Answer:
= n - 2
Step-by-step explanation:
Note the difference between consecutive terms is constant, that is
0 - (- 1) = 0 + 1 = 1
1 - 0 = 1
2 - 1 = 1
3 - 2 = 1
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 1 and d = 1, thus
= - 1 + n - 1 = n - 2

Step-by-step explanation:
Answer:
y = 3x + 8
Step-by-step explanation:
y = mx + b
m = slope
slope = change in y / change in x = (44 - 38) / (12 - 10) = 6/2 = 3
y = 3x + b
Now substitute any value from the table to find b. Let's use (10,38)
y = 3x + b
38 = 3(10) + b
38 = 30 + b
8 = b
so equation is y = 3x + 8
Answer:
1/3
Step-by-step explanation:
4/12 find greatest common factor with is 4
divide both by 4
4 divide by 4 equals 1
12 divided by 4 equals 3
so is 1 over 3
This is an example
Opposite angles formed by two intersecting lines are equal, so angle 1 is the same as angle 4. That means angle 1 = angle 5 as well.
When a line intersects two parallel lines, the corresponding angles are equal. That is, if r and s are parallel, then the angles formed when l intersects r are the same s the angles formed when l intersects s. Angle 1 = Angle 5, Angle 2 = Angle 6, and so forth. Since we know angle 1 = angle 5, so from that you can see that r and s are parallel
