Answer: The value of x is -5 and the value of y is 5.

Explanation:

The slope of the line is \frac{2}{3} and the point is (-2,5) from which the line line is passing.

If a line is passing through the point (x_1,y_1) with slope m, the the equation of line is,

y-y_1=m(x-x_1)

y-5=\frac{2}{3}(x+2)

3y-15=2x+4

3y-2x=19    ..... (1)

It is given that the point A(x,3) and B(-2,y) lies on the line. It means it satisfies the equation of the line.

Put y=3 in equation (1).

3(3)-2x=19

-2x=10

x=-5

The value of x is -5.

Put x=-2.

3y-2(-2)=19

3y+4=19

3y=15

y=5

The value of y is 5.

Can you help me with this question?

Answer: 359 ft

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

Whenever you have a problem like this, you must first make an assumption that the building (in this case the lighthouse) is perpendicular to the ground (or sea).  This allows you to create a right triangle (see attached image).

The angle of depression is the angle from an imaginary perpendicular line passing through the top of the building.  Since that imaginary line is parallel to the ground (or sea), you can use alternate interior angles to place that angle in the triangle.

NOTE: BOTH angle of elevation and angle of depression are placed in the lower corner of the triangle. Don't let the names confuse you!

Now you can use trigonometry to solve ....

In the given problem, we have the side OPPOSITE of the given angle (24°) and need the side ADJACENT to the angle, so we will use tan to solve for x.

tan\ \theta=\dfrac{opposite}{adjacent}\\\\\\tan\ 24^o=\dfrac{160}{x}\\\\\\\rightarrow x=\dfrac{160}{tan\ 24^o}\\\\\\\rightarrow x=359.4\\\\\\\rightarrow x\approx 359

Write an equation and solve.<br> How opd am I if 400 reduced by 2 times my age is 244?
seropon [69]

Answer:

78

Step-by-step explanation:

x = your age

400 - 2x = 244

subtract 400 from both sides of the equation:

-2x = -156

divide both sides by -2:

x = 78

A rectangular soccer field is 6w yards wide
lutik1710 [3]

Answer:

\sqrt{(6w)^2+(10w)^2}

Step-by-step explanation:

You need to use Pythagoras' theorem:

c=\sqrt{a^2+b^2} where a and b are the sides of the field.

So the distance from one corner to the opposite corner = \sqrt{(6w)^2+(10w)^2}
