Answer:
y = ⅘x - 41/5
Step-by-step explanation:
slope of the line from the origin = -5/4
slope of any perpendicular to the line = ⅘
equation of the line from the origin:
y = -(5/4)x
perpendicular to the line that passes through (4,-5):
y+5 = ⅘(x-4)
y = ⅘x - 41/5
Answer:
5*3=k, k=15
Step-by-step explanation:
y=k/x is the inverse variation equation
5=k/3
k=15
Answer:
"A half of a class and a half of a student got A on a test" this confuse me for a bit.... but i hope i got the right answer
Step-by-step explanation:
call number of students in the class is a
A half of a class and a half of a student got A on a test ->1/2 a +0.5 ?
1/2 a + 0.5 + 1 = 2/3 a
-> 1/2 a +1.5 = 2/3 a
-> 1.5 = 1/6a
-> a = 9
i would say its A but im not sure
