We have 
−x²<span> − 3x − 1 = −x − 4

let 
f(x)=</span>−x² − 3x − 1
g(x)= −x − 4
the solution for
f(x)=g(x) is the intersection both graphs

using a graph tool
see the attached figure

the solution are the points
(-3,-1)
and
(1,-5)

Answer:

(-3,-1) and (1,-5)

Step-by-step explanation:

Given : -x^2 -3x - 1 = -x -4

Let f(x)= -x^2-3x-1

Let g(x)=-x-4

Plot these graphs using graphical tool .

The intersection point of these two equations will be the solution .

Refer the attached graph.

Thus the intersection points are (-3,-1) and (1,-5)

So, the solution is (-3,-1) and (1,-5)

Thus the graph which gives the correct solution is attached below.

6 / (x + 6) = 10/15

10(x+6) = 90

10x + 60 = 90

10x = 30

Find slopes , ill mark brainlist
zepelin [54]

Answer:

\frac{3}{2} or 1\frac{1}{2}

Step-by-step explanation:

We are given a graph and asked to find the slope.

So we can see two coordinate points, one on (0, 3) and (2, 0).

When trying to find slope, we use the method rise over run, which basically means y over x as a fraction, in which you then divide.

So count how many times it'll take for x to get to y, base it off the picture below

Since we see our numbers to be divided are 3 over 2, do the division and you get 1 1/2.

Would this be negative though? No, since the graph is in an increase, not a decrease.

8.1 liters to meters
Wittaler [7]

The US equivalent of "liters to meters" would be something like
"quarts to yards", which is equally meaningless.

Liters and meters don't even measure the same thing.  Liters describe
volume, whereas meters describe length or distance.    They don't convert
to each other .

If volume units could be converted to length units, then you (or somebody
with a slightly better grasp of his math) would be able to figure out how many
inches of gas he put into his car last week, and the cost of a foot of milk.

An animal reserve has 40,000 elk. The population increases 11% a year. How long tell the population is equal to 80,000. If someo
sukhopar [10]

Answer:

7 years (This answer is to the nearest year)

Step-by-step explanation:

The way you could work this out is by trial and error. 11 % a year means that its population increases by 4400 annually. 40,000 X 1.11^1 gives you the amount it would be after one year (44000). I got the 1.11 because of the percentage (0.11) plus the amount you need to do percentage increase (1). Then all you do is keep on going up till you hit the number you need (80,000) after about 7 years the total would have hit 80,000 and would have actually went past it (83046)
