I believe this is scale factor? SF=new/old. 10/8= a scale factor of 1.25 (the image gets 1.25x bigger). To find x, multiply 5 by 1.25 and subtract the original length of 5 (you subtract this length because x is only the value of the new part of the triangle). X=6.25-5, X=1.25. Try to find y yourself using this scale factor. (Brainliest would be appreciated)
Slope: -4/10 = 4/-10

IF you are asking for the answer to 12 x 3 then your answer will be 36.
The total grade in her first 6 exams
(49+74+75+60+70+77)=405
The total grade she needs to pass
60x7=420
420-405=15
She must receive 15 to pass
