Sean V = {-2, -1, 0, 1, 2} y la función g : V →IR, definida por g(x) = x2 + 1. El recorrido de g. es: a {0,1,2}
b{1,2,5}
c{-2,-1,0}
d{0,1,5}

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

2x^2+5x+17

your welcome. : )

you can't solve x because it is 2 linear equation and you only have one equation

step-by-step explanation:

the true ones are a b and d
