Answer:
Tour 1: c1(x) = 35 + 10x
Tour2: c2(x) = 35 + 15x
The functions have the same initial value.
Do you agree?

Actually Welcome to the Concept of the Straight lines.
Since there are more than one lines that can land plane safely, we take one of it,
When, X = 10 and Y = 7, so the equation we get as,
y-7 = m(x-10) + c
lets find slope, that is value of m,
y2-y1/x2-x1 = m
so, 9-7/ 7-10 = 2/-3
so, m= -2/3
so the final Equation is,
=> y-7 =(-2/3)(x-10) +c
In measurement problems such as these, we can use proportional relationships to determine the length or measure of triangular sides.This works because the two figures are similar. Our proportion is going to have a variable since we do not know the height of one of the flagpoles. It will be set up as such:

=

We cross multiply, then divide to solve this proportion.
32 x 5 = 160.
160/8 =
20.
This means the height of the flagpole is 20 feet high. To fit the height of the flag pole, the cord the school should buy for the flagpole should be 20 feet long.
The number of plates is an illustration of permutation and combination
The number of plates is 2592
<h3>How to determine the number of plates</h3>
The range is given as: AVVJ 144 To: BVNP 199 (exclusive)
From the range, we have the following highlights:
- The first letter can be either A or B (i.e. 2 letters)
- The second letter can be only V (i.e. 1 letter)
- The third letter can be from W to M (24 letters)
- There are 54 numbers between 144 and 199
The number of plates (n) is then calculated as:

Evaluate the product

Hence, the number of plates (n) is 2592

Step-by-step explanation:
step 1. what is the question? solve for x? okay.
step 2. 28/54 = (2x+ 8)/(5x - 4)
step 3. 28(5x - 4) = 54(2x + 8) (cross multiplication)
step 4. 14(5x - 4) = 27(2x + 8) (divide both sides by 2)
step 5. 70x - 56 = 54x + 216 (distributive property)
step 6. 16x = 272 (group x's and add 56 to both sides)
step 7. x = 17 (divide both sides by 16).
