How do I graph y+x= -3
Nitella [24]

Answer:

Use Desmos.com/calculator

Step-by-step explanation:

Remember, y=mx+b

y is equal to any given y point

x is equal to any given x point

m is equal to slope

b is equal to the y-intercept, or where x = 0 and the line crosses the horizon line.

In order to graph the line correctly, you have to isolate y.

y+x=-3

y=-x-3 would be equal to y=mx+b format

slope is negative 1

y intercept is negative 3

start on the y line, go to (0,-3) and start your line.

slope is negative 1, so you go down one and right one.

3) Lane and Zack purchased a house for $245,000 in 2016. The house loses 4% of its value each year,
alina1380 [7]

Answer:

$138,345

Step-by-step explanation:

This is a compound decline problem, which will be solve by the compound formula:

F=P(1-r)^t

Where

F is the future value (value of house at 2030, 14 years from  2016)

P is the present value ($245,000)

r is the rate of decline, in decimal (r = 4% = 4/100 = 0.04)

t is the time in years (2016 to 2030 is 14 years, so t = 14)

We substitute the known values and find F:

F=P(1-r)^t\\F=245,000(1-0.04)^{14}\\F=245,000(0.96)^{14}F=138,344.96

Rounding it up, it will be worth around $138,345 at 2030
