Answer:
The line AB, with A(Ax, Ay), B(Bx, By) and midpoint M(Mx, My) satisfying:
Ax + Bx = 2Mx
Ay + By = 2My
=>
2 + Bx = 2*1
5 + By = 2*2
=> Bx = 0
=> By = -1
=> B(0, -1)
Hope this helps!

Answer:
(a) The constant of proportionality is 0.25
(b) 1 apple = $0.25
(c) $3 = 12 apples
Step-by-step explanation:
Given

Solving (a): The constant of proportionality;
For an equation:

Where
k = constant of proportionality
By comparing:
to 

Hence, the constant of proportionality is 0.25
Solving (b): What information does
gives.
It represents the unit rate.
<em>So, it means that 1 apple costs $0.25</em>
<em></em>
Solving (c): Number of apples for $3.
This means that 
Substitute 3 for c in 

Make n the subject


Answer:
I think the answer is 5.75 miles.
Step-by-step explanation:
If the drone flies 2,530 ft in 5 seconds, that means that in one minute it flies 30,360 ft. And 30,360 divided by 5,280 is 5.75.

Answer:
p is proportional to q, r, t, and inversely proportional to s
Step-by-step explanation:
Assuming k is a "constant of proportionality," the value of p is directly proportional to each of the numerator variables: q, r, t. P is inversely proportional to the denominator variable, s.
