Simplify is 26+6x
Answer:
i cant really see the question but ill guess 4 or 4.065
Answer:
The scale factor for a model is 5 cm = 16.05 cm.
Step-by-step explanation:
Given:
Model: 9.5cm Actual : 30.5m and the scale factor for model is 5 cm.
Now, we need to find the actual shape for the scale factor 5 cm.
<em>Let the actual shape be
.</em>
Now, for getting the actual shape we set for proportion:
5:x :: 9.5:30.5
5:x = 9.5:30.5
Then, convert it into fractions:

Now, <em>on cross multiplying we get:</em>

Dividing both sides by 9.5 we get:

Therefore, the scale factor for a model is 5 cm = 16.05 cm.
The slope of the line is -7/4.
The formula for slope is:

lets say (1,9) 1 is x1 and 9 is y1
(-3,16) -3 is x2 and 16 is y2
which equal
