Graph is incorrect.
Find points (x,y)
If x=#, what does y=?
Example:
Y=5x+4
Y=5•0+4
Y=0+4
Y=4
Points:
(0,4)
(-1,1)
(-2,-6)
Also, only draw the line in areas where x≤0
Meaning nothing should be on the right half of the square.
The range means what Y values are possible?
When draw properly, with nothing on the right half, the highest Y value will be 4.
So, the range is y≤4
1/4 is the fraction for the number of parents who prefer year round school.
Answer:
0.91

Answer:
Step-by-step explanation:
The total number of students (32) corresponds to the total number of ratio units (3+5 = 8), so each ratio unit represents 32/8 = 4 students.
The 3 ratio units representing boys will stand for 3×4 = 12 boys.
The 5 ratio units representing girls will stand for 5×4 = 20 girls.
There are 12 boys and 20 girls in Janice's classroom.

<em>Additional comment</em>
I find the above solution to be the easiest.
You can also write a system of equations. Let b and g represent the numbers of boys and girls, respectively.
b/g = 3/5
b +g = 32
Multiplying the first equation by g gives an expression for b that can be substituted into the second equation:
b = (3/5)g
(3/5)g +g = 32
8/5g = 32 . . . . . . . . . . . . . . . . . collect terms
g = (5/8)(32) = 5·4 = 20 . . . . . . multiply by 5/8
b = (3/5)(20) = 3·4 = 12 . . . . . . . find b using the value of g
