y = - x + 3
the equation of a line in slope-intercept form is
y = mx +c ( where m is the slope and c the y-intercept )
rearrange x + 4y = 12 into this form
subtract x from both sides
4y = - x + 12 ( divide all terms by 4 )
y = - x + 3 ← in slope-intercept form
Hey there! I'm happy to help!
Tan means tangent. The tangent is the ratio of the opposite side of the angle to the adjacent side of the angle.
If we look across from angle C, we see that the opposite side is 5.
The adjacent side is the one next to the angle, and it can't be the hypotenuse (the diagonal one). Our adjacent side is 13.
So, the tangent of C is 5/13, and we can divide these, giving us about D. 0.38.
Have a wonderful day! :D
Answer:
The correct option is (C).
Step-by-step explanation:
We need to find the correct option that does not represent y as a function of x.
In options A, B, D and E, both x and y are involved. It means we can represent y as a fucntion of x.
But in option (c), it has only y as a variable i.e.
-4y=-8
y=(8/4)
y = 2
<em>So, this option does not represent y as a function of x. </em>
