The exponential function that approximates the amount of money in her account using a weekly growth rate is:
<h3 />
What is an exponential function?
An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal
In this problem, the yearly function is:
Considering that a year has 52 weeks, we have that:
0.06/52 = 0.001154
Hence:

-2y = 48 + 6x
-6x - 2y = 48 ——(1)
-6x + 9y = -84
-6x = -84 -9y ——(2)
Substitute (2) into (1):
(-84 -9y) -2y = 48
-84 -9y -2y = 48
-84 -11y = 48
-11y = 48 + 84
-11y = 132
y = - 12
Substitute y = -12 into (1):
-6x -2(-12) = 48
-6x + 24 = 48
-6x = 48 -24
-6x = 24
X = -4
ANS : y= -12, x= -4
Answer:
4.75x + 14.40y ≥ 700
Step-by-step explanation:
Given:
Plant cost = $4.75
Shrub cost = $14.40
Number of plant = 80
Number of shrub = 25
Total cost = $700
Find:
Inequality
Computation:
Number of plant = x
Number of shrub = y
4.75x + 14.40y ≥ 700
