Simplify<br>10x - (5x-x)

Alex17521 [72]

<em>Answer:</em>

<em></em> $\boxed{6x}$ <em></em>

<em>Step-by-step explanation:</em>

<em></em> $10x - (5x-x)$ <em></em>

<em>Distribute the Negative Sign:</em>

<em></em> $= 10x + -1 (5x - x)$ <em></em>

<em></em> $= 10x + -1 ( 5x) + -1 (-x)$ <em></em>

<em></em> $= 10x + -5x + x$ <em></em>

<em>Combine Like Terms:</em>

<em></em> $= 10x + -5x + x$ <em></em>

<em></em> $= (10x + -5x + x)$ <em></em>

<em></em> $= 6x$ <em></em>

<em>Hope this helped you!</em>

Where do (3/2,-7) and (-4,5) intercept

Vinil7 [7]

Answer:

The intercept of the given points is - $\frac{41}{11}$

Step-by-step explanation:

Given points as :

( $x_1$ , $y_1$ ) = ( $\frac{3}{2}$ , - 7 )

( $x_2$ , $y_2$ ) = ( - 4 , 5 )

Now, slope of line using given points can be written as :

Slope = m = $\dfrac{y_2 - y_1}{x_2 - x_1}$

or. m = $\dfrac{5 - ( - 7 )}{( - 4 ) - [tex]\frac{3}{2}$ }[/tex]

or, m = $\dfrac{12}{( - 4 ) - [tex]\frac{3}{2}$ }[/tex]

or, m = $\frac{12}{\frac{- 8 - 3}{2}}$

Or, m = $\frac{12}{\frac{- 11}{2}}$

∴ m = $\frac{-24}{11}$

So, The slope of the line using points = m = $\frac{-24}{11}$

now, equation of line in slope intercept form can be written as

y - $y_2$ = m × ( x - $x_2$ )

or, y - 5 = $\frac{-24}{11}$ × ( x - ( - 4 ) )

or, y - 5 = $\frac{-24}{11}$ × ( x + 4 )

Or, 11 × ( y - 5 ) = - 24 × ( x + 4 )

Or, 11 y - 55 = - 24 x - 96

Or, 11 y = - 24 x - 96 + 55

Or, 11 y = - 24 x - 41

∴ y = $\frac{-24}{11}$ x - $\frac{41}{11}$

Now, comparing with slope intercept equation

I.e y = m x + c , where c is the intercept

So, The intercept of points is - $\frac{41}{11}$

Hence The intercept of the given points is - $\frac{41}{11}$ Answer
