Answer:
X=-1
Step-by-step explanation:
(X-5)1/2+5=2
(X-5)1/2=2-5
(X-5)1/2=-3
(X-5)=-3 *2
X-5=-6
X=-1
Y = -10x + 1...slope here is -10. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal of a number, flip the number and change the sign. So our perpendicular line will need a slope of 1/10.
y = mx + b
slope(m) = 1/10
(5,7)....x = 5 and y = 7
now sub and find b, the y int
7 = 1/10(5) + b
7 = 1/2 + b
7 - 1/2 = b
14/2 - 1/2 = b
13/2 = b
so ur perpendicular line going thru (5,7) is y = 1/10x + 13/2

Answer:
FG = 19
Step-by-step explanation:
The two sides of the triangle are equal since JG is a perpendicular bisector
FG = HG
5x-6 = 3x+4
Subtract 3x from each side
5x-3x -6 = 3x+4-3x
2x-6 =4
Add 6 to each side
2x-6+6 =4+6
2x = 10
Divide by 2
2x/2 = 10/2
x =5
We want to find FG
FG = 5x-6
FG = 5(5)-6
= 25-6
= 19
Answer: x=3.2 AC= 42.8
Step-by-step explanation:
As point B lies at segment AC AC=AB+BC
Otherwise we can write the equation
5x+9x-2=11x+7.6
14x-2=11x+7.6
14x-2+2=11x+7.6+2
14x=11x+9.6
14x-11x=11x-11x+9.6
3x=9.6
x=9.6:3
x=3.2
AC= 11*x+7.6= 11*3.2+7.6=35.2+7.6=42.8
