Answer:
The lines are parallel to each other.
To figure this out you need to use the formula: m = y2 - y1 / x2 - x1
m represents the slope of the line.
So for the first line:
m = 4 - 2 ÷ -5 - (-9)
m = 2 / 4
Simplify: m = 1 / 2
The slope of the first line is 1 / 2.
For the second line:
m = 6 - 4 ÷ 1 - (-3)
m = 2 / 4
Simplify: m = 1 / 2
So, you can see that the slopes of both lines are the same. When the slopes are the same, that means that the lines are parallel to each other. When the coordinates are the same, that means that the lines are the same. When the slopes are flipped to each other and have are the opposite sign (positive or negative), then the lines are perpendicular.
Answer:
3x-2y-1=0
or, 3x-2y=1
or, x=(1+2y)/3...(i)
4x+y=27... ...(ii)
solving (i) and (ii)
(4+8y)+3y=27x3
4+11y= 81
11y=77
y=7
now,
x=(1+2x7)/3
x=5
hence, the passing point is (5,7)
now, for the radius of circle
radius of circle= distance betn (5,7) and (2,3)
r= √(5-2)²+(7-3)²
r=5units
finally,
the eqn of circle
(x-h)²+(y-k)²=r² (where (h,k)=(2,3) )
(x-2)²+ (y-3)²=5²
x²-4x+4+y²-6y+9=25
x²+y²-4x-6y=12....this is the required answer.
X+12=20 is 8.
x-9=17 and 2x=16 both have the same solution.
The answer should be X+12=20.
This is a difference of 2 perfect squares where you can factor x^2-y^2=(x-y)(x+y) so
also if it is equal to zero and you factor, then each factor is assumed set to zero exg
xy=0 then assume x and/or y=0 so
4x^2-100
(2x)^2-(10)^2=(2x-10)(2x+10)=0
so the roots are (2x-10) and (2x+10)
(solution is 5 and -5)
I think she ate 4/8
Because if you multiply 3/4 x 2 you’ll get 6/8 and subtract 6/8 and 2/8 and you’ll get 4/8 I hope this helped!!!
