Graphs can be used to represent functions.

See attachment for the graphs of: <em>y =x - 2, y = 0.4x - 2, y =-x - 2</em>

The function is given as: \mathbf{y = kx - 2}

When k = 1,

We have:

\mathbf{y = 1\times x - 2} ----- substitution property of equations

\mathbf{y = x - 2}

So, the equation is: \mathbf{y = x - 2} when k = 1

When k = 0.4,

We have:

\mathbf{y = 0.4\times x - 2} ----- substitution property of equations

\mathbf{y = 0.4x - 2}

So, the equation is: \mathbf{y = 0.4x - 2} when k = 0.4

When k = -1,

We have:

\mathbf{y = -1\times x - 2} ----- substitution property of equations

\mathbf{y = -x - 2}

So, the equation is: \mathbf{y = -x - 2} when k = -1

See attachment for the graphs of: \mathbf{y = x - 2}, \mathbf{y = 0.4x - 2} and \mathbf{y = -x - 2}

Evaluate 1/3 m- 1- 1/2 n when m=21 and n=12
liq [111]

Answer:

0

Step-by-step explanation:

First we have to identify 1/3 m. We know that m is 21 and 1/3 of 21 is 7.

Then we find 1/2 on n which we know is 12 so 1/2 of 12 is 6.

Then we subtract. 7-1 is 6 and 6-6 is 0

Hope this helped!!! :D

A cylinder and a cone have the same volume. The cylinder has radius x and height y. The cone has radius 2x. Find the height of t
weqwewe [10]
V(cylinder)=πR²H
Radius of the cylinder R=x, height of the cylinder H=y.
We can write for the cylinder
V(cylinder)=πx²y

V(cone) =(1/3)πr²h
Radius of the cone r=2x.
We can write for the cone
V(cone)= (1/3)π(2x)²h=(1/3)π *4*x²h

V(cylinder) =V(cone)
πx²y=(1/3)π *4*x²h
y=(4/3)*h
h=(3/4)*y
