Answer:

B. 30

Step-by-step explanation:

A line is 180 degrees, so when we have 100, we subtract that from 180 to get the interior angle of 80.

A triangle has a sum of 180, so we just subtract 80 and 70 from 180 to get 30.

Hope this helps

What is the solution set of the quadratic inequality f(x) greater than or equal to 0

stellarik [79]

ANSWER

{ $x | x \in \: R$ }

EXPLANATION

From the graph, the given quadratic inequality is

${(x + 3)}^{2} \geqslant 0$

We can see that the corresponding quadratic function is a perfect square.

Since the graph opens upwards and it is always above the x-axis, any real number you plug into the inequality, the result is greater than or equal to zero.

Hence the solution set is

{ $x | x \in \: R$ }

The correct answer is A
