Find the error in the calculations below:

Line (1): [tex]-2(-5x + 4) \geq -10[/tex]

Line (2): [tex]-5x + 4 \geq 5[/tex]

Line (3): [tex]-5x \geq 1[/tex]

Line (4): [tex]x \leq -\frac{1}{5}[/tex]

A. The error occurred from line (3) to line (4).
B. The error occurred from line (4) to line (5).
C. The error occurred from line (1) to line (2).
D. The error occurred from line (2) to line (3).



Answer :

Let's carefully examine the steps provided to identify where the error occurs.

### Line (1) to Line (2):

Line (1): [tex]\(-2(-5x + 4) \geq -10\)[/tex]

First, distribute [tex]\(-2\)[/tex] on the left-hand side:
[tex]\[ -2 \cdot -5x + (-2) \cdot 4 \geq -10 \][/tex]
This simplifies to:
[tex]\[ 10x - 8 \geq -10 \][/tex]

Adding 8 to both sides to isolate the term with [tex]\(x\)[/tex]:
[tex]\[ 10x \geq -10 + 8 \][/tex]
[tex]\[ 10x \geq -2 \][/tex]

Dividing both sides by 10:
[tex]\[ x \geq -\frac{2}{10} \][/tex]
[tex]\[ x \geq -\frac{1}{5} \][/tex]

Therefore, we see that the expression [tex]\(-5x + 4 \geq 5\)[/tex] in Line (2) isn't correct based on the steps we showed. Line (1) to Line (2) is the point where the error occurred.

### Verification of other steps:

Let's still go through Line (2) to Line (3) for completion:

Line (2): [tex]\(-5x + 4 \geq 5\)[/tex]

Subtract 4 from both sides:
[tex]\[ -5x \geq 1 \][/tex]

This step is correct. No error here.

Line (3) to Line (4):

Line (3): [tex]\(-5x \geq 1\)[/tex]

Divide both sides by [tex]\(-5\)[/tex]. Remember to flip the inequality sign when dividing by a negative number:
[tex]\[ x \leq -\frac{1}{5} \][/tex]

This step is also correct.

Since in Line (5), no further steps are shown, there are no errors to analyze beyond Line (4).

### Answer:
The error occurred from Line (1) to Line (2).
