To calculate any speed, the equation is speed=distance/time
Basically, you first need to take your 9 hours and 15 minutes and combine them into a number with a decimal value.
So, 15*4=60
Sound familiar? Good, because 25*4=100, so they are the same here.
So, we can say 9 hours and 15 minutes is equal to 9.25
Take this now: Speed=538/9.25
You get 58.1621, which you can round to 58.2
This is, of course, your final answer, so Joe drove at 58.16 mph

Answer:
x = 1.5
Step-by-step explanation:
To get the vertex of a quadratic equation you can use the formula
x = -b/2a
where f(x) = ax² + bx + c
So you would get -12/2(-4)
-12/-8
x = 1.5
Then substitue x in the equation to find y. I won't be doing that here

Step-by-step explanation:
The required system hence becomes
3x-y+4>0,
y + 6 > (x + 2)²
When the symbols “>”, “<”, “≥”, “≤”, are used to connect two real numbers or algebraic expressions, that relationship is known as an inequality.
The Graph is given below of the given problem statement.
Observe that the parabola y=x² has vertex at (0,0) we can shift the vertex to (-2,-6) to get the parabola
y + 6 = (x + 2)²
And the inequality is
y + 6 > (x + 2)²
Hence, this parabola is as required by the problem.
And the line passing through (-3,-5) and (0,4) is
The required inequality hence becomes
3x-y+4>0
