Answer:

The Answer to this problem is J=5 And K= -2

Step-by-step explanation:

All you have to do is go one by one until you think that you have the right answer use the Substitution Method to check your answers.

The way to get the answer is as simple as 123

{J+K=3  So then you would use 5 for the J and -2 for the k

The After math will look like this {5 + -2=3

The next answer will look like this {5 - -2=7

The reason for the second answer is because you cant subtract a negative so it will add 2 instead of subtracting 2 Good Luck Everybody!!!!!!!!!! : )

John's car is stopped at a red light. When the light changes, the car accelerates to 45 miles per hour in 15 seconds. What is th
Ede4ka [16]
Initial velocity of John's car (V1) = 0 miles per hour
Final velocity of John's car (V2) = 45 miles per hour
Time taken for acceleration = 45 seconds
Then
Acceleration = (V2 - V1)/Time taken
                     = (45 - 0)/15 miles per hour per second
                     = 45/15 miles per hour per second
                     = 3 miles per hour per second.
So the approximate rate of change in the miles per hour that John's car accelerated is 3 miles per hour per second. The correct option among all the options given in the question is option "A".

Find the equation of the line.<br> Use exact numbers.
Citrus2011 [14]

Answer:

y = 4x + -9

Step-by-step explanation:

The y intercept which is -9, is the point in which the graph crosses the x-axis

In order to find the slope we need to identify two clear points on the graph.

- (0, -9)

- ( 1, -5)

Now that we have our two points we need to find the distance between them.

As you can see on the attachment the distance between the two points is 4 units up and 1 unit to the right, therefore the slope is 4/1 = 4.

Final Answer: y = 4x + -9
