Formalize the following argument by using the given predicates and then rewriting the argument as a numbered sequence of statements. identify each statement as either a premise, or a conclusion that follows according to a rule of inference from previous statements. in that case, state the rule of inference and refer by number to the previous statements that the rule of inference used.
(a) everybody who is at least 16 years old can get driver licence. azul does not have a driver licence yet. therefore, azul is less than 16 years old. predicates: s(x)= x is at least 16 years old, d(x)=x can get a driver licence". the domain of discourse is all people. (b) dogs bark at cats. max is a dog. moonbeam is a cat. therefore, max barks at moonbeam predicates: b(x, y)="x barks at y", d(x)="x is a dog" and c(x)="x is a cat". the domain of discourse is all animals.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
