your brand new 20,000 car will depreciate to 2,000 at a constant rate in ten years. Write a linear model relating the value "v"
koban [17]
Define
v =  value after t years.

Therefore the linear model is
v = mt + c
where
 m = depreciation rate
t = years since purchase
c =  constant

When t=0, v = 20,000, therefore
20000 = m(0) + c
c = 20000

When t=10, v = 2000, therefore
2000 = 10m + 20000
-18000 = 10m
m = -1800

Answer:
The linear model is
v = -1800t + 20000

Melissa is planning a rectangular vegetable garden with a square patch for tomatoes. She wants the length of
e-lub [12.9K]

The length of the vegetable garden as a function of its length will be given as:

  • y = 3x + 2

The expression of the garden width in terms of the width of the tomato patch is given as:

  • y = x + 5

  • Let the length of the garden be y

  • Let the length of the tomato patch be x

If Melissa wants the length of  the garden to exceed three times the length of the tomato patch by 2 feet, the length of the vegetable garden as a function of its length will be given as:

  • y = 3x + 2

If she also wants the garden's width  to <u>exceed the width of the tomato patch by 5 feet,  t</u>he expression of the garden width in terms of the width of the tomato patch is given as:

  • y = x + 5

Find x and TU<br> Show all the work
Licemer1 [7]

Answer:

x = 10

TU = 24

Step-by-step explanation:

To find the value of x, we use the trapezoid mid-segment theorem

The sum of the lengths of the two parallel sides is equal to twice the length of the mid segment

Mathematically, we have this as;

2(2x+ 4) = 2x-4 + 3x + 2

4x + 8 = 5x - 2

5x -4x = 8 + 2

x = 10

TU = 2x + 4 ; = 2(10) + 4 = 20 + 4 = 24

((3^3 - 7) • 5)/10 + ((1+3+6+9)-10)
jasenka [17]

Answer:

19

Step-by-step explanation:

(33−7)(5)/10+1+3+6+9−10

= (27−7)(5)/10+1+3+6+9−10

= (20)(5)/10+1+3+6+9−10

= 100/10+1+3+6+9−10

=10+1+3+6+9−10

=10+4+6+9−10

=10+10+9−10

=10+19−10

=10+9

=19
