8. The y-intercept is -10. You can find this by just seeing where the line would hit the y-axis. This is basically the starting point so the Scuba Diver's decent started at -10m.
9. You have the y-intercept so put that in slope-intercept form. y=mx+b
y=mx - 10
Now find the slope by picking two points and using the slope formula. I'll use
(30,-6) and (50,-4), and then plug in the values. 30 = x1, -6 = x2, 50 = x2, -4 = -4. Simplify.
m= y2-y1 -4 - (-6) 2 1
-------- = ----------- = --- / 2 = ---
x2-x1 50 - 30 20 10
Linearly, because the table shows that temperature increased by the same amount each month (2.2). If it were exponentially, the temperature would increase by the same percentage each month.
Answer:
2 and 4.
Step-by-step explanation:
- 2 is not a square because a trapezoid does have 4 sides, but the sides are not parallel, or congruent. ↓
- 4 is not a square because similar to the trapezoid, it does have 4 sides, but is not parallel nor congruent. ↓
- Although some people consider a rectangle a square, it is a square and also is not because it has 2 pairs of parallel sides, instead of all 4 sides being parallel.
Hope it helps!
Answer:
Associative property of addition
Step-by-step explanation:
its the same order only the () move
I think the correct answer from the choices listed above is option C. <span>The graph of a system of equations with the same slope and the same y-intercepts will never have no solutions. Rather, it has an infinite number of solutions since all points of the lines intersects.</span>
