Answer:
Make a table with values of x and y using the equation y + 3 = -1/4(x - 3) :
x y
0 -2.25
3 -3
5 -3.5
-1 -2
-9 0
Now, graph these and draw a line through the points:
What percent of 19.5 is 70.59?
2 answers:
What always helps me with these type of questions is the formula:
Part Percent
----------- = ---------------
Whole 100
This may seem a little complicated but I'll explain,
70.59 is the full or complete (whole) number
19.5 is (part) of 70.59
And the percent is the unknown part of this so it will stay as a variable. Let's say x
So it comes out to be:
Now that it is set up, you simply multiply diagonally or cross cancel
It should turn out to look like this once you solved it:
70.59x=1950
Then divide 1950 by 70.59
you will then get, x= <span>27.6243093923 or just 27% or 27.6%</span>

Answer:
The answer is x=9 and/or x = -12
Step-by-step explanation:
This is a quadratic formula meaning that you must take the a value (1) b value (3) and the c value (108) and plug it into the quadratic formula.
which simplifies to -3 add or subtract the sqrt of 441 divided by two.
