Add .25x to both sides to balance it out then divide by .4 the other side should be in fractio

0.5 = 0.4y - 0.25x

Since we're solving for (y), we have to get that variable alone

0.5 = 0.4y - 0.25x

+ 0.25x     + 0.25x

So add the 0.25x on both sides

0.25x + 0.5 = 0.4y

-----------------   -------

      0.4            0.4

Then divide everything by 0.4

0.625x + 1.25 = y

That's your answer (this is slope-intercept form, y = mx + b)

Guven the following absolute value function sketch the graph of yhe function and find the domain and range. F (x) = |x + 3| - 1
lana66690 [7]

Answer:

See below

Step-by-step explanation:

The graph is formed from f(x) = |x|.

f(x) = |x| is shaped like a V with the vertex at  the origin and the slope of each arm = 1.  Then f(x) = |x + 3| will have the same shape but will be moved 3 units to the left so the vertex  is at (-3,0). The - 1  ( to give f(x) = |x + 3| - 1) translates the whole graph 1 unit down so the vertex is at the point (-3, -1).

The domain is All Real x and the range = All real values of f(x)

equal or greater than -1.

A population of 50 timber wolves was introduced into a forest in 2009. The population is expected to grow by the function p(t)=5
Viktor [21]

Answer:

the population in 2015 is 8201.0695

Step-by-step explanation:

Given that

There is a population of the 50 timber wolves

And, the exponential function given is

p(t) = 50 × e^(0.85 × t)

Here t denotes the time period i.e.

= 2015 - 2009

= 6

So,

= 50 × e^(0.85 × 6)

= 8201.095

Hence, the population in 2015 is 8201.0695
