal can be subtracted from a whole number

Hence, (a) answers the question

step-by-step explanation:

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
