Answer:???
Step-by-step explanation:
Answer:
The speed of the car is 42 miles per hour
Step-by-step explanation:
Step 1:
(Blank) x s = (Blank)
Let us evaluate this. Something times s miles per hour is going to gives us? 126 miles. So, our second blank would be 126 since that's our total:
(Blank) x s = 126
Step 2:
On the other hand, our first blank would be 3. Why? Because that's the amount of time it takes us to go 126 multiplied by s miles per hour; Our new equation is:
3 x s = 126
Step 3:
We can simplify this equation to:
3s = 126
Step 4:
We now have a one step equation. Divide each side by 3 to get s by itself.

Step 5:
We end up getting:
s = 42
That means that the car is traveling at 42 miles per hour. If the car continues at that rate for 3 hours, the car would have traveled 126 miles.
Hope this helps!
<em><u>x>23 is the correct answer.</u></em> First you had to subtract by 3 from both sides of equation. And it gave us,
. Then simplify, and it gave us,
. Next, multiply by 2 from both sides of equation, and it gave us,
. Then simplify, and it gave us,
. You can also subtract by 3 from both sides of equation, and it gave us,
. Then simplify, and it gave us,
. Multiply by -1 from both sides of equation, and it gave us,
. Finally simplify, and it gave us the answer is<u><em> x>23 is the right answer. </em></u>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
Answer: I believe it is 1.1x10^-8
Step-by-step explanation:
Because 3.4x10^2 divided by 3x10^10 gives you 0.00000011 which is then converted through scientific notation into 1.1 x10^-8
The rate of change of the given function at [-1,3] is 5
Further explanation:
Given function is:

And the interval is:
[-1,3]
In order to find the rate of chnage of function the given function's value is calculated at both points and divided by their difference
The formula is:

Here,
x_1 = -1
x_2 = 3
So,

Putting the values in the rate of change formula:

The rate of change of the given function at [-1,3] is 5
