Answer:1/16
Step-by-step explanation:
So I plugged in -4 for x
f(x)=2^-4= 1/16
hope that helps
<span>You are given a a graph titled Plant Height that shows Number of Weeks on x axis and Height of Plant in cm on y axis. Plotting this and you will get an equation of y = 1.2792x - 0.1665 (I used excel using the given points from the above problem).
</span>y = 1.2792x - 0.1665
y = 1.2792 (7) - 0.1665
<span>y = 8.78 centimeters.
The most likely approximate height of the plant after 7 weeks is 8.7 centimeters.

Answer:
The answer for the question "What is the constant of proportionality?" is 2.
The answer for the question "If Micah saves $150, How much money will his parents give him?" is $300.
Step-by-step explanation:
a. If for every $5, Micah will receive $10 more that means that he will receive the double of his initial saving. So, a number that multiplied by 5 is equal to 10 is 2. Therefore, the proportionality equation will be Y=2X, where Y is 10 and X is 5. In cunclusion, 2 is the constant of proportionality.
b. Having in mind that the equation is Y=2X, and that X is equal to Micah's savings, we need to replace that X with 150. Then, 150 is multiplied by 2 and the result is Y, in this case 300. So, Micah's parents will give him $300 if he saves $150.
Answer:
x =5, y = 22
Step-by-step explanation:
5y + 79 + 5y + 61 = 360
10y = 220
y = 22
2x + 7 = 4x - 3
-2x = -10
x = 5
