Write in point-slope form an equation of the line that passes through the

Mathematics
1 answer:
QveST [7]3 years ago
3 0

Answer:

y+6 = - 5(x-4)

Step-by-step explanation:

With the given information, use the point-slope formula y-y_1 = m (x-x_1) to write the equation of the line. Substitute values for the m, x_1, and y_1 to find the answer.

m represents the slope, so substitute -5 in its place. The x_1 and y_1 represent the x and y values of one point the line intersects, so substitute 4 for x_1 and -6 for y_1. This gives the following equation:

y+6 = - 5(x-4)

Pls help. Will mark for CORRECT ANSWER!!
Travka [436]
Y = mx + b
slope(m) = -4
(-2,5)....x = -2 and y = 5
now we sub into the formula and find b, the y int
5 = -4(-2) + b
5 = 8 + b
5 - 8 = b
-3 = b

so ur equation is : y = -4x - 3 <==

What is the length of the unknown leg in the right triangle? A right triangle has a side with length 20 meters, hypotenuse with
galben [10]

The length of the unknown leg of the triangle is 15 m.

<u>Step-by-step explanation:</u>

Length of one leg = 20 m

Length of the hypotenuse= 25m

As it is a right angled triangle we can use pythogoras theorem.

Let the unknown length be y

(20) (20)  + y(y) = (25) (25)

400 + y(y) = 625

y(y) = 225

y = √225

y = 15

The length of the unknown leg is 15 m.

In triangle DEF measurement angle D = 45 degrees meausrement angle E = 63 degrees and EF = 24 inches. What is DE to the nearest
alexandr1967 [171]
Since the angles add to 180°, angle F is 72°.

Using the law of sines,

DF/sin72° = 24/sin45°
x = 32.28

So, did you just guess at A?

This is just an answer from another website, but it should still work.

There are two newborns, Gary and Eric. The future lifetime of Gary is uniformly distributed between 0 to 60 years. The future li
scoray [572]

Answer:

\text{The probability that Gary dies first = }\frac{1}{3}

Step-by-step explanation:

To find the required probability,

We can split the 40 years of Eric into very small pieces of time dt. Now, If Eric dies at time t and Gary dies before Eric, the probability is :

\frac{t}{60}\times \frac{dt}{40}=\frac{t\cdot dt}{2400}

Hence the probability that Gary dies first is  given by :

=\int_{0}^{40}\frac{t}{2400}dt \\\\= \frac{1}{3}
