Answer:
Step-by-step explanation:
slope intercept form is y = mx + b
b is the y intercept ( crossing y axis value).... by inspection b = -4
m is the slope of the line, Slope = m = 1/4 note: the slope is positive
the slope equals the 'rise' over 'run'
if the line moves up the slope is positive, if the line moves down the slope is negative
the rise is how many y units does the line go 'up' or 'down'
the run is how many x units does the line go 'left' or 'right'
the rise = 1 Y unit
the run = 4 X units
y = mx + b m =1/4 b = -4
y = (1/4)x + (-4)
y = (1/4)x - 4
graph a line stating at y = -4 and going up (rising) to the right ONE Y Unit for every FOUR X units (the run)
Its 12. Part a was 2 part b was 3
6×2=12
4×3=12
Answer:
If the slashes mean divisions and the x means multiplication, the answer would be 25a²/4/5
Ratio of girls to boys - 2 : 3 (2+3=5)
Total: 623 students.
623 divided by 5 equals 125.
125 times 2 equals 250.
So, 250 girls are enrolled at Lincoln Middle School.
Answer:
$92.55
Step-by-step explanation:
Substitute the value of x, which is in weeks, to 12.
so y = 0.91(12) + 103.47
y = 92.55
