Choose the constant term that completes the perfect square trinomial.

1 answer:

3 0

A perfect trinomial, if we begin by a binomial is defined as: the square of the first term, plus (or minus) the double product of the first term times the second, plus the square of the second term:
(a + b)^2 = a^2 + 2ab + b^2
We are given:
y^2 + 5y + x
we need to find x, so x is defined as a squared quantity, which is equal to the second term coefficient (5) divided by 2, and that number squared, that is:
(5/2)^2 = 25/4
that is the third term for the trinomial to be perfect.

Pizzas are being delivered. It cost $9 for 2 pizzas including delivery. Each pizza cost $4. Please solve in Point-Slope form!

hjlf

The equation representing pizza purchase and delivery in point slope form is y = 2x + 1 and the delivery fee is $1

The total cost of pizza including delivery can be broken down thus :

Cost per pizza
Number of pizza purchased
Delivery fee (this is a constant)

General form of a point slope equation :

y = a + bx
y = total cost
a = intercept (Constant)
b = slope(cost per pizza)
x = number of pizzas purchased

From the question :

Total cost including delivery = $9 = y
Cost per pizza = $4 = b
Number of pizzas = 2

Putting the values into the equation :

9 = 4(2) + a

Solve for a

9 = 8 + a

9 - 8 = a

a = 1

This means that delivery fee is $1

The equation in point slope form is thus : y = 2x + 1

Find the difference vertically.

Daniel [21]

$-a^{5} - ( b^{2} + a^{2} b^{2} )-( -a^{5} - a^{2} b^{2} ) 



 
$
$-a^{5} + (- b^{2} - a^{2} b^{2}) + ( a^{5}+ a^{2} b^{2} )$

$-a^{5} + 0 +0
$
$a^{5} + a^{2} b^{2} +0$
$0 + -a^{2} b^{2} - b^{2}$

The answer would be: $- b^{2}$
