-3t-15+5t+3=8
2t-12=8
2t = 20
t = 10
Answer:
Step-by-step explanation:
Let's assign each person a variable using the first letter of his/her name.
Then we get the following equations based on the information given:
Then we can use substitution:
Rearrange the second equation:
Multiple the equation by 3:
Combine the equations to solve for a single variable (L):
Then we have a new equation:
Use substitution to get the rest:
The correct answer is D, 146 inches.
7 x 12 = 84
4 x 12 = 48
84+48+4+10 = 146
Answer:
Domain: [-6, 6]
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function <em>g</em>.
We see from the graph that our x-values span from -6 to 6. We also see that both points are also closed dots, so we use brackets to denote that they are included. Therefore, [-6, 6] would be our domain.
