Most of the information's required for solving this problem is already given in the question. Let us write them down first and then concentrate on the problem in hand.

When y = 5, then x = 2.5
So
y = kx
5 =2.5k
k = 2
Now, when x = 10, then
y = kx
  = 2 * 10
  = 20
From the above deduction, we can conclude that the correct option among all the options that are given in the question is the last option.

(Question 63) I have the answer in my book, but I have no idea how they got it, so any explaination would be super helpful! Than
vitfil [10]

You have to know that the graph of the arctangent function is a flat S-shaped curve that goes through (0, 0) and has asymptotes at ±π/2. The factor of 2 that multiplies it here expands it vertically so the asymptotes are at ±π. The +3 added to the x causes it to be shifted to the left by 3 units.

Why is there always more than one parallelogram with the same area and base​
BaLLatris [955]

Answer:

If every line parallel to two lines intersects both regions in line segments of equal length, then the two regions have equal areas. In the case of your problem, every line parallel to the bases of the two parallelograms will intersect them in lines segments, each with a width of ℓ.

System OT<br> W + b =13<br> 6.5w + 2b = 57.5
mixer [17]

Answer:   w = 7,  x = 6

Step-by-step explanation:  Solve by substitution

W + b = 13

rewrite as   b = 13 - w  and substitute that value for b in the second equation

6.5w + 2b = 57.5  Then solve for w

6.5w + 2(13-w) = 57.5 . Distribute

6.5w + 26 - 2w = 57.5 .  Subtract 26 from both sides. Combine like terms and simplify

6.5w - 2w = 57.5 - 26

4.5w = 31.5  Divide both sides by 4.65

w = 7 . Substitute 7 for w in the first equation and solve for b

7 + b = 13 . Subtract 7 from both sides

b = 6

If you use that formula and sub in the coordinates

-4 - 5 / -1-2

-9/-3

= 3

The slope should be 3/1
