X=3.2 I believe that's your answer
X+142 =3x+64
subtract x from each side
142 = 2x+64
subtract 64 from each side
142-64 = 2x
78=2x
divide by 2
78/2 = x
x=39
The number is 39
Answer:
f(x)=2x
Step-by-step explanation:
You can get your (a)term by finding rise/run, and there is no y-intercept so the (b)term is not known. Thus you get f(x)=2x.
a. Dilation of 2nd equation by a factor of 12
b. The systems have the same solution, as dilations do not affect overall coordinates, changing side lengths but not angles
0 to 90 degrees is located in quadrant one. 90 to 180 degrees is located in quadrant two. 180 to 270 degrees is located in quadrant three. 270 to 360 degrees is located in quadrant four. Is this what you were after?
