The figure shows two triangles on the coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis an

d from positive 6 to negative 6 on the y-axis. A triangle ABC is shown with vertex A on ordered pair 4, 1, vertex B on ordered pair 3, 1, and vertex C on ordered pair 4, 4. Another triangle A prime B prime C prime is shown with vertex A prime on ordered pair negative 4, 4, vertex B prime on ordered pair negative 3, 4, and vertex C prime on ordered pair negative 3, 1. What set of transformations is performed on triangle ABC to form triangle A'B'C'? A translation 5 units down, followed by a 180-degree counterclockwise rotation about the origin A translation 5 units down, followed by a 270-degree counterclockwise rotation about the origin A 180-degree counterclockwise rotation about the origin, followed by a translation 5 units down A 270-degree counterclockwise rotation about the origin, followed by a translation 5 units down

Check the picture.

since the choices all have rotation about the origin, we must shift the original triangle in a suitable position. This is done by connecting any of the points of A'B'C' to the origin, and extend this line segment, as shown in the picture.

The most appropriate point is C', and we draw C" such that C'O=OC", and C', O and C" are collinear.

We see that the distance CC'' is 5.

So 

Answer is:

The data below are the ages and systolic blood pressures (measured in millimeters of mercury) of 9 randomly selected adults. Age
Ipatiy [6.2K]

Answer:

156

Step-by-step explanation:

Given the data:

Age (X) :

38

41

45

48

51

53

57

61

65

Pressure(Y) :

116

120

123

131

142

145

148

150

152

From the data, we could obtain a regression equation to mod the data Given using a linear regression calculator :

The regression equation obtained is :

y = 1.48769X + 60.46103

Using the model, the predicted blood pressure for a person aged 64 will be :

y = 1.48769(64) + 60.46103

y = 95.21216 + 60.46103

y = 155.67319

y = 156 (nearest whole number)

Solve for x <br> Need help asap
vlabodo [156]

Answer:

x=55

Step-by-step explanation:

Corresponding angles of two parallel lines are always equal. The angle on "top" of 2x+6 corresponds with the angle marked as x+9. Therefore, its measure must also be x+9.

Since these two angles form one side of a line which has 180 degrees, we have the following equation:

2x+6+x+9=180

Combine like terms:

3x+15=180

Subtract 15 from both sides:

3x=165

Divide both sides by 3:

x=\frac{165}{3}=\boxed{55}

Let f(x) = 5x + 4 and g(a) = a2 − 4a + 4 2 . Find the function value. g(−2)
natta225 [31]

Answer:  54

<u>Step-by-step explanation:</u>

replace "a" with "-2" in the g-equation

g(a) = a² - 4a + 42

g(-2) = (-2)² - 4(-2) + 42

        =  4       + 8   + 42

        =  54
