Answer:
(3, -2)
Step-by-step explanation:
To find the vertex, put the equation into vertex form by completing the square
2(x^2 - 6x) + 16 [pulling out the 2]
2(x^2 - 6x + 9) - 18 + 16 [completing the square, you subtracted 2*9 = 18 so you also add 18]
2(x - 3)^2 - 2 [simplify the equation]
vertex is (3, -2)
You add all the numbers then divide by the amount of numbers. The answer is 246.3636
Answer:
y = 0.5x - 3
Step-by-step explanation:
Using (6,0) and (0,-3)
y- intercept is clearly -3
Slope: (-3-0)/(0-6) = -3/-6 = 0.5
y = 0.5x - 3
Answer: Additional interest of $521.82 with a simple interest loan to sister generate.
Step-by-step explanation:
Since we have given that
Principal = $28000
Rate of interest at simple interest = 8%
Number of year = 1
so, Interest becomes,

Rate of interest compounded quarterly = 6%
Amount becomes,

So, Interest would be

Hence, Additional interest is given by

Hence, Additional interest of $521.82 with a simple interest loan to sister generate.
Answer:
x=9
Step-by-step explanation:
2/3x-1=5
Add 1 to each side
2/3x-1+1= 5+1
2/3x = 6
Multiply each side by 3/2
2/3x*3/2 = 6*3/2
x = 9
