Answer:
Solutions are (6,3) and (-2,3).
Step-by-step explanation:
From the first equation given we can write:
substituting for 
in the second equation given we get
∴ y=3
Putting y=3 in the first equation we get
x-2 = ±4
Hence x=6 or x=-2.
Answer:
X = 149
Step-by-step explanation:
A full circle is 360 degrees
Add 160+51=211
360-211=149
Answer:
y=0.5x+40
Step-by-step explanation:
Copy the equation.
x-2y=8
Subtract x from both sides.
-2y=-x-8
Divide both sides by -2.
y=0.5x+4
Now we know the slope is 0.5.
Any line with a slope of 0.5 will be perpendiculr to the original line.
One that you can use is y=0.5x+40.
The height of the surface increases, then decreases, from the center out to the sides of the road.
<h3>What is quadratic equation?</h3>
The polynomial having a degree of 2 is defined as the quadratic equation it means that the variable will have a maximum power of 2.
Let
y------> the height of the surface
x------> the road
we know that
The quadratic regression graphed represent a vertical parabola open downward
The function increase in the interval --------> (-5,0)
The function decrease in the interval --------> (0,5)
therefore
The height of the surface increases, then decreases, from the center out to the sides of the road.
