You add the second equation to the first which eliminates x and leaves you with 2y=18 so you divide 18 by 2 which is 9 so y=9 now you fill in one question for y so do x+4(9)=9 you get x+36=9 now subtract 36 from 9 and you get -27 so x=-27 and y=9
Answer:
92 cm
Step by step explanation:
first: you divide the rectangle into two right angled triangles using the diagonal
secondly:
you use pythagoras theorem to find the width of the rectangle
110²= 60²+ w²
w²= 110²- 60²
w²= 12100- 3600
w²= 8500
w= 92.195
w= 92 cm
Answer:
-x,y?
Step-by-step explanation:
if it's being reflected across the y-axis then that should go in to the negative side of the graph and the same if its being reflected across the x-axis, in which case it would be x,-y
