Answer:
x=9,-1 and 
Explanation:
We are given the quadratic equation 
, which we then compare with the standard form of a quadratic. The general quadratic is identified as 
. From our given equation, it follows that a=1,b=-8,c=-9
. To calculate the discriminant, we insert these values into the formula 
. Now, to find the value of x
The formula is 
. The resulting equation will be obtained by rewriting the original equation through rearranging 9 to the right side and applying negative signs within brackets to convert the expression into the form of
.
Answer:
Therefore, the data is best represented by:
Step-by-step explanation:
We have a table indicating the estimated lines of code produced by computer programmers per hour when x individuals are engaged.
The question asks which model accurately reflects this data.
To determine this, we will substitute the values of x into each function to see which one accurately produces the corresponding y (f(x)) values provided in the table:
We are presented with four functions, which are:
A)
B)
C)
D)
We'll create a table displaying these values at various x levels.
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Thus, the function that suitably represents the data is:
Option C.
y=26.9x-1.3
The equation that demonstrates a proportional relationship, maintaining a constant of proportionality equal to 14, is: Here, and are proportional with a constant of proportionality of 14.
The midpoint of the line segment with endpoints (-6, -3) and (9, -7) is (1.5,-5).
Answer:
$10
Step-by-step explanation:
Each hardcover book costs $12, resulting in a total of $60 for five of them out of $100. The remaining four paperbacks at $10 each amount to a total of $40.
I hope this was helpful!!!:)
