This is the concept of geometry, the function given by f(x)=cos^x
can be written as cos y=x
The domain if the function is [-1,1] and the range is given by [0,π] where π=180°
Answer:
y = x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = , then
y = x +c ← is the partial equation
To find c substitute (- 4, - 3) into the partial equation
- 3 = - 3 + c ⇒ c = - 3 + 3 = 0
y = x ← equation of line
Answer:
(4,19)
Step-by-step explanation:
Cuz if u substitute these values in for the x and y in the equation, the equation would be true:
1.) 19 <em>= </em>7(4) - 9
2.) 9 <em>≠</em> 7(54) - 9
3.) 30 <em>≠</em> 7(-3) - 9
4.) 15 ≠ 7(2) - 9
As you can see, 1st equation is the only equation that's true.
Hope this helps!
