You have to input each solution into the equation.
let’s start of with (12,0)
12-9(0)=12
12=12 <— which is true so it’s this one
let’s do the other ones to check
now let’s do (0,12)
0-9(12)=12
-108=12 <— not true
(3,-1)
3-9(-1)=12
13=12 <— not true
(0,-4/3)
0-9(-4/3)= 12
12=12 <— also true
the answer would be (12,0) and (0,-4/3). i’m not sure whether or not it’s a select all that apply question. i hope this helps

Answer:
A ≈ 65.4°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the trig relations associated with pairs of sides. For angle A, given sides b and c are the adjacent side and the hypotenuse, respectively. The appropriate relation is ...
Cos = Adjacent/Hypotenuse
cos(A) = b/c
A = arccos(b/c) = arccos(2.5/6)
A ≈ 65.4°
Remember a fraction is just division,
So 37.5 would be 75/2 as that would equal 37.5.
Answer:
x=30
Step-by-step explanation:
3(x+2)^3/5 +3=27
Subtract 3 from each side
3(x+2)^3/5 +3-3=27-3
3(x+2)^3/5 =24
Divide by 3
3/3(x+2)^3/5 =24/3
(x+2)^3/5 =8
Take everything to the 5/3 power to get rid of the exponent on the left side
(x+2)^3/5 ^ 5/3=8 ^ 5/3
Remember that a^b^c = a^ (b*c)
(x+2)^(3/5 * 5/3)=8 ^ 5/3
(x+2)=8 ^ 5/3
Replace 8 with 2^3
(x+2)=2^3 ^ 5/3
Remember that a^b^c = a^ (b*c)
(x+2)=2^(3 * 5/3)
x+2 = 2^5
x+2 = 32
Subtract 2 from each side
x+2-2 = 32-2
x=30
