Answer:
x = 3
Step-by-step explanation:
3(2 - 4x) = -30
=>6 - 12x = -30
=> 12x = 36
=> x = 3
Answer:
x= -15
Step-by-step explanation:
Answer:
y=3x+21
Step-by-step explanation:
Use slope intercept form and plug in the numbers
y=mx+b
-5 is x, 6 is y and m is 3.
6=3(-5)+b
6=-15+b
6+15=b
b=21
Now plug in the b.
y=3x+21
An exponential increase may be represented as y = A(B^x).
You can find the parameters A and B using the initial condition and the value after 2 years.
1) Initial condition: x = 0 => y = 500 => 500 = A(B^0) = A(1) = A => A = 500 => y = 500 (B^x)
2) After 2 years y = 500 (B^2) = 551.25 => (B^2) = 551.25 / 500 = 1.1025 => x = sqrt(1.1025) = 1.05.
Then A = 500 and B = 1.05 => x = 500 (1.05)^x.
