Answer:
the answer is C. No, it fails the vertical line test.
After a 25% discount...means that u paid 75%
so 75% of the original cost is 18.50...
0.75x = 18.50.....with x being the original cost
x = 18.50 / 0.75
x = 24.666 rounds to 24.67 <==
Answer:
3
Step-by-step explanation:
Y2-y1/x2-x1 to find the gradient. So -1-8/4–8= -9/12. Then substitute into any of the coordinates. I chose -1=4(-9/12)+c. Rearrange to get c alone. Answer altogether is : y=-9/12x+2
This has exactly two solutions.
You can find the number of a solutions that a problem has by its highest power of x. Since x is raised to the 2nd power in here, it has two solutions. In some cases, these solutions will be irrational, double roots, or non-real, but there will still be two of them regardless.
