Equation 5d + 8 = 14 + 3d has o
Answers
Answer:
d = 3
Step-by-step explanation:
Isolate the variable, d. Note the equal sign, what you do to one side, you do to the other. Subtract 8 and 3d from both sides:
5d (-3d) + 8 (-8) = 14 (-8) + 3d (-3d)
5d - 3d = 14 - 8
2d = 6
Divide 2 from both sides:
(2d)/2 = (6)/2
d = 6/2
d = 3
d = 3 is your answer.

Answer:
a) The portfolio will be at maximum after 12 months (1 year)
b) The maximum value of the portfolio is $5432
Step-by-step explanation:
The function that models Jennifer's stock portfolio (in dollars) is , where t is the time in months since she opened the account.
We complete the square to obtain this function in vertex form:
Factor -3 from the first two terms
.
Add the zero pairs -3(+144),-3(-144)
.
Factor the perfect square trinomial and simplify.
.
The vertex of this function is (h,k)=(12,5432)
a) The portfolio will be at maximum when t=12, the h-value of the vertex
b) The maximum value of the portfolio is the k-value of the vertex which is 5432

What is equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
given that,
equation: 1
4x+3y=16
y=(16-4x)/3
equation: 2
7x+6y=31
y=(31-7x)/6
now, we have,
(16-4x)/3 = (31-7x)/6
6(16-4x) = 3(31-7x)
96-24x=93-21x
3=3x
x=1
we get,
4x+3y=16, x=1
4(1)+3y=16
4+3y=16
3y=12
y=4
so, we have,
x=1, y=4
therefore the answer is B (1,4)

y=(16-4x)/3 y=(31-7x)/6
(16-4x)/3 = (31-7x)/6
6(16-4x) = 3(31-7x)
96-24x=93-21x
3=3x
x=1
4x+3y=16, x=1
4(1)+3y=16
4+3y=16
3y=12
y=4
x=1, y=4 therefore the answer is B (1,4)
