Step-by-step explanation:
L.H.S =
sin15°+tan65°
sin(90°-75°)+tan(90°-25°)
cos75°+cot25°
or; cot25°+ cos75°. R.H.S
Let the number be x.
2*(x-4) < (x+5).
2x -8 < x +5
2x-x < 5 +8
x<13.
The number is less than 13.
That's it. Cheers.
Answer:
2
Step-by-step explanation:
The equation for this line is y=2x+1
The slope of the line is 2 because it moves 2 up on the y scale after it moves 1 on the x scale.
To find the axis of symmetry you must first find the vertex of the parabola. The formula for vertex is -b/2a. So the vertex has a "x" coordinate at 4/2 or 2. so the axis of symmetry is the vertical line x = 2
