36 is what I got for this question
Answer:
x = -9.8
Step-by-step explanation:
6(x+7.8) =−12
Divide each side by 6
6/6(x+7.8) =−12/6
(x+7.8) =−2
Subtract 7.8 from each side
x+7.8-7.8 = -2-7.8
x = -9.8
So (x, y) and origin is is (0, 0) then you place three points on the graph, they should be as follows [(-9, -10), (0, 0), (9, 10)]. Count the spaces you moved from point a to point b, should be right 9 and up 10. meaning...
Slope = 9/10
I'm pretty sure this is correct, I hope this helped.
A) the equation accuretly models this scenario because Emanuel has a total of 48 cards. He bought some (X) and his aunt gave him 18. In order to find the number of cards he bought you set the number of cards he bought and the number of cards he got from his aunt equal to the number of cards he has.
B) 48= X + 18
Subtract 18 over
30=X
He bought 30 cards from the store.
48+ 30+18
