Here's a graph of a linear function. Write the
madam [21]

The equation of the line in slope-intercept form is y = (1/2)x + 3 and the slope is 1/2.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\rm m =\dfrac{y_2-y_1}{x_2-x_1}\\

As we can see in the graph the line goes from (-6, 0) and (0, 3)

Finding the slope:

\rm m =\dfrac{3-0}{0-(-6)}\\

m = 3/6 = 1/2

y = mx + c

y = (1/2)x + c

c is the y-intercept

c = 3

The equation:

y = (1/2)x + 3

Thus, the equation of the line in slope-intercept form is y = (1/2)x + 3 and the slope is 1/2.

Answer:

-3

Step-by-step explanation:

1. rearrange so it's in the formula y=mx+C

2. y=-3x+5

y=mx+C

M=gradient

-3=m

Two cruise ships leave the same port with a 35° angle between their path. Cruise A is traveling at 18 miles per hour and Cruise
GuDViN [60]

Answer:

20\:\mathrm{miles}

Step-by-step explanation:

After travelling two hours, the two cruise ships form a triangle. One of the legs  of this triangle will be the distance Cruise A travelled, and another will be the distance Cruise B travelled. We can find the distance they travel using:

s=\frac{d}{t}, d=s\cdot t

Cruise A is travelling at 18 miles per hour for 2 hours. Therefore, Cruise A has travelled:

d=s\cdot t=18\cdot 2=36\:\mathrm{miles}

Cruise B is travelling at 15 miles per hour for 2 hours. Therefore, Cruise B has travelled:

d=s\cdot t=15\cdot 2=30\:\mathrm{miles}

Because we are given the angle between these legs, we can use the Law of Cosines to find the third leg. The Law of Cosines is given by:

c^2=a^2+b^2-2ab\cos C, where a, b, and c are interchangeable. Let c represent the distance between the two cruises. We have:

c^2=36^2+30^2-2\cdot36\cdot30\cdot \cos 35^{\circ},\\c^2=426.63,\\c\approx \fbox{$20\:\mathrm{miles}$}(one significant figure).

Please Help 100 points Answer all please
Gemiola [76]

A. Yes

B.  Because the three inside angles of both triangles would be identical.

C. Set up a ratio:

 121/22 =  AB/30

Solve for AB:

AB = (121 * 30) / 22

AB = 3630 / 22

AB = 165 ft.
