Answer:
4x^2 + 9x + 4 = 0
Using the quadratic formula:
x = [-9 +- sqrt(81 - (-64)] / 2 * 4
x = [-9 +- sqrt (145)] / 8
So, the solution is your second answer:
negative 9 plus or minus the square root of 145 divided by 8.
I'll pick B Hope this helps
To make this table, pick any value you want for x, then substitute it an solve for y.
For example, if you choose x=1, then
y=-2/3(1)-1
y=-2/3-3/3
y=-5/3
To do a three part table quickly, I like to use -1, 0, and 1 for the value of x, since -1 and 1 will not change the values, only the sign for -1, and 0 eliminates the m section of the equation.
I hope this helps !!!!
Pretty sure purple would be the first and green would be the last
Answer:
<em>x = 2.93</em>
Step-by-step explanation:
The sum of angles of the triangle is 180degrees, hence;
9x - 72 + 73x + 11 = 180
82x - 61 = 180
82x = 180 + 61
82x = 241
Divide both sides by 82
82x/82 = 241/82
<em>x = 2.93</em>
<em>Note that the functions might not be accurate but the same methos should be employed for any function given</em>
