Answer:
(0, -3) is the y intercept
the slope is equal to 7
Step-by-step explanation:
Answer:
There is no solution, y-int of one line is positive
Step-by-step explanation:
There is no solution because there are no shared points between both lines, and the y intercept of the blue line is positive, because it is above the x-axis.
Answer:
the third one

Step-by-step explanation:
<u>Modeling With Functions
</u>
We have a table of values of speeds vs distance taken for a car to stop. We are required to find a model that uses the square root and fits the given data to predict other values of d as a function of v.
By the nature of the problem, we can know that for v=0, d must be 0 too. So our model won't include a vertical shift or independent term. Being v the speed of the car and x the distance it takes to stop, we use the following model

We must find A to make the function fit the data. Let's use the first point (v,x); (20,9)

Solving for A


Then we have

Evaluating for v=35
