y=1/3x-1

We know straight away that the y intercept is -1 from the equation.

y-intercept: (0,-1)

To find the x intercept plug in 0 for y in the equation.

y=1/3x-1

0=1/3x-1

1/3x=1

x=3

x-intercept: (3,0)

answers: y-intercept: (0,-1) and x-intercept: (3,0)

Item 1 The value of a car is $23,000. It loses 11.1% of its value every year. Find the approximate monthly decrease in value. Ro

IrinaK [193]

Answer:

Step-by-step explanation:

If the car loses 11.1% per year, we need to calculate how much money is that:

$23,000\frac{11.1}{100} = 2,553.$ ; this value is the lost per year.

Now, in order to calculate this loss per month, we divide it by 12:

$\frac{2553}{12} =212.75$

Hence, the monthly value decrease is $212.8, rounding it to the tenth.

Which ordered pair is a solution of the system?

kenny6666 [7]

Y = -2x - 4

x + 4y = 19
x + 4(-2x - 4) = 19
x + (-8x) - 16 = 19
-7x - 16 = 19
-7x = 35
-x = 5
x = -5

y = -2x - 4
y = -2(-5) - 4
y = 10 -4
y = 6

Solution set {-5, 6} (C)
