You would use the point-slope equation of y-y₁=mx(x-x₁)
So the rate of change is the slope and equals m, so m=-4
and has a solution at (-5,2) which would be the (x₁, y₁) and then it is just plugging in the numbers
y - (2) = (-4)(x - (-5))
y - 2 = -4 (x+5)
y - 2 = -4x - 20
y = -4x - 18
Answer: 5 benches and 23 students
Step-by-step explanation:
I will answer in English.
We have E students and B benches.
If we sit 4 students per bench, we have 3 students left.
then:
E = 4*B + 3
And if we sit 5 students per bench, there are two places with no students sited.
E = 5*B - 2
now we can replace the E in the second equation with the right part in the first equation:
4*B + 3 = 5*B - 2
3 + 2 = 5*B - 4*B
5 = B
So we have 5 benches, and:
E = 4*5 + 3 = 23 students.
Answer: Bro write the question better
Step-by-step explanation:
12/6 + 2/3 + 3/4
MMC of 6, 3 and 4 is 12
So 24+8+9/12 = 41/12 = 3,41 approximately.
Answer:
1) a = 1.6 2) f = 0.53
Step-by-step explanation:
1) 6a = 10 2) 48 = 90f
6a/6 = 10/6 90f/90 = 48/90
a = 1.6 f = 0.53
sorry i could only do the first two, i think those are right
