8x + y = 9 <br> Convert the following equations to standard form
Citrus2011 [14]

Answer:

x=1/8y+9/8    

y=<u>y=−8x+9</u>

Step-by-step explanation:

<u>Let's solve for y.</u>

<u>8x+y=9</u>

<u>Step 1: Add -8x to both sides.</u>

<u>8x+y+−8x=9+−8x</u>

<u>y=−8x+9</u>

<u />

<u>Let's solve for x.</u>

<u>8x+y=9</u>

<u>Step 1: Add -y to both sides.</u>

<u>8x+y+−y=9+−y</u>

<u>8x=−y+9</u>

<u>Step 2: Divide both sides by 8.</u>

<u>8x/8=−y+9/8</u>

<u>x=−1/8y+9/8</u>

Which pair of words describes this system of equations 3y=9x-6 2y+6x=4
pishuonlain [190]

Answer:

Consistent and dependent

Step-by-step explanation:

Given

3y = 9x - 6

2y + 6x = 4

Required

The words that describe the equations

Make y the subject in (2)

2y + 6x = 4

Collect like terms

2y = 4 - 6x

Divide through by 2

y = 2 - 3x

Substitute: y = 2 - 3x in (1)

3y = 9x - 6

3(2 - 3x) = 9x - 6

6 - 9x = 9x - 6

Collect like terms

9x+9x = 6+6

18x = 12

Solve for x

x = \frac{12}{18}

Simplify

x = \frac{2}{3}

Substitute x = \frac{2}{3} in y = 2 - 3x

y = 2 - 3*\frac{2}{3}

y = 2 - 2

y =0

So, we have:

x = \frac{2}{3} and y =0

<em>The system is consistent because it has at least 1 solution</em>

<em>The system is dependent because it has more than 1 solution</em>
