Answer:
Step-by-step explanation:
We need to solve the quadratic equation
6 = x^2 -10x
Rearranging we get,
x^2-10x-6=0
Using quadratic formula to solve the quadratic equation
a= 1, b =-10 and c=6
Putting values in the quadratic formula
So,
<em>Note:</em>
<em>Your first question is missing the y-intercept, so I am solving the 2nd question. You would still get your concept clear because the procedure to solve each of the questions is the same.</em>
Question 2
Answer:
The equation in the standard form is:
- 2/3x + y = -4
Please also check the attached graph.
Step-by-step explanation:
We know that the equation in the standard form is
Ax + By = C
where x and y are variables and A, B and C are constants
Given
- Slope m = -2/3
- y-intercept = -4
To determine
- Write the equation in the standard form
We know that the slope-intercept form of the line equation
where
- m is the slope
- b is the y-intercept
In our case:
- Slope m = -2/3
- y-intercept = -4
substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation
y = mx+b
y = -2/3x + (-4)
y = -2/3x - 4
Writing the equation in the standard form
2/3x + y = -4
Therefore, the equation in the standard form is:
- 2/3x + y = -4
