Answer:

9. y= -2x+6

10. y= -0.4x+ \frac{1}{3}

11. y = -5x+2

12. y=41

13. y=2x+3

14. y= -4x-39

Step-by-step explanation:

9.

y= -2(x-3)

y= -2x+6

10.

12x+30y=10

<em>Subtract 12x from both sides</em>

30y=10-12x

<em>Divide both sides by 30</em>

y= -0.4x+ \frac{1}{3}

11.

y = -5x+2

(Already solved)

12.

y=6+36-1

y=41

13.

y-3=2x

<em>Add 3 to both sides</em>

y=2x+3

14.

y= -3-4(x+9)

y= -3-4x-36

y= -4x-39

Drag each tile to the correct location on the table. Each tile can be used more than once, but not all tiles will be used. Lewis
son4ous [18]

The fill up for the 3rd  step is y - 250 =  340x.

  • The fill up of the 5th step is x = \frac{y-250}{340}
  • The fill up of the 6th step  is \frac{8750-250}{340} = 25 = x, \frac{8750-250}{340}= 34 = x
  • The justification for the 2nd step is subtraction PE.
  • The justification for the 4th step is division PE.

<h3>What is the simplification  about?</h3>

Note that:

y-250 = 250 + 340 x - 250

y = 250 + 340x.

Make x the subject of the formula:

y - 250 =  340x.

then y-250/340 = x

Then  x = \frac{y-250}{340}

The justification for the second step is subtraction property of equality because it undergoes subtraction and the collection of like terms and then subtracting them from one another as shown below:

y-250 = 250 + 340 x - 250

y= 250 + 340x - 250 + 250

Note that (-250 + 250) = 0

y = 250 + 340x.

Lastly, The fill up of the 6th step is substitution of the amount of money  saved and  then simplifying it.

3ax-n/5=-4 solve for x
jasenka [17]
3ax-\frac{n}{5}=-4\ \ \ |Add\ \frac{n}{5}\ to\ both\ sides\\\\&#10;3ax=-4+\frac{n}{5}\\\\&#10;3ax=-\frac{20}{5}+\frac{n}{5}\\\\&#10;3ax=\frac{-20+n}{5}\ \ \ |Divide\ by\ 3a\\\\&#10;x=\frac{-20+n}{5}*\frac{1}{3a}\\\\&#10;x=\frac{-20+n}{15a}\\\\Asnwer\ is\ x=\frac{-20+n}{15a}.

in recent NBA season Shaquille O'Neal made 60% of his field goals what fraction of his field goals did Shaquille make
KonstantinChe [14]
6/10 or simplified it could be 3/5 shots because 60% is the same a 60/100 so just simplify it down to the lowest common factor
