Find 2 "easy" points on the graph, and identify their coordinates. One such point would be (-4,1) and another would be (4,2).
run = 8 (from -4 to +4)
rise = 2 (from 0 to 2)
rise 2
slope = ------- = -------- = 1/4 y-intercept is (0,1)
run 8
equation of this line is thus y = mx + b, or y = (1/4)x + 1 (answer)
The decimal value of 4/11 is 0.36 repeating.
For this case we have the following polynomial:

Rewriting the polynomial we have:

From here, we can solve the polynomial using the quadratic equation
We have then:





Therefore, the solutions are:


Answer: Yes, it will be enough.
Step-by-step explanation:
I will answer this in English:
We have 27 students and 81 units, we want to give 3 units to each student.
This is only possible if the quotient betwen 81 and 3 must be bigger than 27.
Lets do it:
81/3 = 27
So we have exactly enough for the 27 students.
Answer= 2/3
5 2/3= multiply 5x3=15, then 5x2=10 which makes the fraction: 10/15, simplify by finding the highest common denominator that divides 10 & 15 equally, which would be 5,
5 divided into 10 is 2. 5 devided into 15 is 3 which makes your answer, 2/3.
not 100%, but it makes sense to me...
