Answer:

5 months

Step-by-step explanation:

Set up an inequality, using x to represent months.

(The 35 and 40 represent the cost per month, and you add the 100 and 75 just once because it's a one-time fee and not monthly)

35x + 100 < 40x + 75

Now solve for x.

5x > 25

x > 5

This means that the membership will be less expensive after 5 months.

Consider the linear function f(x)=4x -5.<br> Find f(3), f(0), f(-2).

nika2105 [10]

Answer: f(3)= 7, f(0)= -5, f(-2)= -13

Step-by-step explanation:

Substitute and plug in.

For f(3), we plug in 3 for x in the equation.

So, 4(3)-5, which is just 12-5, which is 7

We do the same for f(0),

4(0)-5, which is 0-5, which is -5

Once again for f(-2),

4(-2)-5, which is -8-5, which is -13

Hope this helps!

A forest covers 52000 acres. A survey finds that 0.4% of the forest is old-growth trees. How many acres of old-growth trees a

maxonik [38]

Given:

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

To find:

The area of old growth trees.

Solution:

We have,

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

Area of old growth trees is

$Area=0.4\% \text{ of total forest area}$

$Area=\dfrac{0.4}{100}\times 52000$

$Area=0.4\times 520$

$Area=208$

Therefore, the area of old growth trees is 208 acres.
