Expand: -2s+14>4s+8, 6>6s, 1>s so s must be less than 1. This can be written [−∞,1).
The answer is 4.77 euro.
First I found out what the cost of one pen was.
I did: 6.36/12 pens
The answer was: 0.53
Then I did 0.53 times 9
And I got the answer.
Can you please tell me how to add a picture to a question though?
The correct answer should be B: y = -3x + 2.
Since the line crosses the y axis at 2, your y-intercept should be 2. Using rise over run you can compare the equations to the graph. If you convert 3x to a fraction, it would be 3/1x. Since the line is going down 3 and the rise of the y = -3x + 2 is -3, that part is correct. The line also moves over 1 unit, so the run is 1, therefore the correct slope would be -3 or -3/1. Now if you combine what you have it should be y = -3x - 2, which is the same equation as B.
Answer:
I just graphed it in desmos for you UvU
The second answer is false. The vertex is not (-3, 11). The vertex is (3, 11). I can see that the parabola has a point of (1, 19), and the parabola opens upward, as well as has an axis of symmetry; x = 3.
Hope that helps
