-8/5x is the slope of the line.
Answer:
Y + 3= 3/4( x - 7)
Answer:
f(g(2)) = 22
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x + 1
g(x) = 2x² - 1
<u>Step 2: Find g(2)</u>
- Substitute: g(2) = 2(2)² - 1
- Evaluate: g(2) = 2(4) - 1
- Multiply: g(2) = 8 - 1
- Subtract: g(2) = 7
<u>Step 3: Find f(g(2))</u>
- Define: g(2) = 7
- Rewrite: f(7)
- Substitute: f(7) = 3(7) + 1
- Multiply: f(7) = 21 + 1
- Add: f(7) = 22
And we have our final answer!
Answer:
2y -x + 6 = 0
Step-by-step explanation:
Here a equation and a point is given to us and we are interested in finding a equation which is perpendicular to the given equation and passes through the given point .
The given equation is ,
Firstly convert this into slope intercept form , to find out the slope of the line.
Now on comparing it to slope intercept form which is y = mx + c , we have ,
And as we know that the product of slopes of two perpendicular lines is -1 . So the slope of the perpendicular line will be negative reciprocal of the slope of the given line. Therefore ,
Now we may use the point slope form of the line to find out the equation of the line using the given point . The point slope form is,
Now on substituting the respective values we have,
