Answer:
x = 1
y = 5
Step-by-step explanation:
x + y = 4 __ (1)
2x + y = 3 __ (2)
equation (1) x 2, (2) x 1
2x + 2y = 8
2x + y = 3
 0  + y = 5
y= 5 (ANS)
x + y = 4
x + 5 = 4
x = 5 - 4
x = 1 (ANS)

Answer:
-	Right Angle Triangle – A Right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry (opposite, hypotenuse, adjacent).
-	Obtuse Triangle – An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles.
-	Acute Triangle – An acute triangle is a triangle with three acute angles (less than 90°).

Answer:
5088
Step-by-step explanation:
The initial value  of the car is $19340
The rate of decrease is 12.5%
The value of the car after 10 years is given by

Substitute the values to get;




To the nearest dollar we have $5088

Answer:
y = 2x
Step-by-step explanation:
Let's first find the slope:
m = (y₂ - y₁)/(x₂ - x₁)
m = (6 - 4)/(3 - 2) = 2/1 = 2
Now let's use point-slope form:
y - y₁ = m(x - x₁)
(For x₁ and y₁, you can use either (2,4) or (3,6), but I'm gonna use (2,4))
y - 4 = 2(x - 2)
y - 4 = 2x - 4
y = 2x
That's your answer.
Hope this helps, and hope you learned something!
