O-4
O-2
O 2
O 6
__________
[tex] \: [/tex]
[tex]( \frac{1}{9} ) {}^{a + 1} = {27}^{2 - a} [/tex]
[tex]( {3}^{ - 2} ) {}^{a + 1} = ( {3}^{3} ) {}^{2 - a} [/tex]
[tex] \cancel{ {3}}^{ - 2a - 2} = \cancel{{3}}^{6 - 3a} [/tex]
-2a - 2 = 6 - 3a
-2a + 3a = 6 + 2
a = 8✔

what is the x and y intercept of 18x-3y=15
Answer:
18(0) -3y = 15
-3y=15
now divide-3 from both sides
y= 15/-3
reduced is -5
y int = (0,-5)
18x-3(0)=15
18x=15
divide the 18 from both sides
x=15/18
reduced is 5/6
x int = 5/6

5. for Store A- 4 pairs of jeans is $120 so if you divide that which is 120/4 it gives you 30 so it would mean your paying $30 for each pair of jeans
for Store B- 2 pairs of jeans will cost you $100 so if you add 50+50 it gives you a hundred so it means your paying $50 for each pair of jeans
for Store C- 3 pairs of jeans is $99 so if you divide 99/3 its 33 which means you would be paying $33 dollars for each pair of jeans
so out of all of then Store A gives you the best deal.
