15x^2 - 16xy + 4y^2

We can convert this trinomial into a quadrinomial, as it currently does not have any shared factors.

After viewing factors of 60 (15 * 4 = 60) we can determine that the numbers -6 and -10 satisfy the criteria.

The trinomial is now:

15x^2 - 6xy - 10xy + 4y^2

Now, we can factor each binomial.

3x(5x - 2y) - 2y(5x - 2y)

Simplify.

(3x - 2y)(5x - 2y) is the fully factored form of the provided polynomial.

Answer the photo below thanks Question: What is the value of x in the diagram.

kaheart [24]

Answer:

A. X = 30º

Step-by-step explanation:

The angle labeled x & the right angle are vertical angles to the one labeled 120º.

Therefore:

X + 90 = 120

Solve for x:

X + (90-90) = 120 - 90

X = 30

Hope this helps! Have a great day!

Answer:

$y=-3,250t+25,000$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope of unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

Let

t ----> the number of years since 2011

y --->the car's value

In this problem the year 2011 represent t=0

the year 2015, represent t=4 years (2015-2011)

we have the ordered pairs

(0,25,000) ----> represent the y-intercept

(4,12,000)

Find the slope m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{t2-t1}$

substitute the values

$m=\frac{12,000-25,000}{4-0}$

$m=\frac{-13,000}{4}$

$m=-\$3,250\ per\ year$ ---> is negative because is a decreasing function

we have

$b=\$25,000$ ----> value of y when the value of x is equal to zero (initial value)

substitute the given values

$y=-3,250t+25,000$
