Answer:
2
Step-by-step explanation:
Range is the highest number of plots minus the lowest number, in this case it would be 3-1
Replace the variable x with -4 in the expression.
f (- 4) = 3(- 4)^2 - (- 4) + 23
Simplify each term.
f (- 4) = 48 + 4 + 23
Simplify by adding numbers.
f (- 4) = 75
The final answer is 75.
You would do 2x+1=x-3 minus x from one side then follow the regular equation
1) 15 = 5(x + 2)
15 = 5x + 10
15 - 10 = 5x + 10 - 10
5 = 5x
5/5 = 5x/5
1 = x
2) 5n + 34 = -21(1-7n)
5n + 34 = -21 + 147n
5n + 34 = -21 + 147n
5n - 147n + 34 = -21 + 147n - 147n
-142n + 34 = -21
-142n + 34 - 34 = -21 - 34
-142n = -55
-142n/-142 = -55/-142
n = 55/142
