Answers

Answer 1

Answer:

The mapping diagram that represents a relation that is not a function is the option A mapping diagram;

A. A mapping diagram with negative 6 pointing to negative 4 and 3; negative 1 pointing to 5; 7 pointing to 8

Step-by-step explanation:

The mapping diagrams of the given relations are presented using Microsoft Visio as seen in the attached drawings

From the given options, in option A, -5 is paired with both 4 and 3, therefore, giving an input or domain value, -5, that has two outputs in the range which are 4 and 3, therefore, the relationship between the left and right cells in option A is not a function because it is not defined as one input can have several outputs

Answer:
x=10
y=7.5
CE = 6
BD=4.5

Explanation:
Use similar triangles. Since you know one side length of the larger triangle, divide it by the hypotenuse of the smaller triangle to get the factor you are multiplying you side lengths by.

12.5 / 5
= 2.5

Multiply every other side length by 2.5

4 x 2.5 = 10
x = 10

3 x 2.5 = 7.5
y = 7.5

To get CE and BD subtract your values:

CE = 10 - 4
CE = 6

BD = 7.5 - 3
BD = 4.5

If Triangle ABC ≈ Triangle DBE, find the value of x.

Answers

Answer:

x = 49

Step-by-step explanation:

The sum of angles in a triangle add up to 180°.

∠CBA = ∠EBD (Vertically opposite angles are equal)

          = 52°

Since in the triangle DBE, you already know two of the angles, you can find ∠BDE which is equal to ∠CAB (x + 9)°.

∠BDE = 180° - 70° - 52°

          = 58°

∠BDE = ∠CAB

          = ∠(x + 9)°

          = 58°

x + 9 = 58

x = 58 - 9

x = 49

What point is the intersection of the graphs of the lines 2 x - y = 3
and x + y = 3?

Answers

Answer:

(2, 1 )

Step-by-step explanation:

Given the 2 equations

2x - y = 3 → (1)

x + y = 3 → (2)

Rearrange (2) expressing y in terms of x by subtracting x from both sides

y = 3 - x → (3)

Substitute y = 3 - x into (1)

2x - (3 - x) = 3

2x - 3 + x = 3

3x - 3 = 3 ( add 3 to both sides )

3x = 6 ( divide both sides by 3 )

x = 2

substitute x = 2 into (3) for corresponding value of y

y = 3 - 2 = 1

Solution is (2, 1 )

Solve: 7 -2x= 2(x - 4) - 1

Answer:

No

Step-by-step explanation:

We use the Pythagorean theorem.

a^2 + b^2 = c^2

7^2 + 12^2 = 49 + 144 = 193

13^2 = 169

Since 193 is not equal to 169, the triangle is not a right triangle.

A city planner is mapping out some new features for a triangular park. She sketches the park on grid paper. The coordinates of the vertices of the park are (1, 1), (1, 4), and (−3, 4).   The city planner wants to put a flower bed at the centroid of the park. What are the coordinates of the flower bed? (__,__)​

Answers

Answer:

The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)

Step-by-step explanation:

To find the centroid of a triangle, use this rule centroid = ([tex]\frac{x1+x2+x3}{3},\frac{y1+y2+y3}{3}[/tex]), where (x1, y1), (x2, y2), (x3, y3) are the vertices of the triangle

∵ The vertices of the triangle are (1, 1), (1, 4), (-3, 4)

∴ x1 = 1 and y1 = 1

∴ x2 = 1 and y2 = 4

∴ x3 = -3 and y3 = 4

→ Substitute them in the rule above

∵ Centroid = ([tex]\frac{1+1+-3}{3},\frac{1+4+4}{3}[/tex])

∴ Centroid = ([tex]\frac{-1}{3},\frac{9}{3}[/tex])

∴ Centroid = ([tex]-\frac{1}{3}[/tex] , 3)

The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)
