You just need to substitute the the given function. So if f(-8) then you fill in f(n)=2n+4 which would be f(-8)=2(-8)+4. Which is -12.
hope this helps !

Answer:
133.33g
Step-by-step explanation:
Let the:
Mass of 1.2g/cm³ of liquid = x
Mass of 1.8g/cm³ of liquid = y
From our Question above, our system of equations is given as:
x + y = 400........ Equation 1
x = 400 - y
1.2 × x + 1.8 × y = 1.6 × 400
1.2x + 1.8y = 640..... Equation 2
We substitute, 400 - y for x in Equation 2
1.2(400 - y) + 1.8y = 640
480 - 1.2y + 1.8y = 640
- 1.2y + 1.8y = 640 - 480
0.6y = 160
y = 160/0.6y
y = 266.67 g
Solving for x
x = 400 - y
x = 400 - 266.67g
x = 133.33g
Therefore, the mass of the liquid of density 1.2g/cm³ is 133.33g
In an hour there are 60 minutes.
6:38 PM + 22minutes = 7 PM
From 7 PM to 7:23 PM there are 23 minutes
So, (23 + 22) minutes = 45 minutes.
Answer:
Choice A
Step-by-step explanation:
Choice A: $1.49/6 oz = $0.248/oz
Choice B: $3.59/13 oz = $0.276/oz
Therefore, Choice A is the lower price per ounce.
