Answer:
f(x) = -4x + 80
Step-by-step explanation:
You are given two points,
(5, 60) and (10, 40)
in order to get the equation, let's use the form slope-intercept form
m = (y1 - y2) / (x1 - x2)
m = (60 - 40) / (5 - 10)
m = 20/-5
m = -4
Get the x intercept
y = mx + b
60 = (-4)(5) + b
b = 60+20
b = 80
so the equation is
y = -4x + 80
f(x) = -4x + 80
Answer:
10.5
Step-by-step explanation:
27 / 2 = 13.5, 13.5 - 3 = 10.5
Answer:
Step-by-step explanation:
f * h / h = f
p / r * r = p
k + g - g = k
a + b - b = a
