Round the number in the tenths column (9), to the nearest tenth. (If it's 4 or less you round down, 5 or more you round up). The answer is 4.0.

Answer:
SAS

Explanation:
In triangle ABC:
a would be the side opposite to angle A
c would be the side opposite to angle C

Segment FG begins at point F(-2, 4) and ends at point G(-2, -3). The segment is translated 3 units left and 2 units up, then ref
Alexus [3.1K]

Answer:

F'G' = 7

Step-by-step explanation:

Given

F = (-2,4)

G = (-2,-3)

Required

Distance of F'G'

The transformation that give rise to F'G' from FG are:

  • Translation
  • Reflection

The above transformations are referred to as rigid transformation, and as such the side lengths remain unchanged.

i.e.

F'G' = FG

Calculating FG, we have:

FG = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}

Where:

F = (-2,4) --- (x_1,y_1)

G = (-2,-3) --- (x_2,y_2)

FG = \sqrt{(-2 - -2)^2 + (4 - -3)^2}

FG = \sqrt{(0)^2 + (7)^2}

FG = \sqrt{0 + 49}

FG = \sqrt{49}

Take positive square root

FG = 7

Recall that:

F'G' = FG

F'G' = 7

The table below shows some values of a linear function. What are the missing values
Black_prince [1.1K]

Answer:

C

Step-by-step explanation:

to get to 18 from 15, you add three.

You keep adding three to every number for the y values since it it a linear function. The x values went up by 1 and the y values went up by 3.
