Answer:
Option A)
Step-by-step explanation:
We are given the following in the question:
Roots of quadratic equation are:
The sum of the roots and the product of the roots can be calculated as:
Standard form of quadratic equation:
Putting values, we get,
is the required quadratic equation.
Thus, the correct answer is
Option A)
Answer:
One equation would be y= -1.5x +11
Step-by-step explanation:
Here's a table to show the coordinates
x: y:
8 -1
-------------------
-4 17
the x coor. 8 goes down by 12 to get to the next x coor. -4.
8-12= -4
the y coor. -1 goes up by 18 to get to the next y coor. 17.
-1+18= 17
therefore 18/-12 is -1.5 which can be your k in y=kx+b.
Check your answer.
-1.5*8= -12 but when you add 11, you get the y coor. -1
Do the same with the other x coor.
-4*-1.5= 6 + 11 =17
11 can be your b in the slope-intercept form equation.
One equation may be y = -1.5x +11
Its 0.343 because it cannot be expressed as a fraction or whole number
This is a 90-60-30 triangle so the angle is 30 degrees.
