-12p^2 - 12pq + 2p -3q^2 + q
Answer:
Part A: <u>Which point represents the origin? </u>
- The origin is the point with both zero coordinates: (0, 0)
Part B: <u>Starting from the origin, explain how to plot the following three points accurately (1,-1) (-1.1.25) (-2,3).</u>
Reference point is the origin for below.
- (1,-1) - go <u>right </u>by 1 unit and <u>down </u>by 1 unit, plot the point
- (-1.1.25)- go <u>left </u>by 1 unit and <u>up </u>by 1.25 or 1 and 1/4 units, plot the point
- (-2,3) - go <u>left </u>by 2 units and <u>up</u> by 3 units and plot the point
Answer:
y=x
Step-by-step explanation:
y=12
Let, the number of Lilies in each vase = x
Then, expression would be: 10(15+x)
150+10x
So, final answer is 150+10x
Where, x = number of lilies.
Hope this helps!
Answer:
<h2>
aₙ = -3n + 8</h2>
Step-by-step explanation:
The nth term of an arithmetic sequence: aₙ = a₁ + d(n - 1)
{d = common difference}
a₁ = 5
a₄ = 5 + d(4 - 1)
-4 = 5 + 3d
-4 - 5 = 3d
3d = -9
d = -3
Therefore;
aₙ = 5 + (-3)(n - 1)
aₙ = -3n + 8
Check: a₁₀ = 5 + (-3)(10 - 1) = 5 - 27 = - 22
