QUESTION 1

SVEN [57.7K]

Answer:

1)

1st Error: In going from Step 3 to Step 3.

Reason: Negative sign is not distributed inside the brackets.

2nd Error: In going from Step 5 to Step 6

Reason: Sign of the number is not changed while moving to other side of inequality,

2)

a) 12=-4(-6x-3) and x+5=-5x+5

b) -(7-4x)=9 and 5x+34=-2(1-7x) and -8=-(x+4)

Step-by-step explanation:

Question 1)

The given inequality is:

$\frac{5}{12}-\frac{x-3}{6} \leq \frac{x-2}{3}$

Step 1: Making the denominators common for all fractions

$\frac{5}{12}-\frac{2}{2} \times \frac{x-3}{6} \leq \frac{4}{4} \times \frac{x-2}{3}$

This step is done correctly in the given solution.

Step 2: Simplifying

$\frac{5}{12}-\frac{2x-6}{12}\leq \frac{4x-8}{12}$

This step is done correctly in the given solution

Step 3: Multiplying both sides by 12, and simplifying.

$5-(2x-6)\leq 4x-8\\\\ 5-2x+6\leq 4x-8$

First error is made in this step. While opening the brackets, the negative sign should be distributed inside the bracket, which will change the signs.

Step 4: Simplification:

$11-2x\leq 4x-8$

Step 5: Moving Common terms to one side and simplifying

$-2x-4x\leq -8-11\\\\ -6x\leq -19$

Error was made in this step. When a number is moved to other side, its sign will be changed.

Step 6: Dividing both sides by -6

$x\geq \frac{19}{6}$

Conclusion:

1st Error: In going from Step 3 to Step 3.

Reason: Negative sign is not distributed inside the brackets.

2nd Error: In going from Step 5 to Step 6

Reason: Sign of the number is not changed while moving to other side of inequality,

Question 2:

In the Equation 2: 12=-4(-6x-3), when -4 will be multiplied inside the brackets, the 12 on eft hand side will cancel the 12 that will appear on right hand side, giving a result that will lead to x = 0.

Same is the case with Equation 6: x+5=-5x+5, 5 on both sides will cancel out leaving x = 0.

So, 2nd and 6th equations will have the same solution.

In Equation 1, on expanding the bracket and moving 7 to other side, we get a relation: 4x = 16

In Equation 3, on simplifying the right hand side, and carrying common terms to one side, we get the relation: - 9x = -36

In Equation 5, on expanding the bracket and simplifying the relation is reduced to 4 = x

It can be observed that all these 3 equations have the same solution i.e. x = 4

So, the following set of Equations have the same solution:

a) 12=-4(-6x-3) and x+5=-5x+5

b) -(7-4x)=9 and 5x+34=-2(1-7x) and -8=-(x+4)

Thank you in advance.

zysi [14]

Answer:

y = 1/3x - 8

Step-by-step explanation:

First you solve:

3x + y = - 5

Then subtract x since we're looking for y on both sides of the ( = ):

3x + y = - 5

-3x -3x

Making it:

y = -3x - 5

and then you make the slope ( m ) positive , like so :

1/3

then set up the equation :

y - y1 = m ( x - x1 )

and fill in the points they gave you :

( 3, -7 )

^x1 ^y1

Like this :

y - y1 = m ( x - x1 )

y + 7 = 1/3 ( x - 3 )

y + 7 = 1/3x - 1

-7 -7

y = 1/3x - 8

( If you have the calculator for it , you could always put the equation in and check if it goes through the point )

Which is a solution to the equation |10-5y|=20 y=2 y=4 y=6 y=10

Pavlova-9 [17]

Answer:

y=6

Step-by-step explanation:

|10-5y|=20

Since the absolute value is isolated, we can then separate the equations

For absolute values, there is a positive and negative when we remove the absolute values.

10-5y = 20 10-5y= -20

Subtract 10 from each side

10-10-5y = 20-10 10-10-5y= -20-10

-5y = 10 -5y = -30

Divide by -5

-5y/-5 =10/-5 -5y = -30/-5

y =-2 y =6
