Answer:

 \bold{\text{Slope (m)}=\dfrac{1}{4}}Slope (m)=41

Step-by-step explanation:

A linear equation is of the form: y = mx + b   where

m is the slope

b is the y-intercept (where it crosses the y-axis)

x + 4y = 16

     4y = -x + 16

       y = -\dfrac{1}{4}x+\dfrac{16}{4}y=−41x+416

       y=-\dfrac{1}{4}x+4y=−41x+4

The y-intercept (b) = 4

Next, find the slope given point (4, 5) and b = 4

\begin{gathered}y=mx+b\\\\5=m(4)+4\\\\1=4m\\\\\dfrac{1}{4}=m\\\\\\\\\large\boxed{Slope (m)=\dfrac{1}{4}}\end{gathered}y=mx+b5=m(4)+41=4m41=mSlope(m)=41

If the scale factor between a scale drawing of a rectangle and the real object is 1:3 what would be the ratio of the areas?

Answers

Answer:

The ratio of the areas will be will be 1 : 9

Step-by-step explanation:

The linear scale factor represents a ratio that is used to multiply the dimensions of objects so that accurate geometries can be transferred between real-life and paper.

The linear scale factor is quite different from the area scale factor but related to it in the following way:

The area factor can be obtained by squaring the linear scale factor.

This is Area factor = (Linear scale factor) ^2.

Linear scale factor = (1:3)

Area factor = [tex]1^2 : 3^2[/tex]

Area factor will be 1: 9

Thus, when the linear scale factor is 1:3 the area factor will be 1 : 9

Answer:

55

Step-by-step explanation:

This is 55 because you need to make a sum of 180 when making a line and 125+55=180

Answer:

55 degrees.

Step-by-step explanation:

If you see that it is parallel. You can see that each angle on the top and bottom of it equals 360 degrees. So if the same 360 degree angle is at the bottom of these both. And both of then have 2 180 equalling degrees on the top and bottom of it. Then that would mean for the 125 the other side would have 55 degrees equalling 180. Same for the bottom so that would mean that it would be the same for the bottom 360 degree angle making me absolutely sure that X is equal to 55 degrees.
