Answer:
x = -1, y = -4
Step-by-step explanation:
Let's solve our system of equations by substitution.
y = 5x + 9y = −x + 3
Step: Solve = 5x + 9 for y:
y = 5x + 9
Step: Substitute 5x + 9 for y in y = −x + 3:
y = −x + 3
5x + 9 = −x + 3
5x + 9 + x = −x + 3 + x (Add x to both sides)
6x + 9 = 3
6x + 9 + −9 = 3 + −9 (Add -9 to both sides)
6x = −6
6x/ 6 = −6/6(Divide both sides by 6)
x = −1
Step: Substitute −1 for x in y = 5x + 9:
y = 5x + 9
y = (5)(−1) + 9
y = 4(Simplify both sides of the equation)
So our answers are y = -4 and x = -1.
First, figure out its slope. that is (4-2)/(2-1)=2
then, write its point-slope form:
y-(-3)=2(x-2)

Answer:
$1,700
Step-by-step explanation:
The answer is $1,700. To solve the problem, we have the change 15% into a decimal which would be (.15). Then we multiply 2,000 by (.15) which is shown below.
(2,000) x (.15) = 300
300 is the amount the car has depreciated. The new value of the car is found by subtracting 300 from 2,000.
2,000 - 300 = 1,700
The car value is now $1,700.
