Answer:
4; y-5=2(x+3)
Step-by-step explanation:
Question 1: 8y-18=14
8y=32
y=4
Question 2: y-5=2(x-(-3)
y-5=2(x+3)
19y-9 is a simpler form of this expression. You can use distributive property to get rigid the brackets (multiply -3 by -4y and 3) , then your expression looks like 12y-9+7y. You then combine like terms to get 19y-9.
The formula for compound interest is:

Given data:

a. After ten years, that is t = 10 years, the amount in the account will be

b. After twenty years, that is t = 20 years, the amount in the account will be:

c. The time it takes for Harry's initial account value to double will be:

Therefore, the time it takes Harry's initial account to double is approximately 11 years
Here the graph y=x²
Taking the 1st derivative here of the y it will be
y1 = 2x
m=-1/3
That is m=2x
so x=-1/6
so y=(-1/6)²=1/36
So the coordinate of point will be=(-1/6 , 1/36)
