Answer:
b. y = -7x + 4
1. y = -7(-5)+ 4 = 35+4= 39
2. -24= -7x + 4
-28 = -7x
4 = x
3. y = -7(0)+4= 4
4. 0 = -7x+4
-4= -7x
4/7 = x
c. 3y - 5x = 15
1. 3y - 5(6)
3y-30=15
3y=45
y = 15
2. 3(-10)-5x=15
-30-5x=15
-5x = 45
x = -9
3. 3y-5(0)=15
3y=15
y=5
4. 3(0)-5x=15
0-5x=15
-5x=15
x=-3
Step-by-step explanation:
The answer will be 2(x+3)
Answer:
speed=200 m/s
Step-by-step explanation:
Answer:
$220,000 represents the initial cost of a real estate that appreciates 3% per year over the course of t years.
Step-by-step explanation:
Equation for a real estate value:
Where V(t) represents the value of the real estate
t represents the time in years.
Exponential growth equation:
Exponential decay equation:
The given Equation for a real estate value can be written as :
Om comparing with growth and decay equations
We conclude that it is the growth equation
Where r = 0.03 =3%
a=Initial cost = 228000
So, Option B is true
$220,000 represents the initial cost of a real estate that appreciates 3% per year over the course of t years.
