Slope = (y2 - y1)/(x2 - x1)
Let's plug in our values: (10 - 9)/(5 - - 6)
This gives us 1/11 as our slope.
Answer:
The answer is ""
Step-by-step explanation:
For point 1:
For point 2:
Adding equation and multiply by 2 in the equation so we get
The quadratic equation may be expressed in a form, ax² + bx + c =0. From the given equation, a = 2, b = 1, and c = -3. Substituting these value to the equation of the discriminant (D).
D = b² - 4ac
D = 1² - (4)(2)(-3) = 25
Thus, the discriminant of the equation of 25.
Answer:
2x - 19
Step-by-step explanation:
"Twice a number x" means the (missing) number is called x. Write "2x" which means multiply "x" by 2.
"Minus 19" is -19.
Together, the expression is 2x - 19.
