Answer
hello :
note : The equation of a linear function in point-slope form is : y – y1 = m(x – x1)
The point is A (x1 , y1)
Step-by-step explanation:
in this exercice : m = 5 x1 = 0 y1 = -3
the equation of a line in slope-intercept form for a line is :
y - ( -3) = 5 ( x - 0)
y +3 = 5 ( x - 0)
So, all you would do is use distribution.
For example: D is .5(x+3) = -3(x-.5)
you would do
.5 times x+3, which equals .5x+ 1.5
So, .5x+1.5=-3x+1.5
because -3*x-.5 is -3x+1.5.
Then, you would just get x by itself.
.5x+1.5=-3x+1.5
add 3 over to .5 = 3.5x;
subtract 1.5 over to 1.5 = 0
now you have 3.5x = 0
divide by 3.5 to get x by itself and you get zero.
x=0
When you substitute it in, you should have them both equal to each other. I hope this helps. :)
1/27 = 3^(-3)
3^(3x+6) = 3^(-3)
When bases are the same, all you need to do is set the exponents equal to each other:
3x+6 = -3
3x = -9
x = -3

Because it can't be simplified.
There aren't like terms and there isn't fractions.
