Answer:
x = 1.25, y = 1.75
Step-by-step explanation:
The smaller and larger triangles are similar triangles. (the 2 triangles have the same angles).
We know that the smaller triangle has length 8 for it's bottom side when the larger triangle has length 10. This means the scale factor between the 2 is 10 / 8 which is 1.25. Therefore by multiplying the side lengths of the smaller triangle by 1.25 we get the side lengths of the larger triangle.
5 * 1.25 = 6.25
7 * 1.25 = 8.75
However we don't want the whole side lengths we want x and y, We need to subtract 5 and 7 respectively from the lengths of the larger triangles.
Therefore the lengths must be: 6.25 - 5 = 1.25
and 8.75 - 7 = 1.75
Therefore x and y equal 1.25 and 1.75
Answer:
<em>x</em><em> </em><em>=</em><em> </em><em>6</em>
Step-by-step explanation:
<em>To</em><em> </em><em>attain the</em><em> </em><em>x-intercepts</em><em> </em><em>you</em><em> </em><em>have</em><em> </em><em>to</em><em> </em><em>let</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>0</em><em>.</em>
<em>So</em><em> </em><em>in</em><em> </em><em>this</em><em> </em><em>case you will be</em><em> </em><em>having</em><em>:</em>
<em>4</em><em>x</em><em> </em><em>+</em><em> </em><em>2</em><em>(</em><em>0</em><em>)</em><em> </em><em>=</em><em> </em><em>2</em><em>4</em>
<em>4</em><em>x</em><em>/</em><em>4</em><em> </em><em>=</em><em> </em><em>2</em><em>4</em><em>/</em><em>4</em>
<em>x</em><em> </em><em>=</em><em> </em><em>6</em>
<em>Hopefully</em><em> </em><em>it</em><em> </em><em>makes sense</em><em>.</em>

The percent decrease is found by using the formula (original price - new price)/(original price). The percent decrease is then (2.49 - 1.99)/2.49 = 0.20 = 20%. A percent increase is found by using the formula (new price - original price)/(original price). The percent increase is then (2.49 - 1.99)/1.99 = 0.25 = 25%. The percents of change are not the same. The percent increase is greater.
Answer: 1 and 2 centimeters become 10 and 20 millimeters, while 30 and 80 millimeters become 3 and 8 centimeters.
