In the store, the necklace will cost $140.25. This is because we are taking the price of 85$ and adding on an extra 65% of it to the number.
85(1.65) = 140.25
This is point slope form so you start with
y-b = m(x-a)
then you would find a point (5, - 1)
then fill in
y-5 = 3(x-1)
then if you want solve it for slope intercept form
y = 3x + 2
graph that and check your work
Answer:
+5x+6.
Step-by-step explanation:
Here you can use the foil method.
1. Multiply x by x to get
.
2. Multiply x by 3 to get 3x.
3. Multiply 2 by x to get 2x.
4. Multiply 2 by 3 to get 6.
Now, you have to add all those terms to get
+3x+2x+6 and you can simplify that to
+5x+6.
