Answer:
-x^5 - 7x^4 + x^2 + (1/8)x - 9
Step-by-step explanation:
Rewrite the given -9+1/8x-7x^4+x^2-x^5 in descending order of the variable x:
-9+1/8x
-x^5 - 7x^4 + x^2 + (1/8)x - 9
Answer
W= 43

Answer:
y=-x^2-4x-8 or y=-(x+2)^2-4
Step-by-step explanation:
First use the vertex form(because you have vertex point)
y=a(x+2)^2-4
Then, plug in the point(-1,-5) to find the equation
-5=a(-1+2)^2-4
-5=a-4
a=-1
y=-(x+2)^2-4 = -x^2-4x-4-4 = -x^2-4x-8
Answer:
y = 2x + 3
Step-by-step explanation:
We can make 2 coordinate points and find equation of the line using the line formula.
We can say that at starting (0 months), there were 3 employees.
After 8 months, there were 19 employees.
<em>Let months be x points and number of employees be y points.</em>
Thus, 2 points would be:
(0,3) & (8,19)
Now, the equation of the line is given as:
Where m is the slope and b is the y-intercept
Let's find slope first with the formula:
Where
x_1 = 0
x_2 = 8
y_1 = 3
y_2 = 19
Thus, we have:
Slope =
Now we have:
y = 2x + b
To find b, we put (0,3) into the equation:
y = 2x + b
3 = 2(0) + b
3 = 0 + b
b = 3
So the equation of the line is:
y = 2x + 3
