Given: \textsf{45 + x = 75}

Need:  \textsf{The value of the unknown x}

Solution:  In order to solve for the unknown we must subtract 45 from both sides which would isolate x and given us the value.

<u>Subtract 45 from both sides</u>

  • \textsf{45 - 45 + x = 75 - 45}
  • \textsf{x = 75 - 45}
  • \textsf{x = 30}

After simplifying the expression we were able to determine that x is equal to 30.

What is the slope of a linear that is perpendicular to the line y=-1/2x+5?​
Vlada [557]

Step-by-step explanation:

Equation of given line is:

y =  -  \frac{1}{2} x + 5 \\  \\ equating \: it \: with \: y =m_1x + c  \\ we \: find \:  \\ m_1 = -  \frac{1}{2} \\ let \: m_2 \: be \: the \: slope \: of \: required \: line \\  \\  \therefore \: m_1 \times m_2 =  - 1( \because \: lines \: are \:  \perp) \\  \\ \therefore \: -  \frac{1}{2} \times m_2 =  - 1\\  \\ \therefore \: m_2 = 2 \\

Thus, the slope of required line is 2.

Solve using any method. −2x+y=−3 x+y=3 ( 5, 2) ( 1, 2) ( 2, 5) ( 2, 1)
nignag [31]

Answer:

Therefore the solution set is (x , y) = ( 2 , 1 )

Step-by-step explanation:

Given:

-2x+y=-3  ...............Equation ( 1 )

x+y=3\\  ...............Equation ( 2 )

\therefore y=3-x     ...............Equation ( 3 )

To Find:

x = ?

y = ?

Solution:

Using Substitution Method we will have

Substitute  above ' y ' Equation 3 in Equation 1 we get

-2x+(3-x)=-3\\-2x-x=-3-3\\-3x=-6\\3x=6\\x=\dfrac{6}{3}=2\\\\x=2

Now Substitute  ' x ' in Equation 3 we get

y=3-2=1\\y=1

Therefore the solution set is (x , y) = ( 2 , 1 )
