Answer:
x = 6
Step-by-step explanation:
Complementary angles always equal 90 degrees so something multiplied by 12 will have to equal something that will add up with 18 to get 90 so
12 × 6 = 72 and 72 + 18 = 90 Hope this helps you!
Basically the graph of this, would simply be a horizontal line, where although the X values change, the y coordinate is the same for all of them.
For instance certain ordered points can be - (-1,4), (0,4), (1,4), (2,4) ...
Answer:
2
Step-by-step explanation:
<u>Given AP where:</u>
<u>To find</u>
<u>Since</u>
- a₄ = a₁ + 3d
- a₂ = a₁ + d
- a₆ = a₁ + 5d
<u>Initial equations will change as:</u>
- a₁ + 3d = 2(a₁ + d) - 1 ⇒ a₁ + 3d = 2a₁ + 2d - 1 ⇒ a₁ = d + 1
- a₁ + 5d = 7 ⇒ a₁ = 7 - 5d
<u>Comparing the above:</u>
- d + 1 = 7 - 5d
- 6d = 6
- d = 1
<u>Then:</u>
- a₁ = d + 1 = 1 + 1 = 2
- a₁ = 2
The first term is 2
8, 8, 8, 8, 8, 9, 9, 9, 9 would work as a sequence.
Median: 8
Mean: 8.4444....
