Answer:

the equation | 5x + 10| = -7 has no solution for x ∈ R.

Step-by-step explanation:

Given the absolute value equation

| 5x + 10| = -7

We know that absolute value is always positive.

Reason:

The reason is that the absolute value is the distance from the number 0. Hence, it can not be less than or equal to a negative number.

Conclusion:

Therefore, we conclude that the absolute value of any number would be either 0 or positive as it can not less than or equal to a negative number.

Therefore, the equation | 5x + 10| = -7 has NO SOLUTION for x ∈ R.

Austin checks the temperature at 10:00 p.m. He notices if the temperature

Alecsey [184]

Answer:

A. t - 5 < 26°

Step-by-step explanation:

Record low temperature for that date = 26°

Temperature at 10:00 PM = t

A fall in temperature by 5° = t - 5

Thus, this is said would mean the record low temperature would be breaking at this point, meaning the new temperature low recorded will be less than 26°.

In mathematical expression, this is expressed as;

t - 5 < 26°

What equation is represented by the equation on the graph ?

solmaris [256]

Answer: The correct option is D.

Explanation:

From the graph we noticed that the x intercept of the line is (2,0) and the y-intercept is (0,2).

If the line passing through two points then the equation of line is,

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Since the ien passing through (2,0) and (0,2).

$y-0=\frac{2-0}{0-2}(x-2)$

$y=-1(x-2)$

$y=-x+2$

This equation is represented by option D, therefore the option D is correct.
