Answer:

A) y+5=-3/2(x-4)

Step-by-step explanation:

Start by rewriting the equation A into slope intercept form (y=mx+b).

1) Distribute the -3/2 to x and -4:

y+5=-3/2x+6

2) Subtract 5 from both sides:

y=-3/2x+1

Now lets check to see if the equation matches up with the line...

The slope (-3/2) is correct, because every time you go down three, you go across to the right 2!

We also know the y intercept, (1) is correct, because the line crosses the y axis at the point (0,1)

Therefore, the correct answer is A!

xand y are light house. y being 20km due east of x and from a ship due south of x the bearing of y was 055°. what is the distanc

leonid [27]

Answer:

I) |xz| ≈ 28.6 km

II) |yz| ≈ 34.8 km

Step-by-step explanation:

Let's assume that the position of ship due south of x is z (aà pictor representation of the question is attached)

|xy| = 20 km, |xz| = ?, |yz| = ?, θ(y) = 55°

Using Trigonometric ratio - SOHCAHTOA

I) Tan θ = |xz| ÷ |xy| ⇒ Tan 55° = |xz| ÷ 20

|xz| = 20 * Tan 55 = 20 * 1.428

|xz| = 28.56 km

|xz| ≈ 28.6 km

II) Cos θ = |xy| ÷ |yz| ⇒ Cos 55° = 20 ÷ |yz|

|yz| * Cos 55° = 20 ⇒ |yz| = 20 ÷ Cos 55°

|yz| = 20 ÷ 0.574 = 34.84 km

|yz| ≈ 34.8 km

The equation of a circle is given below. What is its center?

svp [43]

Answer:

$( \frac{2}{3}, 0)$

Step-by-step explanation:

The general equation for a circle is

${(x - a) }^{2} + {(y - b) }^{2} = {r}^{2}$

Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0

PLEASE HELP!! The slope of the line below is 2.5. Write the equation of the line in point-slope

Kisachek [45]

Answer:

y = 2.5x

Step-by-step explanation:

y = mx + b

m=2.5 (slope) --> y=2.5x+b

coordinate : (2,5) 2 is the x coordinate, 5 is the y coordinate

to Find b, input the coordinate --> 5 = 2.5(2) + b

5 = 5 + b

0=b

y= 2.5x

This is only since it asked to solve using the point. If you look at the graph, the line intercepts the y-axis at (0,0) so b=0.

hope this helps
