As soon as a new car is purchased and driven away from the dealership, it begins to lose its value, or depreciate. Alonso bought a 1994 Plymouth Neon for $9559. One year later, the value of the car was $8500. What was the percent of decrease of the value of the car?

P.S. This is a percent increase/decrrease
from: 9559
to: 8500

%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)

Step-by-step explanation:

when perpendicular, u must use m1m2=-1

so , (⅓)(m2)=-1

m2= -3

y-y1=m2(x-x2)

y-1=-3(x-0)

y=-3x+1

Answer:

y = -3x + 1

Step-by-step explanation:

to be perpendicular the multiplication of the gradiens should be -1

m1 × m2 = -1 , m1 = 1/3

1/3 × m2 = -1

m2 = -3

and required equation passes through the point.( 0,1)

y = m2 x + c2

1 = -3 (0) + c2

c2 = 1

so the equation

y = -3x + 1

Answer:

6.8

Step-by-step explanation:

This sounds super complicated, but all it is asking is 1.3 + 5.5, which equals 6.8.

Answer:

Step-by-step explanation:

Considering the functions

[tex]f(x) = 5x + 4[/tex]

[tex]g(x) = x - 3[/tex]

Part 1)

Find

We need to first dertermine [tex]g(6)[/tex]

[tex]g(x) = x - 3[/tex]

Putting x = 6

[tex]g(6) = 6-3=3[/tex]

Then

[tex]f(g(6))=f(3)=5(3)+4=15+4=19[/tex]

Hence,

[tex]f(g(6))=19[/tex]

Part 2)

Find

We need to first dertermine [tex]f(-7)[/tex]

[tex]f(x) = 5x + 4[/tex]

Putting x = -7

[tex]f(-7) = 5(-7)+4=-35+4=-31[/tex]

Then

[tex]g(f(-7))=g(-31)=(-31-3)=-34[/tex]

Hence,

[tex]g(f(-7))=-34[/tex]

Part 3)

Find

We need to first dertermine [tex]f(8)[/tex]

Putting x = 8

[tex]f(8) = 5(8)+4=40+4=44[/tex]

Then

[tex]f(f(8))=f(44)=5(44)+4=220+4=224[/tex]

Hence,

[tex]f(f(8))=224[/tex]

Part 4)

Find

[tex]f(x) = 5x + 4[/tex]

[tex]g(f(x))=g(5x+4)[/tex]

         [tex]=(5x+4)-3=5x+1[/tex]

Hence,

[tex]g(f(x))=5x+1[/tex]

Answer:

x=17

Step-by-step explanation:

7x+15=4x+66

3x=51

x=17

Answer:

17

Step-by-step explanation:

7x + 15° =  4x + 66° (vertically opposite angles are equal)

7x - 4x = 66 - 15

3x = 51

x = 51/3

x = 17

Answer:

d+2.5+d-4

Step-by-step explanation:

Answer:

Step-by-step explanation:

The two integers are 10 and 9

10 + 9 = 19

10 x 9 = 90

The two numbers are 9 and 10.

A number without a decimal or fractional element is known as an integer, which can be both positive and negative, including zero

Let the two integers be x and y.

Given that, the sum of the integers is 19, therefore,

x + y = 19

x = 19 - y

Given that, the product of the integer is 90:

xy = 90

(19-y)y = 90

19y - y² = 90

y² -19y + 90 =0

y² -10y - 9y + 90 = 0

y(y - 10) -9(y - 10) = 0

(y -9)(y - 10) = 0

y = 9 and y = 10

Hence, the two numbers are 9 and 10.

Answer:

P

Step-by-step explanation:

P tells us that the Domain: 3,-1,4,2 doesn't repeat

Q does repeat its Domain: 7,5,-1,5

Reminder that in order for a line of ordered pairs to be a function the domain number Shouldn't repeat, That doesn't mean that the range cant repeat.

Example: (5,-3), (5,9) Not a function

                (-1,-6), (7,-6) Function

Out of the two set given, the set of ordered pairs that represents a function is: P = {(3, 5), (−1, 5), (4, −6), (2, 9)}.

A set of ordered pairs that has one exact y-value assigned to each x-value is considered a function.

In set P, all x-values has exactly one y-value, while in set P, the x-value, 5, has two different y-values, 9 and -3.

Therefore, the set of ordered pairs that represents a function is: set P.
