Answer:

A) $y+7=-3(x-4)$

Step-by-step explanation:

Hi there!

The given equations are written in point-slope form: $y-y_1=m(x-x_1)$ where <em>m</em> is the slope of the line and $(x_1,y_1)$ is a point that falls on the line

Notice how the line is travelling infinitely down as x increases. This means that the slope is negative.

Therefore, the equation of the line is either A or B.

Now, let's look at A:

$y+7=-3(x-4)$

This equation suggests that the point (4,-7) falls on the line, which it does.

Therefore, the equation of the graph is $y+7=-3(x-4)$ .

I hope this helps!

A young sumo wrestler decided to go on a special diet to gain weight rapidly. He gained weight at a constant rate.

Mamont248 [21]

The wrestler's weight before he went on his diet is 78 kg

<h3>How to find the y-intercept?</h3>

The formula for slope is;

m = (y2 - y1)/(x2 - x1)

Thus, using two points we have;

m = (93.6 - 85.8)/(3 - 1.5)

m = 5.2

At the start of his diet, time in months = 0 months and so x = 0. Thus;

5.2 = (85.8 - y0)/(1.5 - 0)

5.2 * 1.5 = 85.8 - y0

y0 = 85.8 - (5.2 * 1.5)

y0 = 85.8 - 7.8

y0 = 78 kg

Thus, the wrestler's weight before he went on his diet is 78 kg

Find the volume................

Sauron [17]

Answer:

$1) v= 400 ft^{2}$

$2) v=1093.3m^{3}$

Step-by-step explanation:

1) v= 1/3 ab ×h

v= 1/3 (10)(10)×√13²-5²

v= 400 ft²

-------------------

2) v= πr² h/3

v= 1/3 × π×(6)²×29

v= 1/3×π×12×29

v= 348π

v= 1093.27

≈1093.3

A new cruise ship line has just launched 3 new ships: the Pacific Paradise, the Carribean Paradise, and the Mediterranean Paradi

Anton [14]

Let x = Pacific Paradise
You can set up the equation like this:
x + (3x - 25) + (x + 18) = 928
(Combine like-terms)
5x - 7 = 928
(Add 7 to both sides)
5x = 935
(divide by 5 to both sides)
x = 187 (# of deluxe staterooms Pacific Paradise)

Next to find the # of deluxe staterooms of the other cruise ships create two equations

Let y = Carribean Paradise
x + 18 = y
(plug in the value of x which is 187)
187 + 18 = y
(combine like-terms)
205 = y (# of deluxe staterooms Carribean Paradise)

Let z = Mediterranean Paradise
3x - 25 = z
(plug in the value of x which is 187)
3(187) - 25 = z
(follow PEMDAS to simplify and combine like-terms)
536 = z (# of deluxe staterooms Mediterranean Paradise)

Finally check your answer by adding up all of your answers to make sure it equals 928

536 + 205 + 187 = ? (928!)
