Answer:
3x+4
Step-by-step explanation:
f(x) = - x+4
Substitute in x=-3x
f(-3x)= - (-3x) + 4 = 3x+4
4y=5x+8
5y=-2x+30
the y always goes first. then the equal sign. next is x and finally just the digit which is also known as "b".
I hope this helps you
QR=WS=2.93
RS=QW =2.04
QS=XR =2.28
RS=XQ=2.04
SY=QR =2.93
RY=QS =2.28
XY=XR+RY=2.28+2.28=4.56
XW=XQ+QW=2.04+2.04=4.08
WY=WS+SY=2.93+2.93=5.86
Perimeter of XYW=XW+WY+XY
Perimeter of XYW=4.08+5.86+4.56
Perimeter of XYW =14.5
The correct answer to 820/42= 19.52 (rounded answer would be 20). I hope I helped :)
