One way to determine the scale factor of a dilation is if you are using a graph then you can pick two corresponding points of the before and after and divide them and you can get the scale factor.

The second one is true because if you have 2 angle measures then you can automatically find the third because we know that all the angles of a triangle add up to 180 so lets say that one angle is 94 degrees and another is 38 degrees we would add those two up to get 132 and then we would subtract that from 180 to get the third angle which would be 48 degrees.

The third one, vertical angles have a common vertex, but they are never adjacent angles. Also, vertical angles are always congruent.

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

Karen has 1/6 of her drink left and Michelle has 2/16 of hers left. Who has more?

Trava [24]

Karen has more of her drink left

This is because she has 1/6 of her drink left,while Michelle has 2/16, or 1/8 of her drink left.

Since 1/6> 1/8, Karen has more of her drink left

Hope this helps :)
