Divide everything by 9 to get y by itself.

So, it looks like it is in slope-intercept form! Yet you need to get "Y" by itself in order it to be y=mx+b (slope-intercept form)

Step 1: 

9y=-6x+42
---    --------- INVERSE OPERATIONS: Divide by 9! 
9         9

y=-6/9x+  42/9 

Step 2: Take your new equation and SIMPLIFY/reduce its fractions.

(all these numbers are multiple of 3, so they can be divided by 3 to turn them into it's most simplest form) 

y=-2/3x+ 14/3

Step 3: Identify your final answer.

y=-2/3x +14/3

What is the slope of the line that passes through (-3,4) and (-3,-4)
suter [353]

Answer:

undefined

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

    = ( -4-4)/( -3 - -3)

   = ( -4-4)/( -3+3)

   = -8/0

When we divide by zero, the answer is undefined so the slope is undefined

Solve for x:
pentagon [3]

Answer:

2<x<3

Step-by-step explanation:

4x-4<8 AND 9x+5>23

Solve the first inequality

4x-4<8

Add 4 to each side

4x-4+4 <8+4

4x<12

Divide by 4

4x/4 <12/4

x <3

Solve the second inequality

9x+5>23

Subtract 5 from each side

9x+5-5>23-5

9x >18

Divide by 9

9x/9>18/9

x>2

Put together

x<3 and x>2

2<x<3

sineoko [7]

Multiplication was invented to help you avoid the tedium of adding ...

... $5.25 + 5.25 + 5.25 + ... + 5.25 . . . . . a total of 207 terms

It lets us figure such a sum by computing 207 × $5.25 = $1,086.75

Carl's pay for the week will be $1086.75.
