Question 2(Multiple Choice Worth 1 points) (01.04 LC) Solve for x: −2x − 4 > 8

frutty [35]

The required solution of the inequality is x < - 6.

Given that,
To solve the equation −2x − 4 > 8.

<h3>What is inequality?</h3>

Inequality can be described as the consideration of the equation including the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
The given equation
−2x − 4 > 8
adding 4 on both sides
-2x > 12
multiply by -1
when multiplying the negative -1 it will change the behavior of the inequality, so.
2x < - 12
Divide by 2 into both sides
x < - 6

Thus, the required solution of the inequality is x < - 6.

Using elimination method

bogdanovich [222]

Answer:

The value of x is 2 and y is (-5)

Step-by-step explanation:

<h3>Given;</h3>

-7x + y = – 19
-2x + 3y = – 19

The value of x and y

<h3>By Using Elimination Method;</h3>

First name the equation

-7x + y = – 19 ...(1)
-2x + 3y = – 19 ...(2)

Now, Multiply equation (1) by 3 we get,

3 × (-7x + y = – 19)

-21x + 3y = – 57

Now, Eliminate

-21x + 3y = – 57

-2x + 3y = – 19

+ – +

-19x = -38

x = -38/-19

x = 2

Now, Put the value of x in equation (2) we get the value of y.

-7x + y = – 19

-7(2) + y = – 19

-14 + y = -19

-14 + 14 + y = -19 + 14

y = -5

Thus, The value of x is (-5) and the value of y is 2.

<h3>For Verification;</h3>

-7x + y = – 19

-7(2) + (-5) = – 19

-14 – 5 = – 19

-19 = -19

-2x + 3y = – 19

-2(2) + 3(-5) = – 19

-4 – 15 = – 19

-19 = -19

Here, L.H.S = R.H.S

Hence Verified!

Pls solve fast pls help

Svetlanka [38]

Answer:

The Answer should be 6%

Step-by-step explanation:

Given,

MP =1500 and Discount =10%

So, SP = 1500 × 90% =1350

We know, profit = $\frac{sp-cp}{cp}$ × 100%

=>20 = $\frac{1350-cp}{cp}$ × 100

=>CP = 1125

Now, if profit =12%

then, SP' = 1260 ;(using previous equation for profit and CP=1125)

So, SP' = MP × (100 -Discount )

∴ Discount = 16% ;(SP' = 1260 and MP = 1500)

So, Discount should be increased = 16% - 10% = 6%

Pls mark this as the brainliest
