item 3
andy found three ordered pairs, (0, 250), (5, 575), and (10, 900), for the equation, y = 65x + 250.
when he graphs these, what is the minimum range for the y-axis?
0 to 900
0 to 250
0 to 10
65 to 250

0 to 900

Step-by-step explanation:

The three ordered pairs, (0, 250), (5, 575), and (10, 900) for the equation,

y = 65x + 250

imply that the y-axis should range from 0 to 900. The y-values from the ordered pairs are; 250, 575 and 900

a. is correct

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!
