Answer 1

Answer:

y= -1/4x - 6

Step-by-step explanation:

So the point slop form is y = mx + b, where m is the slope : -1/4, and b is the y-intercept (which we don't know yet).

To find b, all you need to do is plug in -1/4 for m and the point (4, -7) for x and y respectively, giving you:

-7 = (-1/4)(4) + b

Then do some algebra shenanigans: multiply -1/4 by 4 to get -1

-7 = -1 + b

then add the 1 to both sides.

b = -6

Then, you can plug the b and the m back into the problem to give you:

y = -1/4x - 6

Answer 2

Answer:

C

Step-by-step explanation:

Point slope form looks like this: [tex]y-y_1=m(x-x_1)[/tex]

We already have our slope (-1/4)

Our [tex]y_1[/tex] is -7 and our [tex]x_1[/tex] is 4

In this case, our equation would be [tex]y-(-7)=-1/4(x-4)[/tex] and the -(-7) would turn into +7

Therefore, the answer is C

Bearings Problem Solving Question:
From a lighthouse two boats can be sighted. Boat 1 on a bearing of 60° at a distance of 2km and Boat 2 on a bearing of 340° at a distance of 3km.
a) If Boat 1 is in need of assistance, what bearing would Boat 2 need to travel on to reach it?
b) Assuming Boat 1 does not move, how far would Boat 2 have to travel?

Answers

9514 1404 393

Answer:

  a) 123.4°

  b) 3.3 km

Step-by-step explanation:

In (N, E) coordinates, Boat 1 is located relative to the lighthouse at ...

  2(cos(60°), sin(60°)) = (1.0, 1.732) . . . . . km

Boat 2 is located at ...

  3(cost(340°), sin(340°)) = (2.819, -1.026) . . . . . km

So, relative to Boat 2, Boat 1 is located at ...

  (1, 1.732) -(2.819, -1.026) = (-1.819, 2.758) . . . . . km

This is at a bearing of ...

  arctan(2.758/-1.819) = 123.4°

and a distance of ...

  √(1.819² +2.758²) ≈ 3.304 . . . . . km

a) Boat 2 would need to travel on a bearing of 123.4°.

b) Boat 2 would need to travel 3.3 km.

_____

Additional comment

We use (North, East) coordinates so we don't have to do the mental gyrations necessary to translate to and from (E, N) coordinates. The latter would correctly orient a map relative to the X-Y Cartesian plane. The former are equivalent to flipping the map over and looking at it from the back side. This is a "rigid transformation", so angles and distances remain unchanged.

How can you determine the number of solutions of a system of linear equations by inspecting its equations?

Answers

Step-by-step explanation:

To find - How can you determine the number of solutions of a system

              of linear equations by inspecting its equations?

Proof -

There exists three types of solution for a system of linear equations.

1. No solution.

2. Unique solution.

3. Infinite many solutions.

Now,

Let the 2 linear equations are as follows :

y = ax + b

y = cx + d

1. For no solution -

a = c and b ≠d

For example-

y = -2x + 5

y = -2x  - 1

Subtract first equation from second , we get

y - y = -2x - 1 - ( -2x + 5)

⇒0 = -2x - 1 + 2x - 5

⇒0 = -6

Not possible

So, There exist no solution.

2. For unique solution -

a ≠ c and b , d can be any value

For example -

If b and d are same ,

y = 2x - 4

y = -3x - 4

Subtract equation 1st from 2nd , we get

y - y = -3x - 4 - ( 2x - 4)

⇒0 = -3x - 4 - 2x + 4

⇒0 = -5x

⇒x = 0

⇒y = 2(0) - 4 = -4

∴ we get

x = 0, y = -4

If b and d are different

y = 2x - 4

y = -3x + 5

Subtract equation 1st from second

y - y = -3x + 5 - 2x + 4

⇒0 = -5x + 9

⇒-5x = -9

⇒x = [tex]\frac{9}{5}[/tex]

⇒y =2([tex]\frac{9}{5}[/tex]) - 4 = [tex]\frac{18}{5} - 4 = \frac{18 - 20}{5} = -\frac{2}{5}[/tex]

∴ we get

x = [tex]\frac{9}{5}[/tex] , y = [tex]-\frac{2}{5}[/tex]

3. Infinitely many solution -

a = c and b = d

For example -

y = -4x + 1

y = -4x + 1

Subtract equation first from equation second

y - y = -4x + 1 - ( -4x + 1)

⇒0 = -4x + 1 + 4x - 1

⇒0 = 0

Satisfied

So, Infinite many solution possible.

What is the Pythagorean Theorem used for right triangles

Answers

Answer:

The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. The a and b are the 2 "non-hypotenuse" sides of the triangle (Opposite and Adjacent).

Answer:

Step-by-step explanation:

Used t find missing side angles when two sides are present. For example, if you have a short leg and a long leg, you can use the Pythagorean Theorem to find the hypotaneus and vse versa, using it to find the short or long leg if the other two are given.

Answer:

x=6

Step-by-step explanation:

Given: 4(x+4)+2x=52

Distribute.

4x + 16 + 2x = 52.

Simplify.

6x + 16 = 52.

Subtract 16 on both sides to isolate out the variable.

6x = 36

Divide.

x = 6

Answer:

x = 6

Step-by-step explanation:

first we distribute the 4 to the (x + 4) by multiplying 4 times each of those

4x + 16 + 2x = 52

Then, combine like terms:

6x + 16 = 52

then subtract 16 from both sides of your equation

6x = 36

then divide both sides by 6

x = 6
