Answer:
<em>-21 and 4</em>
Step-by-step explanation:
They multiply to a negative number, so you need a positive number and a negative number.
Answer:
A) car 1: exponential
car 2: linear
B) car 1: 
car 2: 
C) Yes, there will be a significant difference of $1,100.40 which is approx 10% of the value of the cars after 10 years.
Step-by-step explanation:
<u>Part A</u>
Car 1: exponential as the projected value is not decreasing by the same amount each year
Car 2: linear as the projected value decreases by the same amount each year ($1000)
<u>Part B</u>
<u>Car 1</u>
General form of exponential function: 
a = initial value = 18500
b = growth factor = 

NB We have to change x to "x-1" since we are told in the table that <u>after</u> 1 year the car's value is 18500.
<u>Car 2</u>
General form of linear function: 




<u>Part C</u>
Car 1 after 10 years: 
Car 2 after 10 years: 
Difference = 10600.40 - 9500 = 1100.40
Yes, there will be a significant difference of $1,100.40 which is approx 10% of the value of the cars after 10 years.
Look at the picture.
We have the equation (1) 12x + 4y = 40.
We know, the sum of the acute angles in a right triangle is 90°.
Therefore we have the equation (2) (12x + 4y) + (17x - y) = 90
Substitute (1) to (2):
40 + 17x - y = 90 <em>subtract 40 from both sides</em>
17x - y = 50 (3)
We have the system of equations:

Substitute the value of x to (3)

Answer: x = 3 and y = 1.
Answer:
yes
Step-by-step explanation:
A proportional equation is of the form
y = kx where k is the constant of proportionality
y = 150x is proportional
