Answer:use a right triangle calc. On the web it does it for you and shows you how it got the answer.
Step-by-step explanation:
0, 3
- 10, 15
= -10, -12
therefore, the slope is 6/5, and the intercept (c) is as supplied, 3.
the equation, y=mx+c or y = a + bx, can be applied here where m or b = 6/5, and a or c = 3.
therefore the equation is y=6/5x+3.
To test this, you can put in y = 10(6/5)+3, which spits out y = 15. This way we know it *should* work.
3. 28 Quarters and 5 dimes.
C = 2pi r
C/2 Pi = r.
I believe this would be the solution.
This is a vertical parabola, because (x-1)².
Vertex of the parabola (1,1).
So line symmetry is x=1.
