First take the -10 and add it to 30 (10+30=40) then you have 5x=40. Then you want to isolate the x. So take 5 divided by both sides 40/5=8. I thin the answer should be 8. Where you trying to get the slope or find x?
5y<7 <------- That is the answer. BTW (by the way) the variable needs to always be on the rights side.
Hope this helps!!!!!!!!!
Because the slope doesn't tell you any actual points on the line.
It only tells you whether the line tilts up or down, and how steeply.
But the line could be way up there or way down under, with the same slope.
You can't actually DRAW it until you know some point on it, and
the y-intercept gives you one.
Answer:
The price that Camilla paid for the book was $9.
Step-by-step explanation:
To be able to find the pice that Camilla paid for the book, first, you have to calculate the 25% of the price of the book:
$12*25%=$3
Now, you have to subtract that amount from the price of the book:
$12-$3=$9
According to this, the answer is that the price that Camilla paid for the book was $9.
