Answer:

Step-by-step explanation:

There are so many order pairs that can solve this equation.

To solve this problem, we choose any value of x and find y;

Given expression;

3x - y = 8

if x = 0,

3(0) - y = 8

-y = 8

y = -8;

(0,-8) is a solution

ii.

if x = 1,

3(1) - y = 8

- y = 8 - 3

y = -5

(1, -5) is a solution

Answer:

7π cm² ≈ 22.0 cm²

Step-by-step explanation:

The shaded area is the difference between the area of Circle B and the areas of Circle C and Circle O. That is, those white areas are subtracted from the area of Circle B to get the shaded area.

The formula for the area of a circle is

A = πr²

Using this, we find ...

Circle B area = π(3 cm)² = 9π cm²

Circle C area = Circle O area = π(1 cm)² = π cm²

Then the shaded area is ...

Shaded Area = Circle B area - Circle C area - Circle O area

= (9π cm²) - (π cm²) - (π cm²)

= 7π cm² ≈ 22 cm²

Answer:

Step-by-step explanation:

by looking at the given image...

the shape ABCD is a parallelogram.

Required:

is to prove ∡A and ∡B are supplementary

and ∡C and ∡D are supplementary.

so, m∠A + m∠B = 180°

and m∠C + m∠D = 180°

the Statement

1. ABCD is a parallelogram

the reason is..

It is Given!

the Statement

2.m∠A=m∠C and m∠B=m∠D

the reason is..

Definition of parallelogram.

the Statement

3.m∠A+m∠B+m∠C+m∠D=360°

the reason is..

Definition of quadrilateral

the Statement

4. m∠A+m∠B+m∠A+m∠B=360°

the reason is..

By substitution

⇒ 2( m∠A + m∠B ) = 360°

⇒ m∠A + m∠B = 180°

it is also similar m∠C + m∠D = 180°

the Statement

5.∠A and ∠C are supplementary

the reason is..

by the definition of Supplementary ∠ B and ∠D are supplementary

Hope it helps!
