Answer:
Rate of change = -12
Step-by-step explanation:
y − 3 = −12(x + 4)
Expanding, we have;
y - 3 = -12x - 48
y = -12x - 48 + 3
y = -12x - 45
Now, formula for rate of change is;
Rate of change = (y(x + h) - y)/h
y(x + h) is; y = -12(x + h) - 45
This gives;
Rate of change = (-12(x + h) - 45 + 12x + 45)/h
Rate of change = (-12x - 12h - 45 + 12x + 45)/h
Rate of change = -12h/h
Rate of change = -12

Answer:
98
Step-by-step explanation:
The value of the expression below when x=3 and y=8 is 98.
Answer:
a pyramidal prism is 1/3 the volume of a similar rectangular prism of same base and height
so V=(1/3)bh
V=36
H=6
find area of base
36=(1/3)b6
36=2b
divide both sides by 2
18=b
the area of the base is 18 square units
Step-by-step explanation:
3 * (x^2) = 15x
3x^2 -15x = 0
x= - -15 +- sq root (225 -4*3*0) / 2*3
x = [15 +-sq root (225 -4*3*0] / 6
x1 = [15 +15] / 6
x1 = 5
x2 = [15 -15] / 6
x2 = 0
The number is 5
Check
3 * 5^2 = 15 * 5
75 = 75
