Answer:
2.67
Step-by-step explanation:
y = -19
I started by adding 18 to both sides(inverse operation) then dividing by -2 to isolate the variable. What you do to one side must be done to the other
Answer:
x equals 4.
Step-by-step explanation:
32 divided by 8 equals 4. I'm not sure there's any other evidence lol :)
4 pieces of pipe,
4/3 yd long
25/6 yd long
5 pieces same length.
(25/6)/5 = 5/6 yd is the length of each piece of woods.
These functions are expressed in the factored form: what this means is that say for the first one y=(x-4)(x-1)(2+x)(3+x) ... when x=4, the first bracket becomes 0. Same for x=1, x=-2, x=-3 ...
If you were to graph this, you would see that the function's line interesects the x-axis at these points... when x=4, when x=1, etc etc.
Thus, take a look at the zeroes of the graph. At which x points do they interscet the x-axis? You can determine the equation of your graph by this.
