The table with x=0, 1,2 y= 2,-1,-4
Answer:
{x| 43 ≤ x ≤ 47} where x = Sean's speed (in mph)
Step-by-step explanation:
Sean is taking driver's ed. The instructor asked him to stay within 2 miles of the posted speed limits. The current speed limit is 45 mph.
So, the maximum speed which Sean can reach is, (45 + 2) mph
=47 mph
and, the minimum speed which Sean can reach is, (45 - 2) mph
=43 mph
so, {x| 43 ≤ x ≤ 47} where x = Sean's speed (in mph)
Answer:
Step-by-step explanation:
Given
Required
f(10)
An exponential function is represented as:
impleies that:
--- (1)
implies that
--- (2)
Divide (2) by (1)
Take 4th root
Substitute in
Solve for (a)
f(10) is calculated as:
Answer:
$10.10
Step-by-step explanation:
$7.50 + $2.60 = $10.10
In your equation: a+(-4)=-13
you then add four to each side,
so a= negative 13 plus 4
so a= -9
