Answer:
Nicole's average speed is
.
Step-by-step explanation:
Given,
Speed of Kristen = 
Time taken by Kristen to cover the distance = 
Solution,
We can find out the distance traveled by Kristen by multiplying speed with time.


The distance traveled by Kristen is equal to distance traveled by Nicole.
As the question said Kristen left 2 hours later and cover the distance in 3 hours.
That means Nicole take 5 hours to cover the distance.
So, For Nicole;
Distance = 150 km
Time = 5 hrs
Here we use the formula of speed.

Now substituting the values, we get;

Hence Nicole's average speed is
.
Answer:
It's the third option
Step-by-step explanation:
Function A is a parabola which opens upwards and has a minimum of 3.
The minimum of function A is 3 and the minimum of function B is -2. - 5 less than function A.
Answer:
B
Step-by-step explanation:
From the given information:
Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.
This implies that:
8x + 3(1) = 8x + 3
Also,
If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4;
i.e.
6(x) + 4(1) = 6x + 4
So;
the model that can determine when Sienna will have the same amount as Jacob is:
8x + 3 = 6x + 4
Answer: 9.3 because it’s a decimal .
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
It is not B because 7x^2 means multiplying the equation by seven. It isn't C because that would move the graph DOWN seven units. And it's not D because when it is in parenthesis like that, it means that it is a horizontal shift, not vertical.
