Consider the equation |1/4+12|=x/2.Without calculating, how do you know x=-16 is an extraneous solution?

Without calculating, you can immediately see the absolute value sign, which implies that the final result (x) should be positive, not negative.

Determine whether each scale factor produces an expansion or a contraction under a dilation of the original image

blondinia [14]

Answer:

see the explanation

Step-by-step explanation:

we know that

If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image

If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image

Verify each value

1) -4

$\left|-4\right|=4$

$4> 1$

therefore

The dilation produces an expansion of the original image

2) 0.25

$\left|0.25\right|=0.25$

$0.25 < 1$

therefore

The dilation produces a contraction of the original image

3) -2/3

$\left|-2/3\right|=2/3$

$2/3 < 1$

therefore

The dilation produces a contraction of the original image

4) 2.3

$\left|2.3\right|=2.3$

$2.3 > 1$

therefore

The dilation produces an expansion of the original image

Help need help on slopes

arsen [322]

Answer:

Y= 5/6x+5

Step-by-step explanation:

Okay same as before

the slope is rise over run

The rise is 5

The run is 6

So 5/6

And since ts rising from left to right its positive

The y-intercept which is the first point the line touches the Y axis is 5

So y=5/6x+5
