Step-by-step explanation:
what ? you cannot do even simplest subtractions ?
what is it you don't understand here ?
how such a function works ?
you take every value for x (the input variable or argument), put it in place of the "x" (this is nothing else than a placeholder for the actual values) and then perform the mathematical operations. y is then the result of that.
x = 0
y = 0 - 7 = -7
the ordered pair of (x, y) is (0, -7)
x = 1
y = 1 - 7 = -6
(1, -6)
x = -3
y = -3 - 7 = -10
(-3, -10)
x = -5
y = -5 - 7 = -12
(-5, -12)
Answer:you diddnt attach a graph but it woul have a stating pooint of positive 3 and a slove of up one over 1 so 1/1 +3
Step-by-step explanation:
Y = mx + b
m = (y₂ - y₁)/(x₂ - x₁)
m= (6-3)/(20-5) and m = 3/15 = 1/5. Now calculate b.
To that end plug any of the 2 pairs value, let's take (5,3)
y = (1/5).x + b
3 = (1/5).(5) + b & b= 2
The equation: (1/5)x + 2
Answer:
N(t) = m(X)+c
Step-by-step explanation:
Here, M is slope, also known as gradient, while X is the number which is variable and can keep on changing according to the number of increase, decrease or any other modification to the number of children in the school.
An finally, C is the constant which remains the same whatever the variable is. Therefore C would be equal to 440.
I hope this helps you.
