Answer:
Step-by-step explanation:
f(x)=2-x
x=2-y
add y both sides, then subtract x from both sides
y=2-x or f(x)=2-x same thing
Answer:
75%
Step-by-step explanation:

45 x 100 = 4,500
4,500 divided by 60 = 75
Answer:
Step-by-step explanation:
Light is considered to be without mass, but it has energy. According to Einstein, energy can be
equivalently presented as mass. Mass is also affected by gravity, but near planets, this effect is
so small that it can be ignored and so we say that light travels in a straight line.
The above statement does not hold true when light passes near a star. A star possesses a very
high gravity field that bends light such that the change of direction is observed.
Answer:
5y + 2y - 4x + 4x = -7 +14
7y = 7
y = 1
2(1) + 4x = 14
4x = 12
x = 3
Step-by-step explanation:
Using the process of elimination
Add both equations. The 4x will be eliminated since one is positive and one is negative. The equation is left with only the y variable and the constant.
When y is found, input it into the second equation to find x.
