Answer:
Step-by-step explanation:
90x - 60y = 68.....multiply by -1
90x - 70y = 91
---------------------------
-90x + 60y = -68 (result of multiplying by -1)
90x - 70y = 91
---------------------------add
-10y = 23
y = -23/10 <===
90x - 60y = 68
90x - 60(-23/10) = 68
90x + 138 = 68
90x = 68 - 138
90x = - 70
x = -70/90
x = -7/9 <=====
Small triangle: <span>The side // x axis has a length of 4
Large triangle: The side // x axis has a length of 12
So Small/Large = 4/12 = 1/3
Small triangle: <span>The side // y axis has a length of 3
Large triangle: The side // y axis has a length of 9
</span><span>So Small/Large = 3/9 = 1/3
So the scale factor to obtain this dilatation is 1/3</span>
