Answer:

This is true because 6 does infact equal 6

Step-by-step explanation:

First see if the solution is true by seeing if x = x

So solve both sides

4-3+5 = -6+8+4

1+5 = 2+4

6 = 6

Line 1 is 1/3

Line 2 is 1/3 as well

Choice 1

Step-by-step explanation:

<u>Rise over run</u>

<em><u>Line 1:</u></em>

$\frac{(7)-(3)}{(6)-(-6)}$

$\frac{4}{12}$

<u>Simplify:</u>

1/3

<em><u>Line 2:</u></em>

$\frac{(2)-(1)}{(-3)-(-6)}$

$\frac{1}{3}$

1/3

1 is Paralell to 2 because they have the same slope

I hope this helps! :D

Pls give thx and brainliest if i’m right!

What are the coordinates of the point (−1, 6) after a reflection across the x-axis?

Agata [3.3K]

The answer would be (-1,-6). Remember that the x-axis runs left to right and the y-axis runs up and down. Therefore, if you were to reflect it, just picture it being flipped over. If you go from (-1,+6) and you reflect it over the x-axis, both points are now in the bottom left quadrant where everything is negative. So, you get (-1,-6) The -1 doesn't change since it was already a -x value before and stayed in a negative area.

ZA and ZB are supplementary angles. If m_A= (5x + 25)° and m

andrew11 [14]

Answer:

B = 70

Step-by-step explanation:

Supplementary angles add to 180

5x+25 + 3x+19 = 180

Combine like terms

8x+ 44 =180

Subtract 44 from each side

8x+44-44 =180-44

8x= 136

Divide by 8

8x/8 = 136/8

x = 17

We want to find B

B = 3x+19 = 3(17)+19 = 51+19 = 70

A balloon is rising at a rate of 6 meters per second from a point on the ground 53 meters from an observer. Find the rate of cha

valentina_108 [34]

Answer:

0.0830 radians per second

Step-by-step explanation:

If θ is the angle of elevation and h is the height of the balloon, then:

tan θ = h / 53

Take the derivative of both sides with respect to time:

sec² θ dθ/dt = 1/53 dh/dt

Use Pythagorean identity:

(1 + tan² θ) dθ/dt = 1/53 dh/dt

Substitute:

(1 + (h/53)²) dθ/dt = 1/53 dh/dt

Multiply both sides by 53²:

(53² + h²) dθ/dt = 53 dh/dt

Given dh/dt = 6 and h = 32:

(53² + 32²) dθ/dt = 53 (6)

dθ/dt = 318 / 3833

dθ/dt ≈ 0.0830

The angle of elevation is increasing at a rate of 0.0830 radians per second.
