Answer: Choice C. 
============================================
Explanation:
The domain is the set of all allowed x inputs.
Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.
We can say the domain is
which can be simplified to
or 
In short: x can be -3 or larger.
Answer:
Step-by-step explanation:
x = 52° + 90° ( exterior angle of a triangle is equal to the sum of two opposite interior angles )
x = 142°
First add like terms in this case 1+7=8. Then then divide. 2x/8= 4. X=4
So
<span>20% of 18.50 = ____ </span>
<span>to get this you multiply </span>
<span>20% is .20 in decimal form </span>
<span>18.50 x .20 = $3.70 </span>
<span>so 20% is $3.70, which means the discount is $3.70 </span>
<span>so then you subtract $3.70 from the original price of 18.50 and you get </span>
<span>$14.80 which is your answer (:</span>
