Answer:
growth
Step-by-step explanation:
This is of the form
y = ab^x where a is the initial value and b is either growth or decay
if b > 1 then it is growth
b <1 it is decay
a = .2
b = 4
Since b>1 it is growth
Answer:
adding both equations
4x+9y=5
-4x+7y=11
+ + =+
________
0 +16y=16
y=1
putting the value of y in first eqn
4x+9×1=5
4x=5-9
4x=-4
x=-1
so the x is -1 and y is 1
If you would like to solve the system of equations 2x + y = -4 and y = 3x + 2, you can do this using the following steps:
<span>2x + y = -4
y = 3x + 2
</span>_________
<span>2x + y = -4
</span>2x + 3x + 2 = -4
5x = -4 - 2
5x = -6
x = -6/5
y = 3x + 2 = 3 * (<span>-6/5) + 2 = -18/5 + 10/5 = -8/5
</span>
(x, y) = (-6/5, -8/5)
The correct result would be (-6/5, -8/5).
