A and E.
x= (1+ root-71)/6 and x= (1-root-71)/6
Answer:
5
Step-by-step explanation:
solve equation 180+92x= 250+78x
Line B
Explanation:
The slope is negative so the line is going to the left. The y-intersect is 1.
Answer:
Student 1.
Step-by-step explanation:
Okay, for this one, for it to be linear, the x has to be adding or subtracting the same amount each time (same goes for y). You have to remember that the x and y do not correspond, only the sides themselves. As you can tell, Student 1 goes up by 1 on the x side each time, and on the y side, it goes up by 5 each time. The other graphs don't have linear equations. I hope this helped, if you need me to evaluate more, just ask!
I'm not sure what you mean by the five step plan, but to get the answer, just think about the clues.
(c = number of cats)
8 fewer dogs than cats can be written: c - 8
since we know how many dogs there are: c - 8 = 12
Now, just solve for the variable: c = 20
Hope I helped :)
