Choose the graph of the inequality x>-2

B

Step-by-step explanation:

Okay, first a trick that you can use is to cross out the answer choices that show x is smaller than -2. The inequality tells that x is larger that -2, so it cannot be C or B.

Now you would think about open circles and closed circles. Open circles are for signs such as "greater than" or "less than". Closed circles are "Less than or equal to" and "Greater than or equal to".  That is a way to know whether a answer choice is correct of not.

But not for this question. You can automatically say B is correct. The inequality says the number is -2. Which answer choice between A and B starts at -2? The answer would be B.

Hope this helped!!

B

Step-by-step explanation: It is the best answer because it is an unfilled circle, meaning greater than but not equal to and it is moving towards values greater than -2

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!

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
