Answer:
You should also try solving it yourself to make sure I did not make any mistake.
Step-by-step explanation:
We already know the slope so, so far the equation should look like this.
Now we just need to insert the point into the equation. So point (7,9) 7 should replace the x and 9 will replace the y. It will look like this:
when you solve this equation you'll get b
So the equation is
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)
Using the elimination method, the value of x in the system of equations is calculated as: 8.
<h3>How to Solve a System of Equations by Elimination?</h3>To solve a system of equations given using the elimination method, do the following:
Multiply 2x - 5y = 1 by 2 and multiply -3x + 2y = -18 by 5 to get the following:
4x - 10y = 2 --> eqn. 1
-15x + 10y = -90 --> eqn. 2
Add
-11x = -88
Divide both sides by -11
x = 8
