Wally buys a baseball card for $5, sells if for $6, buys the same card back for $7 the following days, and then resells it for $8. How much profit or loss occurred in all these transactions combined?

3 dollars profit

Step-by-step explanation:

if he has $5 b-card and sells it for $6 he gains a dollar. But if he buys it back for $7 then he lost $2 from his original price. In the end, he sells it for $8 so he gains a $3 profit. 8 - 5 = 3

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
