Answer:
<u><em>9 (3x+2)</em></u>
Step-by-step explanation:
<u>27x + 18 = 9 (3x+2)</u>
<em>By simplifying the Given expression you get 9 (3x+2) </em>
<em>and no matter how many times you simplify that expression you always get the expression you started with so in other word their equavalent to each other</em>

Answer:
p1= 95, p2 = 180
Step-by-step explanation:
We have population : 50 given that population grows by 90% per year
So, After one year: new population (p1) will be
p1 = 50 + 50*0.9 = 50 + 45 = 95
Now, After two years: new population (p2) will be
p2 = 95 + 95*0.9 = 95 + 85.5 (approximately = 86) = 95 + 86 = 180
Therefore,
p1 = 95, and p2 = 180.
Answer:
it is not a direct variation
Step-by-step explanation:
To have a direct variation
y/x = k for all values of x and y
y/x = 11/7
y/x = 13/8
y/x = 15/9 = 5/3
y/x = 17/10
11/7 does not equal 13/8 so it is not a direct variation
Answer:
Step-by-step explanation:
take 56 degree as reference angle
using sin rule
sin 56=opposite/hypotenuse
0.82=AB/15
15*0.82=AB
12.3=AB
Answer: Yes
Step-by-step explanation:
x = 3
y = -7
10x + 20y ≥ -3
10 (3) + 20 (-7) ≥ -3
30 + (-140) ≥ -3
30 - 140 ≥ -3
-110 ≥ -3
(3, 7) is a solution
