You have the following function:
g(x) = 3x - 7
In order to determine th value of x when g(x) = -4, you equal the previous expression to -4 and solve for x, just as follow:
g(x) = 3x - 7 replace g(x) = -4
-4 = 3x - 7 add 7 both sides
-4 + 7 = 3x simplify
3 = 3x divide by 3 both sides
3/3 = x
x = 1
Hence, the anser is x = 1
Answer:
An equation:
Step-by-step explanation:
Let h be the number of hours and C be the total number of charges.
As per the statement: Nila charges customers by $2 per hour.
"$2 per hour" means 2h
Since, Fixed cost = 0
Variable cost = 2h
Then;
Therefore, an equation should she now use to determine how much to charge her customers is,
Total miles = 70 + 70 = 140 miles
Total time = 140 miles / 57 mph = 2.456 hours
Time 1: 70 miles / 70 mph = 1 hour
Time 2: 70 miles / x mph
Total time = time 1 + time 2:
2.456 = 1 hour + 70/x
Subtract 1 hour from both sides:
1.456 = 70x
multiply both sides by x:
1.456x = 70
Divide both sides by 1.456:
x = 70/1.456
x = 48.0769 miles per hour
Rounded to 2 dp = 48.08 miles per hour
