Answer:
Step-by-step explanation:
(2x+6)/5=2y,
½(2x+6)/5=y,
(x+3)/5=y, so y=(x+3)/5.
Answer:
investment in cd = x = $50000
investment in mutual funds = $ 25000
return = $5000
Step-by-step explanation:
let x be the investment in CD
let y be in mutual fund
from the data given we have
Return = 6% x + 8% y
Return = 0.06 x + 0.08 y
plotting these three inequalities on graph we have critical number as
(16000, 8000) : return = 0.06 (16000 + 0.08 (8000) = $1600
(50000, 25000) : return = 0.06 (50000) + 0.08 (25000) = $5000
(67000, 8000) return = 0.06 (67000) + 0.08(8000) = $4660
As we can see maximum benefit is $5000 so we have
investment in cd = x = $50000
investment in mutual funds = $ 25000
return = $5000
E= -4 when the problem is simplified
Answer: x=-1
Step-by-step explanation:
the x value of the vertex = -b/2a if the equation is in "ax^2+bx+c" for
you are in luck
x value of the vertex = -4/4 = -1
the line of symmetry is a vertical line, and since it must pass through the vertex
line of symmetry: x=-1
