Answer:
Step-by-step explanation:
1. y = -2x + 7
2. Graph it (Mark (0, 7) or 7 on the y axis and go over one, down two, mark it and draw a line through both)
3. -2y = -x + 6
4. divide entire equation by 2 to isolate y
5. -y = -x + 3
6. multiply entire equation by -1 to make it positive
7. y=x+3
8. graph it (Mark (0,3) and go over one, down one, mark it and draw a line through both new points)
9. Where the lines intersect is your answer
8.25 inches once you multiply the 3/4 by 2 and add that and also add the 3/4 from the previous week you’ll get your answer
Use m=y2-y1/x2-x1 when you find the slope of two coordinates :)
Answer:
x = 34
Step-by-step explanation:
-8 = dropped 8 degrees
26 = 26 degrees at midnight
x = temperature at 6
x - 8 = 26
(add 8 to both sides) x = 34
Another way to say f(x) is y, so y=0 at -2 and 10. :)
