Answer:

y=-3/2x-1

Step-by-step explanation:

First, we convert the equation into slope-intercept form, so that we can make it easier to find the equation of the perpendicular line. Multiply 2/3 by both x and 3, and you get y-3=2/3x+2. Now we subtract 3 from both sides to get y by itself. We are now left with y=2/3x-1. To find the reciprocal of an equation, you look at the slope (in this case it is 2/3) and you find the opposite reciprocal of it. Basically, we take 2/3 and we flip it and change the sign. The equation we are left with is y=-3/2x-1. We didn't use the x-intercept because it wasn't necessary in this case.

Answer:

Step-by-step explanation:

Given

Balloon in the east makes an angle of elevation of $36^{\circ}$ and is at height of 461 m

Balloon in the west makes an angle of elevation of $51^{\circ}$ and is at height of 296 m

Erica height is 1.6 m tall so net altitude of Red balloon is 459.4 m

and net height of Blue balloon is 294.4 m

using trigonometry

$\tan 36=\frac{459.4}{d_1}$

$\tan 51=\frac{294.4}{d_2}$

$d_1=632.30 m$

$d_2=238.4 m$

Distance between two Balloons

$d=d_1+d_2$

$d=870.70 m$

For what value of the variable will<br> b<br> the value of 3−5c be 1 less than the value of 1−c?

Crank

Answer:

c = 3/4

Step-by-step explanation:

Lets set up an equation.

You can get

3-5c + 1 = 1-c to show that it is one less.

now we can solve it.

So by combining like terms, we get:

4-5c = 1-c

that then becomes:

3-5c = -c

--> 3 = 4c

--> c = 3/4
