With no answer choices given, I'd say that 17,000 - 6,000 = 11,000 is a reasonable response.

What is an equation of the line that passes through the point (1,-3) and is perpendicular to the line x+3y=21?
andreev551 [17]

Answer:

3x - y = 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + 3y = 21 ( subtract x from both sides )

3y = - x + 21 ( divide all terms by 3 )

y = - \frac{1}{3} x + 7 ← in slope- intercept form

with slope m = - \frac{1}{3}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{1}{3} } = 3 , thus

y = 3x + c ← is the partial equation

To find c , substitute (1, - 3) into the partial equation

- 3 = 3 + c ⇒ c = - 3 - 3 = - 6

y = 3x - 6 ← in slope- intercept form

subtract y from both sides

0 = 3x - y - 6 ( add 6 to both sides )

6 = 3x - y , that is

3x - y = 6 ← in standard form

ipn [44]

Answer: 2 cars and 6 buses.

Step-by-step explanation:

x + y = 8

5x + 55y =

5 times 2 = 10

plus

55 times 6 = 330

Add 330 plus 10 = 340!

AURORKA [14]
Two different things u can do
Substitution:
X-9y=12
+9y +9y
X=9y+12

-3(9y+12)+9y=36
-27y-36+9y=36
+36 +36
-18y = 72
/-18 /-18
Y = -4


Or whatever this other I’ve is called

-3x-9y=36
-1(X-9y)=(12)-1

-3x-9y=36
-x+9y=-12

-4x=24
X= -6
