Let's say the point is C, so C partitions AB into two pieces, where AC is at a ratio of 3 and CB is at a ratio of 7, thus 3:7,

Interest rate = 7%
I= PRT where I is the interest earned, p is the principal, r is rate as a decimal, and t is time in years.
A - P will give us the interest earned.
12,150 - 9,000 = 3,150
3150 = (9000)(r)(5)
3150 = 45,000r
r = 0.07
r = 7%
Answer:
false
Step-by-step explanation:
it suppose to be -2 if you equate it to Zero
Could you be a little more specific.
Add 8 to both sides
3x=33
Divide both sides by 3
x=11
