Answer:

B. x = 2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

check by substituting each given value of x into the function

x = 0 ⇒ y = × 0² = 0

hence (0, 0) is correct

x = 2 ⇒ y = × 4 = 3

hence (2, 4 ) is incorrect

x = 3 ⇒ y = × 9 = 6

hence (3, 6 ) is correct

x = 5 ⇒ y = × 25 = 18

hence (5, 18 ) is correct

What is the height of the trapezoid?

marta [7]

Answer:

11 units

Step-by-step explanation:

The height of a trapezoid is the distance between the parallel bases.

Here, one base lies on the horizontal line y=5, and the other lies on the horizontal line y = -6. The distance between them is ...

5 -(-6) = 5 +6 = 11

You can also find this distance by counting the grid squares between the two parallel lines.

The height of the trapezoid is 11 units.

_____

Additional comment

The base lengths are ...

AB = 2 -(-5) = 7

CD = 8 -(-7) = 15

The area is 1/2(b1 +b2)h = (1/2)(7 +15)(11) = 121 square units.

I'm am very confused with this question.

stich3 [128]

Answer:

103°

Step-by-step explanation:

This is a cyclic quadrilateral (all vertices on the same circle)

Opposite angles are supplementary:

∠A + ∠C = 180°
∠B + ∠D = 180°

Find x:

x + 5 + x - 7 = 180°
2x - 2 = 180°
2x = 182°
x = 91°

Find D:

∠D = x - 14°
∠D = 91° - 14° = 77°

Find B:

∠B = 180° - 77° = 103°
