Answer:
C
Step-by-step explanation:
Answer:
Choice B is correct
Step-by-step explanation:
The variable x represents the number of hours;
2, 4, 5, 7, 9
The least value is 2 while the maximum value is 9. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 10. Choice A is incorrect since the values 7 and 9 will not be accommodated in the graph.
The y variable represents the number of pages read;
50, 100, 125, 175, 225
The least value is 50 while the maximum value is 225. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 250. Both choices C and D are incorrect since none of the values will be accommodated in the graph.
Answer:
6.5
Step-by-step explanation:
I'm not sure if its right but:
(2 × x) - 8 = 5
2x = 13
x = 6.5

Step-by-step explanation:
<u>Second-Degree Equation</u>
The second-degree equation or quadratic equation has the general form

where a is non-zero.
There are many methods to solve the equation, one of the most-used is by using the solver formula:

The equation of the question has the values: a=1, b=2, c=4, thus the values of x are


Since the square root has a negative argument, both solutions for x are imaginary or complex. Simplifying the radical

The solutions are
