Choose the inequality that represents the following graph

your answer of D) is correct x >= to 0

Step-by-step explanation:

it's cause first off the dot on zero is filled in meaning >= or <=

then the line is shaded to the right of zero so x must be greater then zero

so combining both of these we can conclude that  x >=0 or D is correct.

khan academy hm? yes khan academy rules lol

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!
