Answer:

The slope is 0

Step-by-step explanation:

Given

(x_1,y_1) = (-8,0)

(x_2,y_2) = (4,0)

Required

The slope (m)

This is calculated as"

m=\frac{y_2-y_1}{x_2 - x_1}

m=\frac{0-0}{4 -(-8)}

m=0

<em>The slope is 0</em>

How do you find the base of this triangle? (Picture should be able to be seen)
vazorg [7]
The idea being, when you run a perpendicular line to the base, from the right-angle in a right-triangle, like in this case, what you end up with is, three similar triangles, a Large triangle containing the two smaller ones, a Medium triangle and a Small one, check the picture below.

since all three are similar, we can use the proportions on the corresponding sides, as you see in the picture, the base of the triangle then will just be x + y.

The exponential decay graph shows the expected depreciation for a new boat, selling for $3500, over 10 years a. Write an exponen
Alex Ar [27]
For the answer to the question above,  
<span>V(n) = a * b^n, where V(n) shows the value of boat after n years. 
V(0) = 3500 
V(2) = 2000 

n = 0 
V(0) = a * b^0 = 3500 
a = 3500 

V(2) = a * b^2 
2000 = 3500 * b^2 
b = sqrt (2000/3500) 
b ≈ 0.76 

V(n) = 3500 * 0.76^n 

We can check it for n = 1 which is close to 2500 in the graph: 
V(1) = 3500 * (0.76)^1 
V(1) = 2660 

And in the graph we have V(3) ≈ 1500, 
V(n) = 3500 * (0.76)^3 ≈ 1536 

Now n = 9.5 
V(9.5) = 3500 * (0.76)^(9.5) 
V(9.5) ≈ 258</span>

If the coordinates of point E are (-4, y), what is the value of<br> у?
BlackZzzverrR [31]

Answer:

-8

Step-by-step explanation:

First we need to find the slope of CD.

We know C is (-10, -2)

and we know D is (10,6)

If we use the slope formula, we can see the slope is m=\frac{6-(-2)}{10-(-10)}

m = \frac{8}{20} \\m=\frac{2}{5}

We can see point F is at (6,-4)

We can find the equation of this line by using point slope form, and plugging in F as our point.

y-(-4)=\frac{2}{5}(x-6)\\y=\frac{2}{5}x-\frac{32}{5}

To find where E, we need to find the y value when x = -4

y=\frac{2}{5}(-4)-\frac{32}{5}\\y =-8
