Answer:

c < -3

Step-by-step explanation:

-3 (c + 4) – 2 > -5

Multiply both sides by -1 (don't forget to flip the sign):

3 (c + 4) + 2 < 5

Distribute:

3c + 12 + 2 < 5

Combine like terms:

3c + 14 < 5

Subtract 14:

3c < -9

Divide by 3:

c < -3

The solution is c < -3.

On a coordinate plane, the endpoints of line segment JK are J(−10,12) and K(8,−12). Point L lies on line segment JK and divides

lakkis [162]

Answer:

The coordinates of point L are (4.4 , -7.2) ⇒ answer A

Step-by-step explanation:

Assume that point L is (x , y)

Point L divides the line segment JK into two line segments such that

the ratio of JK to KL is 5 : 1

The coordinates of point J are (-10 , 12)

The coordinates of point K are (8 , -12)

∵ $x=\frac{x_{1}m_{2}+x_{2}m_{1}}{m_{1}+m_{2}}$

∵ $y=\frac{y_{1}m_{2}+y_{2}m_{1}}{m_{1}+m_{2}}$

Let $(x_{1},y_{1})$ = (-10 , 12) and $(x_{2},y_{2})$ = (8 , -12)

and $m_{1}:m_{2}$ = JL : KL

∵ JK : KL = 5 : 1

∵ JK = JL + KL

∴ 5 = JL + 1

Subtract 1 from both sides

∴ JL = 4

∴ JL : LK = 4 : 1

∴ $m_{1}:m_{2}$ = 4 : 1

∵ $x=\frac{(-10)(1)+(8)(4)}{4+1}$

∴ $x=\frac{-10+32}{5}$

∴ $x=\frac{22}{5}=4.4$

∴ The x-coordinate of point L is 4.4

∵ $y=\frac{(12)(1)+(-12)(4)}{4+1}$

∴ $y=\frac{12+(-48)}{5}$

∴ $y=\frac{-36}{5}=-7.2$

∴ The y-coordinate of point L is -7.2

* The coordinates of point L are (4.4 , -7.2)

Which statement is true about point F?

Vadim26 [7]

Answer:

F is the midpoint of AA' because Line E G bisects AA'

Step-by-step explanation:

The picture of the question in the attached figure

we know that

When reflecting a figure, the image is congruent to the pre-image.

A reflection maps every point of the pre-image to an image across a fixed line. The fixed line is called the line of reflection.

The distance of each point of the pre-image from the line of reflection will be the same as the distance of each point of image from the line.

In this problem the line of reflection is E G

The distance A F is equal to the distance A'F

Point F is the midpoint segment A A'

Line segment E G bisects segment A A'

therefore

F is the midpoint of A A' because Line E G bisects A A'
