Is 12 I think so !! try it
The answer is y=1 and x=-3
A graph shows the solutions to be
.. x = -3
.. x = 1
Here's an analytic solution.
.. f(x) = g(x)
.. -2x = x^2 -3 . . . . . . substitute the given function definitions
.. 0 = x^2 +2x -3 . . . . add 2x
.. 0 = (x -1)(x +3) . . . . . factor
Use the zero-product rule to find values of x that are solutions. One or the other of the factors must be zero for the product to be zero.
.. x -1 = 0 . . . . first factor is zero
.. x = 1
.. x +3 = 0 . . . second factor is zero
.. x = -3
Answer:
(0,3) and (7,0) are solutions.
Step-by-step explanation:
In a pair of coordinates, they are always listed as (x,y). Since this is the case, you plug in each coordinate to their respective places.
For (0,3)
3(0) + 7(3) = 21
0 + 21 = 21
For (7,0)
3(7) + 7(0) = 21
21 + 0 = 21
To double check that (1,2) isn't a solution:
3(1) + 7(2) = 21
3 + 14 = 21
17 = 21 X
This doesn't work.
Marking as Brainliest is much appreciated.
Using the relation between position and velocity, it is found that:
- A: Her speed increased at a consistent rate.
- B: She stopped at an intersection.
- C: Her speed increased at a consistent rate.
<h3>Relation:</h3>
- The velocity is the derivative of the position, that is, it is the rate of change of the position.
For each part, we have that:
- In part A, her <u>distance is increasing</u>, which means that the velocity is also increasing. The graph is a line, hence the derivative is a constant, which means that the increase was constant.
- In part B, she remains at the <u>same position</u>, hence, she stopped at an intersection.
- Part C is <u>similar to part A</u>, distance increasing, hence velocity increasing at a constant rate.
