Answer:
F 8.4
Step-by-step explanation:
4 [ 4.5 - 2(1.2)]
First, multipy 2 and 1.2
2 x 1.2 = 2.4
Then subtract 2.4 from 4.5
4.5 - 2.4 = 2.1
Last, multiply 2.1 from 4
4 x 2.1 = 8.4
Answer:

Answer:
vertex = (- 3, - 8 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = - 4(x + 3)² - 8 ← is in vertex form
with (h, k) = (- 3, - 8 ) ← vertex
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!
