Answer:

y=-\frac{1}{3}x+4

Step-by-step explanation:

step 1

Find the slope of the perpendicular line

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal

(the product of their slopes is equal to -1)

In this problem

we have

y=3x+1

The equation of the given line is m=3

so

the slope of the perpendicular line to the given line is

m=-\frac{1}{3}

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=-\frac{1}{3}

(x1,y1)=(6,2)

substitute

y-2=-\frac{1}{3}(x-6)

Convert to slope intercept form

y=mx+b

Distribute right side

y-2=-\frac{1}{3}x+2

y=-\frac{1}{3}x+2+2

y=-\frac{1}{3}x+4

The diagram shows a triangle ABC where AB=AC , BC=AC, and ⦟BAC = 20 degree, find ⦟ADB​
Mariulka [41]

Answer:

hello something is wrong with the question. if ab= AC, and AC = BC, AB=BC, it'd make this an equilateral triangle and the degree wouldn't be 20 degrees

8x + y = 17<br> 5x + 5y = –20
Diano4ka-milaya [45]

Answer:

X=3 Y=-7

Step-by-step explanation:

You can solve a system of equations a number of ways. Substitution makes the most sense in this case. Take the top equation and set it equal to y making it: y=17-8x

Then substitute y in the bottom equation for the y solved in the top. So,

5x + 5(17-8x) = -20

Then solve for x

x=3

Now that we know x, plug it back into the equation for y

y = 17 - 8(3)

y = -7

So your solution is (3, -7)

You plan to take $450 u.s. on a trip to south africa. how many rands is this if one u.s. dollar equals 3.70 rands?
Inga [223]
$1 = 3.70 rands

$450 is simply 450 times $1, so multiply the conversion equation above by 450 on both sides.

450 * $1 = 450 * 3.70 rands

$450 = 1665 rands
