Answer:

x=-1/2

Step-by-step explanation:

Solving

2x-1+8=6

2x+7=6

2x=6-7

2x=-1

x=-1/2

Checking

put x=-1/2 in equation

LHS 2(-1/2)-1+8

=-1-1+8

=8-2

RHS =6

Answer: $x=-1/2$

Simplify both sides of the equation

$2x+-1+8=6$

$(2x)+(-1+8)=6$ (Combine Like Terms)

$2x+7=6$

Subtract 7 from both sides

$2x+7-7=6-7\\2x=-1$

Divide both sides by 2

$2x/2=-1/2\\x=-1/2$

Scale : 1 cm = 2.5 ft

1 cm = 2.5 ft
0.5 cm = 2.5 x 0.5 = 1.25 ft

Circumference = πD = π(1.25) = 3.93 ft

Answer: 3.93 ft

Point m is the midpoint of kL. M(1,-1) and L(8,-7. What are the coordinates of point k?

Phoenix [80]

Answer: (-6, 5)

Step-by-step explanation:

Use the Midpoint Formula: $\dfrac{(x_k, y_k)+(x_L,y_L)}{2}=(x_m, y_m)$

Separate the x's and y's and solve them individually:

$\dfrac{x_k+x_L}{2}=x_m\qquad \qquad \qquad \qquad\dfrac{y_k+y_L}{2}=y_m\\\\\\\dfrac{x_k+8}{2}=1\qquad \qquad \qquad \qquad \qquad \dfrac{y_k-7}{2}=-1\\\\\\x_k+8=2\qquad \qquad \qquad \qquad \qquad y_k-7=-2\\\\\\x_k\quad =-6 \qquad \qquad \qquad \qquad \qquad y_k\qquad =5$

So, the k-coordinate is (-6, 5)
