Ratio 1:5....added = 6
complimentary angles, when added, = 90 degrees
1/6(90) = 90/6 = 15
5/6(90) = 450/6 = 75
so ur 2 angles are : 15 and 75
Distance = sqrt(5- -6)^2 + (3- -6)^2)
= sqrt (121 + 81)
= sqrt 202
= 14.21 to nearest hundredth
|x| < 7
means x < 7 and x > -7
answer is -7 < x < 7
Answer:
4 i think im not sure
Step-by-step explanation:
Subtract yy from both sides of the equation.
4x=8−y4x=8-y
y=kx+2y=kx+2
Divide each term by 44 and simplify.

x=2−y4x=2-y4
y=kx+2
The easiest way is to try the point (-4,1), that is, x=-4, y=1,
to see which equation works.
b works.
The usual way to do it is to find the equation of the circle
standard form of a circle is (x-h)²+(y-k)²=r², (h,k) are the coordinates of the center, r is the radius.
in this case, the center is (-2,1), so (x+2)²+(y-1)²=r²
the given point (-4,1) is for you to find r: (-4+2)²+(1-1)²=r², r=2
so the equation is (x+2)²+(y-1)²=2²
expand it: x²+4x+4+y²-2y+1=4
x²+y²+4x-2y+1=0, which is answer b.
