The answer to this question would be: <span>y=5x-1
To solve this question, you need to see what the value of Y when X=0. In this case, when X=0 the Y=-1
That means if the function is Y= AX+ C then the C would be:
Y= AX +C
-1= </span>A(0) +C
<span>C= -1
If you put the second equation where X=1 and Y=4 then
</span>Y= AX +C
4= A(1) -1
4= a-1
a=5
The answer would be y=5x-1

Answer:
The width of the actual pool is 12 meters
Step-by-step explanation:
You can put Kiara's scale into a ratio or fraction to help visualize it better: 13/6. Now, let's put what we do know for the other ratio into a fraction. we know that the pool is 26 centimeters wide, and since the 26 matches with the 13, that goes in the numerater. since we don't know the denominator, we can just put 26/x (you can use whatever letter you like but I'll use x here)
So in order to get 13/6 to 26/x, we need to find how to figure out what we are doing to the original fraction. Since 13 x 2= 26, it looks like we are multiplying the ratios by 2. Now that we know that, we can multiply the denominator (6) by 2 to equal 12, our answer.
Hope this helps :)
Answer:
142 years 3 months
Step-by-step explanation:
Let us assume the investment is made using a simple interest
Given data
Principal p= $1200
Rate r= 7.5%= 7.5/100= 0.075
Final amount A= $14000
Time t=?
The Simple interest formula is expressed as
A= p(1+rt)
Substituting we can solve for t
14000= 1200(1+0.075t)
14000= 1200+90t
14000-1200=90t
12800= 90t
t= 12800/90t = 142.22 years
The time required to get a total amount, principal plus interest, of $14,000.00 from simple interest on a principal of $1,200.00 at an interest rate of 7.5% per year is 142.22 years (about 142 years 3 months).
