[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✔

Show your work. -2.5(4x -4) = -6
Answer:
x = 1 3/5
Step-by-step explanation:
distribute.
-2.5*4x + (-2.5*-4) = -6
-10x +10 = -6
subtract 10 on both sides
-10x = -6 -10
divide by -10
x = -16/-10
x = 1 3/5

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
4 x - 6y x = 3 y = 2

Find a polynomial f(x) of degree 4 that has the following zeros. 7, −3, 0, −2
Answer:
x^4 - 2x^3 - 29x^2 - 42x
Step-by-step explanation:
Equal all the zeros to x then move them over.
x=7,x=-3,x=0,x=-2
x-7,x+3,x+0,x+2
Then multiply each factor
(x-7)(x+3)(x)(x+2)
x^4 - 2x^3 - 29x^2 - 42x

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.
