Answer:

6. Should be 10

8. X=120 degrees

Step-by-step explanation:

6. If you add 5+2+3, it equals 10

8. two of the sides are right angles. Together, they add up to be 180 degrees. the other angle is 60 degrees. 180 and 60 together are 240. Then, subtract from 360 since your shape is a quadrilateral. 360-240=120

Midpoint formula:

$(x,y ) = (\frac{x_{1}+x_{2} }{2} ,\frac{y_{1} +y_{2} }{2})\\= (\frac{3+7}{2}, \frac{-1+(-5)}{2} )\\=(\frac{10}{2}, \frac{-6}{2} )\\= (5,-3)$

Let f(x) = 13 - |2x+ 1|. Find all x for which f(x) less than or equal to 14

Art [367]

Answer:

$x \leqslant -1\: or \: x \geqslant - 1$

Step-by-step explanation:

The given function is

$f(x) = 13 - |2x + 1|$

We want to find all values of x for which:

f(x) is greater than or equal to 14.

This implies;

$13 - |2x + 1| \geqslant 14$

Subtract 13 from both sides;

$- |2x + 1| \geqslant 14 - 13$

$|2x + 1| \geqslant - 1$

By definition of the absolute value function,

$- (2x + 1) \geqslant - 1 \: or \: (2x + 1) \geqslant - 1$

Divide through the first inequality and and reverse the inequality sign:

$2x + 1 \leqslant -1 \: or \: 2x + 1 \geqslant - 1$

$2x \leqslant -1 - 1 \: or \: 2x \geqslant - 1 - 1$

$2x \leqslant -2 \: or \: 2x \geqslant - 2$

$x \leqslant -1\: or \: x \geqslant - 1$
