(0,-6), (6, -3), and (6,-6)

If you plot them on a graph there are only two point options (in green and purple) since it's a right triangle but you have to use the one that has -6 as the y value

If using the method of completing the square to solve the quadratic equation x^2-5x-18=0x 2 −5x−18=0, which number would have to
MAVERICK [17]

Answer:

25/4 will have to be added to "complete the square"

Step-by-step explanation:

x² - 5x - 18 = 0

x² - 5x = 18

Find the half of the coefficient of x and square it

(5/2)² = 25/4

Add 25/4 to both sides to complete the square

x² - 5x + 25/4 = 18 + 25/4

x² - 5x + 25/4 = 18(4/4) + 25/4

x² - 5x + 25/4 = 72/4 + 25/4

x² - 5x + 25/4 = (72+25)/4

x² - 5x + 25/4 = 97/4

(x - 5/2)² = 97/4

Find the square root of both sides

√(x - 5/2)² = ±√97/4

x - 5/2 = √97/2

x = √97/2 + 5/2 or x = -√97/2 + 5/2

x = 7.42443 or -2.42443

A man walks 10 miles in x hours. How far does he walk in one hour?
Andreas93 [3]

Answer:

Option  (c) is correct.

The distance covered by the man in 1 hour is represented by te expression  \frac{10}{x} miles.

Step-by-step explanation:

Given: A man walks 10 miles in x hours.

We have to choose a correct  expression that represents the distance covered by the man in 1 hour.

Consider the given statement."A man walks 10 miles in x hours."

Using UNITARY METHOD,

(is a method in which we first find the value of a single unit and then multiply it with desired quantity)

Distance covered by man in x hours = 10 miles,

So distance covered by man in 1 hour = \frac{10}{x} miles.

So, The distance covered by the man in 1 hour is represented by te expression  \frac{10}{x} miles.

An account earns simple interest.
olasank [31]
Data:
P (Principal) = $1500
I (Simple Interest) = ?
t (time) = 5 years 
r (percentage rate) = 4% = 0.04

Formula:
I = P*r*t

Solving (1) <span>Find the interest earned.</span>
I = P*r*t
I = 1500*0.04*5
\boxed{\boxed{I = 300}}\end{array}}\qquad\quad\checkmark

Solution (2) <span>Find the balance of the account.
</span>The future value, (Account), of a loan is given by the equation: A = P + I
A = P + I
A = 1500 + 300
\boxed{\boxed{A = 1800}}\end{array}}\qquad\quad\checkmark
