Answer:
Ok so right now that is in standard form (Ax+by=C) and we want to get this into y=mx+b form so that we can easily identify the slope. To do that we need to get y alone by folowing these steps:
9x-3y=81
9x-9x-3y=81-9x (in this step we are just getting rid of the x's from the left side so we can get y alone but since we subtract x from that side we need to subtract the same amount of x's on the other)
-3y=81-9x
-3y/-3=81-9x/-3 (finally to get y alone we need to divide by a -3. This is because any negative number multiplied or divided by another negative will give us a positive. If we divide by 3 then y will be negative which is incorrect. We have to divide by -3 on each side)\
y=81-9x/-3 -----> y=-27+3x ( in this part we have to divide everything on the right side of the equation by -3 as we did on the left side. 81/-3 = -27 and -9x/-3 = +3x.
our new equation is y=-27+3x although the proper form is y=mx+b.
all we need to do now is flip the 3x and -27 for this equation to match y-mx+b form. M in the equation represents the slope of an equation.
y=-27+3x---> y=3x-27
in this equation 3 is m and m represents the slope. For an line to be parralel to one another they must have the same slope. Therefore the slope of a line parallel to that equation is 3.
Step-by-step explanation:
The Slope of a line parallel to the line whose equation is 9x – 3y = 81 is 3.
What is the Slope of a line?A slope of a line is the change in y coordinate with respect to the change in x coordinate.
Given that the slope of a line parallel to the line whose equation is
9x – 3y = 81
Reducing the Equation in form of y = mx + c, where m is the slope,
9x - 3y = 81
3y = 9x - 81
y = 3x - 27
Since, two line when parallel have equal slope, so the slope of the given line is 3.
Hence, The Slope of a line parallel to the line whose equation is
9x – 3y = 81 is 3.

What are the solutions of the equation x2-30=x
Answer:
x = 6 or x = -5
Step-by-step explanation:
x^2 - 30 = x
x^2 - x - 30 = 0
(x - 6)(x + 5) = 0
x - 6 = 0 or x + 5 = 0
x = 6 or x = -5

can someone help please i am really confused
Answer:
so here we are told that angle CED is 39 degrees and in this diagram we have three angles the first one is Angle CED the next one is angle CEL and the last one is angle LED so angle c e l + angle LED is equals to angle c e d so in this case 3 x - 6 + x + 25 should be equal to 39 degrees collect the like terms 3 x + x + 25 - 6 is equals to 39 degrees 4X + 19 is equals to 39 cross the 19 over the equals sign that you have 4 x is equals to 39 + 19 4 x is equals to 68 divide both sides by 4 and x is equals to 17 then substitute replace where there is x with seventeen so in this case angle c e l will be 3 * 17 -6 we are multiplying 3 by 17 because it was 3 x and we got the value of x to be 17 so 3 * 17 is 51 -6 is 45 so angle CEL is 45 degrees you can do the same with the other angle that is angle LED and you get x to be 42

The value of the expression is
Answer:
-48 would be the answer
Step-by-step explanation:
product means result of multiplication, so the product of 9x-5=-45 and when it says 3 less than, it means subtraction so we would subtract 3 from -45 which is -48.

What's b/2-14=8 Equal ?
Answer:
1. add 14 to both sides
b/2 = 8E + 14
2. multiply both sides by 2
b = (8E + 14) x 2
3. regroup terms
b = 2(8E + 14)
