Answer:

-10/5 for green line aka -2x

and the parallel line would be the same -2x

the equations would be

y= =2x- 6

and the other would be

y= -2x-6

(this should be right)

Solve the linear system of equations using the linear combination method. 4x-9y=20 2x-6y=16

maxonik [38]

The solution is (-4,4)

Step-by-step explanation:

Given equations are:

$4x-9y = 20\ \ \ \ Eqn1\\2x-6x = 16\ \ \ \ Eqn2$

In linear combination method, we have to make coefficients of any one variable opposites by multiplying with an integer

So multiplying 2nd equation by -2

$-2(2x-6y=16)\\-4x+6y=-32\ \ \ \ Eqn3$

Adding Equation 1 and Equation 3:

$4x-9y-4x+12y = 20-32\\3y = -12$

Dividing both sides by 3

$\frac{3y}{3} = \frac{-12}{3}\\y = -4$

Putting y=-4 in equation 1

$4x-9(-4) = 20\\4x +36= 20\\4x = 20-36\\4x = -16$

Dividing both sides by 4

$\frac{4x}{4} = \frac{-16}{4}\\x = -4$

Hence,

The solution is (-4,4)

A truck rental is $30 plus $.30 /mi. Find out how many miles Ken traveled if his bill was $55.20 .

tangare [24]

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

Let's consider the information given:

rental price: $30 + $0.30/mile
total bill for Ken: $55.20

Let's setup an equation for the cost

set 'x' as number of miles traveled

$\hookrightarrow Cost = 30 + 0.3x$

set that equal to the total cost or bill and solve

$30 + 0.3x = 55.2\\0.3x = 25.2\\x=84$

Ken must have traveled 84 miles

Answer: 84 miles

Hope that helps!
