Sorry i have learnt it but i can remember how to do it
C. Vertex (x,y). The vertex is right in the middle of the quadratic graph.
Answer:
3/5
Step-by-step explanation:
Cos(B) = adjacent/hypotenuse
Cos(B) = 48/80 = 6/10
Cos(B) = 3/5 or 0.6
A.R = 34x
B. 4x+180= 34x
180=30x
x=6
Answer is 6.
The equation is x=-6
Step-by-step explanation:
In standard form the equation is y=4
And this is a horizontal line so the perpendicular line will be a vertical line of the form x=a
so that is why the equation is x=-6
