Substitute x=3 and y=5 into the X and y given
2(3*3*3)+2(5(3)+(5*5))-(3+5)
2(27)+2(15+25)-8
54+2(40)-8
54+80-8=126
Hope it helps.

First, solve for the slope. This can be found by looking at the y and x intercepts. At x = 0, y = 1.5. At x = 2, y = 0.

Slope is defined as Δy/Δx, or the change in y over the change in x. This means that in order to calculate the slope, you must find the difference between the values of y and divide it by the difference in the values of x for the two points to determine the slope between them.

(0 - 1.5)/(2-0) = (-1.5)/2 = -0.75 or -3/4

Now that you have the slope, we can write the equation in slope intercept form, y = mx + b, where m is the slope we calculated and b is the y intercept, 1.5.

y = (-3/4)x + 1.5

QUESTION 1

Answer 1
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r)^(n)-1)÷r]
Solve the formula for n
Fv/pmt=(1+r)^(n)-1)÷r
cross multiplication
(Fv/pmt)×r=(1+r)^(n)-1
(Fv/pmt)×r+1=(1+r)^(n)
take the log for both sides
Log ((Fv/pmt)×r+1)=n×log (1+r)
Divide each side by log (1+r)
N=[Log ((Fv/pmt)×r+1)]÷log (1+r)
Now solve to find n
N=log((10,000÷800)×0.03+1)
÷log(1+0.03)=10.77years round your answer to get 11 years
