F(x)= 2(4)-12
F(x)= 8-12
-4 is the answer
The numerical expression that describes the amount of time it takes Imani to walk to school is x = 5y - 1.
<h3>How do we derive a numerical expression?</h3>
Let:
x = amount of time it takes Imani to walk to school
y = amount of time it takes Imani to ride to school = 3 minutes
The numerical expression that describes the amount of time it takes Imani to walk to school can be written as follows:
x = 5y - 1
Since it takes Imani three minutes to ride her bike to school, we can solve for x by substituting y = 3 as follows:
x = (5 * 3) - 1 = 15 - 1 = 14 minutes

B. Lipid because it contains Fatty Acid And Glycerol
Answer: y= 5/4 + 3/2
Step-by-step explanation: Your equation is y=mx +b. You have to subtract the second y from the first y, and the second x from the first x to find the slope. This equation would be 4-(-1) over 2-(-2). So your slope will be 5/4. Now to find the y-intercept you can choose either (x,y) point. For example if you are using (2,4) you would do b= 4-(5/4)(2). b=3/2.
