Step-by-step explanation:
soln
given
y=2x+3 -----(i)
y=-x-9 ------(ii)
now, putting value of equation (i) in (ii)
y= -x-9
or, 2x+3 = -x-9
or, 2x+x = 9-3
or, 3x = 6
or, x = 6/3
or, x = 2
again,
y = 2x+3
or, y = 2×2+3
or, y = 7
therefore, value of X and Y are 2 and 7 respectively.
X = base / tan(angle)
x = 8.9 / tan(55)
x = 6.23
x= 6.2
Answer is A
Answer:
The equation of the line is y = 2x - 2
Step-by-step explanation:
In order to find this, we first need to find the slope. For that we use slope intercept form.
m(slope) = (y2 - y1)/(x2 - x1)
m = (6 - 4)/(4 -3)
m = 2/1
m =2
Now that we have this, we can use the slope and either point in slope-intercept form to get the equation.
y - y1 = m(x - x1)
y - 4 = 2(x - 3)
y - 4 = 2x - 6
y = 2x - 2
Perimeter of circle = 2*r*pi
r = 3
2*3m*pi = 6pi
6pi = 18.850m
There perimeter of the circle is 18.850 meters. You travelled 1/3 of the way, which means it's 1/3*18.850 = 6.2833 m
