Answer:
<h2>66 and 66</h2>
Step-by-step explanation:
opposite angles are equal
12x - 18 = 8x + 10
combine similar terms:
12x - 8x = 10 + 18
4x = 28
x = 28/4
x = 7
plugin the value of x=7 back into the equation to solve the angle
= 12x - 18
= 12(7) - 18
= 66
= 8x + 10
= 8(7) + 10
= 66
Answer:
36
Step-by-step explanation:
25% × ? = 9
? =
9 ÷ 25% =
9 ÷ (25 ÷ 100) =
(100 × 9) ÷ 25 =
900 ÷ 25 =
36
100+ 100+ 100+ 9= 309
200+ 50 +50= 300

Answer:
C
Step-by-step explanation:
For the first one, there is a ratio of change greater than one so that is exponential growth.
The second one has exponential decay but its x is negative making it actually exponential decay even if graphed.
The third one has positive growth over an interval of negative x, so in terms of x there is exponential decay.
The fourth one is neither and if graphed is just points as there is a specific solution set.
In conclusion, the third is exponential decay!
Hope this helps :)
