The rate of change is -2
Step-by-step explanation:
The slope-intercept form of a linear equation is y = m x + b, where
- m is the slope which represents the rate of change
- b is the y-intercept which represent the initial value (value y at x = 0)
∵ y = -2x - 1
- The equation in the slope-intersect form, compare it with
the form above
∴ m = -2
∴ b = -1
∵ m represents the rate of change
∴ The rate of change is -2
∵ b represents y at x = 0
∴ The y-intercept is -1
The rate of change is -2

Answer:
40 but 50 coud work
Step-by-step explanation:
Hello!
The volume of a cone is Volume = 1/3πr²h.
V = 1/3π(10)²(9)
= 1/3<span>π100(9)
</span>= 1/3<span>π900
= 300</span>π cm³
Therefore, the volume of this right cone is 300<span>π cm</span>³.
T=5
4=2+2/5t
Subtract 2 from both sides.
2=2/5t
Multiply both sides by 5/2.
t=5
