We have that
y = 3x²<span>+ 2x + 1

step 1
</span>

Group terms that contain the same variable, and move the constant to the opposite side of the equation

y -1= (3x²+ 2x)

step 2

Factor the leading coefficient

y -1= 3*(x²+ 2/3x)

step 3

Complete the square. Remember to balance the equation by adding the same constants to each side

y -1+(1/3)= 3*(x²+ (2/3)x+(4/36))

y-2/3=3*(x+2/6)²

the vertex is the point (-2/6, 2/3)------> (-0.33,0.67)

the answer is

(-0.33,0.67)

What is the value, after 7 years, of a 2014 Ford Mustang that originally costs $25,000.00 if it depreciates at a rate of 8% per
Sholpan [36]
The value would be $14,000.

The formula we use for this is

A = p(1+r)ˣ, where p is the initial value, r is the percent of depreciation (as a decimal number) and x is the number of years.  Note that since it is depreciation, r will be a negative number.

A = 25000(1-0.08)⁷ = 13946.17 ≈ 14000

{(4z-7,z-4,z) |z is any real number} z=-5
weeeeeb [17]

The set when z = -5 is {-27, -9, -5}

<h3>How to determine the set elements?</h3>

The set is given as:

{(4z-7,z-4,z) |z is any real number}

When z=-5, we have:

4z - 7 = 4(-5) - 7 = -27

z - 4 = -5 - 4 = -9

z = -5

So, we have:

{(4z-7,z-4,z) |z is any real number} ⇒ {-27, -9, -5}

Hence, the set when z = -5 is {-27, -9, -5}
