Answer:

-8

Step-by-step explanation:

p(x) = - 2x - 3, x ≤ 0    You would use this equation for finding p(0), since 0 is equal to 0.

p(x) = - 2x - 3, x ≤ 0  ← You can ignore the x≤0 part.

p(0) = - 2(0) - 3              Input the value 0 as x.

p(0) = 0 - 3                    Simplify

p(0) = -3    

Next,

p(x) = -x² - 4, x > 0        You would use this equation for finding p(1), since 1 is greater than 0.    

p(x) = -x² - 4, x > 0    ←  You can ignore the x>0 part.  

p(1) = -(1)² - 4             Input the value 1 as x. 1² is equal to 1 times negative is -1.

p(1) = -1 - 4                 Simplify

p(1) = -5

Then,

p(x) = - 2x - 3, x ≤ 0    You would use this equation for finding p(-2), since -2 is less than 0.

p(x) = - 2x - 3, x ≤ 0  ← You can ignore the x ≤ 0 part.

p(-2) = - 2(-2) - 3          Input the value -2 as x. A negative times a negative is

p(-2) = 4 - 3                  a positive.

p(-2) = 1                        Simplify

Finally, you have to fine the value of \frac{p(0)+p(1)}{p(-2)}

\frac{p(0)+p(1)}{p(-2)}          

\frac{(-3) + (-5)}{(1)}            Input the values of p(0), p(1), and p(-2).

\frac{-8}{1}                      Simplify

-8

The answer is -8.

Answer:

Step-by-step explanation: What you want to do is find the grid point of each for example D is -4,-4 than you want to add those like B is 8,-6 so you would do -4+-8 and -4+-6 so you get 2,-10 for the distance of DB

Can someone plz help me on this plz I beg u
AfilCa [17]

Answer:

8

Step-by-step explanation:

So, lets go over a few things:

First off, all triangles have a total angle of 180 degrees.

Secondly, we know that the first two angles are 57 and 51.

Thirdly, we know that the missing angle is 9x

To solve this, we must add together the known angles, subtract them fro 180, and divide that by 9. This will give us the missing x value.

So, add together the two angles we know:

57+51

=

108

So we know 108 degrees of our triangle. We must find whats left of the 180.

To do this, subtract 108 from 180:

180-108

=

72

So our remaining angle is 72 degrres.

But recall that x isnt the misisng angle, 9x is.

So, to get x on its own, we must divide both the missing angle and 9x by 9:

72=9x

---  ---

9   9

=

8=1x

So now we know that x equals 8.

I hope this helps! :)

The cost C (in dollars) to participate in a ski club is given by the literal equation C=85x+60, where X=C/85-12/17 is the number
dybincka [34]

Given:

The cost C (in dollars) to participate in a ski club is given by,

\begin{gathered} C=85x+60 \\ (or) \\ x=\frac{C}{85}-\frac{12}{17} \end{gathered}

Where x is the number of ski trips we take.

To find:

The number of ski trips when a total cost of $315 and $485 is spent.

Explanation:

Substituting C = 315 in the given equation we get,

\begin{gathered} x=\frac{315}{85}-\frac{12}{17} \\ x=\frac{315-60}{85} \\ x=\frac{255}{85} \\ x=3\text{ ski trips} \end{gathered}

Substituting C = 485 in the given equation we get,

\begin{gathered} x=\frac{485}{85}-\frac{12}{17} \\ x=\frac{485-60}{85} \\ x=\frac{425}{85} \\ x=5\text{ ski trips} \end{gathered}

Thus,

If we spend a total cost of $315, we can take 3 ski trips.

If we spend a total cost of $485, we can take 5 ski trips.

Final answer:

• If we spend a total cost of $315, we can take 3 ski trips.

,

• If we spend a total cost of $485, we can take 5 ski trips.
