3³ - (4² - 2³)
3³ = 3x3x3 = 27
4² = 4x4 = 16
2³ = 2x2x2 = 8
3³ - (4² - 2³) = 27 - (16 - 8) = 27 - 16 + 8 = 19 (answer C)
x+a=3/4
Move a to the other side. Sign changes from +a to -a.
x+a-a=3/4-a
x=3/4-a or x=-a+3/4
Answer: x=3/4-a or x=-a+3/4
2(x+y)=24
2x=y
Use substitution. If y=2x, than we can substitute 2x for it in the other equation, because x and y equal the same things in both equations.
So using that we get 2(x+2x)=24
SIMPLIFY
2(3x)=24
DISTRIBUTE
6x=24.
DIVIDE: x=4.
If we substitute x into the original equations we get x=4 and y=8. Those are your two numbers.
Have a nice day! :)
Answer:
I got (y-7)=1/13(x+6) for point slope
and y=1/3x+13 for slope intercept form
