<h3>Answer: -2</h3>

Explanation:

Check out the diagram below. I started at -8 on the x axis number line. This number line is horizontal. Then I went straight down to arrive at the function curve. Afterward, I went directly to the right to get to the y axis. The final destination is y = -2

Therefore, f(-8) = -2

If 4g^2 -1= 16h^2 -1, what is the value of g in terms of h?<br> Plz explain

ale4655 [162]

Answer:

g = ±2h

Step-by-step explanation:

4g^2 -1= 16h^2 -1

Add 1 to each side

4g^2 -1+1= 16h^2 -1+1

4g^2 = 16h^2

Divide each side by 4

4/4g^2 = 16/4h^2

g^2 = 4 h^2

Take the square root of each side

sqrt(g^2) = ±sqrt(4h^2)

g = ±sqrt(4h^2)

g = ±2h

You can take LCM and then can add to see what's the sum.

The sum result of given expressions is given by: $\dfrac{5}{y+5}$

<h2>Given that:</h2>

To find sum of $\dfrac{3y}{y^2 + 7y + 10}$ and $\dfrac{2}{y+2}$

<h2>Finding LCM and summing:</h2>

You can take LCM and then can add to see whats the sum.

$\begin{aligned}\dfrac{3y}{y^2 + 7y + 10} + \dfrac{2}{y+2} &= \dfrac{3y}{(y+2)(y+5)} + \dfrac{2}{y+2}\\&= \dfrac{3y + 2(y+5)}{(y+2)(y+5)}\\&= \dfrac{5y+10}{(y+2)(y+5)}\\&= \dfrac{5(y+2)}{(y+2)(y+5)}\\&= \dfrac{5}{y+5}\\\end{aligned}$

Thus, the sum of given expressions is given by:

$\dfrac{5}{y+5}$

Answer: 10 verticesTo make a full circle(360 °), the number of 40° lines you need will be: 360/40=9 lines. So, the base of the pyramid would be made of 9 lines.Pyramid has a base and sides. The sides number is equal to the number of lines of the base. Then, the number of faces/vertices would be: 1 + 9= 10
If the question saying literally 40 edges(not degrees), then the pyramid base would be 40 lines. In this case, the number of vertices would be: 1+40=41
