Answer:

(2, 18) and (-3, -7)

Step-by-step explanation:

y = 5x + 8 Substitute the value for y into the second equation

-10x + 2y = 16

-10x + 2(5x + 8) = 16

-10x + 10x +16 = 16

16 = 16 True

These two equation are the same line. So pick one of the equation to check which ordered pairs are true solutions.

Using y = 5x + 8

(0, -6) -5 = 5(0) + 8 ; -6 = 8 No

(-1, 9) 9 = 5(-1) + 8; 9 = -5 + 8 ; 9 = 3 No

(2, 18) 18 = 5(2) + 8; 18 = 10 + 8 = 18; 18 = 18 Yes

( -3, -7) -7 = 5(-3) + 8; -7 = -15 + 8; -7 = -7 Yes

What is the area of the shaded sector

Whitepunk [10]

Answer:

Area = 634.21 square metre

Step-by-step explanation:

Area of shaded region = Area of the circle - Area of the sector

$Area \ of \ the \ circle = \pi r^2 = 225 \pi\\\\Area \ of \ the \ sector = \pi r^2 \frac{ \theta}{360} = \pi \times 225 \times \frac{37}{360}$

$Area \ of \ shaded \ region = 225 \pi - (225 \pi \times \frac{37}{360})$

$= 225 \pi (1 - \frac{37}{360})\\\\= 225 \pi \times 0.89722\\\\=634.21 m^2$

If angle A is (2x+8) degrees and Angle B is (2x+8) and A and B are supplementary angles....what is measurement of angle B?

atroni [7]

<h3>Supplementary Angles:</h3>

Angles which adds up to 180°.

<h3>Given:</h3>

A = 2x + 8

B = 2x + 8

The measurement of B.

<h3>Solution:</h3>

A + B = 180°

or, 2x + 8 + 2x + 8 = 180°

or, 4x + 16 = 180°

or, 4x = 180 - 16 = 164°

or, x = 164/4 = 41°

<h2>Answer:</h2>

B = 2x + 8 = 2(41) + 8 = 82 + 8 = 90°

<u>B</u><u> </u><u>=</u><u> </u><u>9</u><u>0</u><u>°</u>

Which term of the sequence 114,109,104,...is first negative term

Brrunno [24]

The answer is negative 1. This is because the sequence follows a pattern of the final number being 4, then 9, then 4 again. near the end of the sequence, you will end at the term of positive 4, which when 5 is subtracted from it (the pattern is -5), the first negative term is -1.
