Which shape has exactly two pairs of perpendicular sides?

2 answers:

8 0

The correct answer for this question would be option 1. SQUARE. Among the choices, it is only square that has exactly two pairs of perpendicular sides. When we say perpendicular, this means that the angles are of 90 degrees. Not option 3, because not all quadrilaterals have exactly two pairs of perpendicular sides. Hope this answer helps.

What is the solution to the compound inequality in interval notation?

ohaa [14]

The given compound inequality is

$2(x+3)>6 \ or \ 2x+3\leq -7$

First we solve the first inequality,

$2(x+3)>6
\\
x+3 >3
\\
x>0$

Now we solve the second inequality

$2x+3\leq -7
\\
2x \leq -7-3
\\
2x\leq -10
\\
x\leq -5$

So we have

$x > 0 \ or \ x\leq -5$

So the required solution is

$( - \infty,-5] \ or \ (0, \infty)$

Correct option is A .

Discussion:

For every value of x, g(x) = f(x) -1 meaning that the y-value of g(x) is 1 less than the corresponding y value of f(x). So the graph of g(x) is "below" f(x) or it is translated 1 unit downward from f(x)
