Answer:

4

Step-by-step explanation:

The general equation circle is

{x}^{2}  +  {y}^{2}   = {r}^{2}

Where r is the radius

Plug in the equation

{x}^{2}  +  {y}^{2}  = 16

Take the sqr root of 16 tocfind the radius

\sqrt{16}   = 4

Solve the following system of equations. 3x+4y=12
Lesechka [4]

Answer:

(0,3) is the solution set for given system.

Step-by-step explanation:

Given that:

3x+4y=12  ------- eq1

2x-3y= -9 ------- eq2

Multiplying eq1 with 2 and eq2 with 3 we get:

6x + 8y = 24 --------- eq1

6x - 9y = -27 -------- eq2

Subtracting eq2 from 1 we get:

17y = 51

Dividing both sides by 17 we get:

y = 3

Putting value of 3 in eq1 we get:

3x + 4(3) = 12

3x + 12 = 12

3x = 0

Dividing both sides by 3

x = 0

So the solution set will be: (0,3)

i hope it will help you.

The rectangular prism has the greatest volume

Rectangular Prism Volume= 72
Triangular Prism Volume = 70

Volume formulas:
(R.Prism) V=l•w•h
(T. Prism) V= b•h

Work:
(R.Prism)

V= 4•6•3
V= 72

(T.Prism)

V= (1/2•4•5)(7)
V= 70

The graph of an absolute value function has a vertex of (2,3) and crosses the x-axis at (−1,0) and (5,0). What is the equation f
frez [133]

Answer:

Option D.

Step-by-step explanation:

The vertex form of an absolute function is

y=a|x-h|+k

where, a is a constant, (h,k) is vertex.

It is given that, vertex of an absolute function is (2,3). So, h=2 and k=3.

y=a|x-2|+3   ...(1)

It crosses the x-axis at (5,0). So put x=5 and y=0 to find the value of a.

0=a|5-2|+3

-3=3a

-1=a

Put a=-1 in (1).

y=(-1)|x-2|+3

y=-|x-2|+3

Now, put y=0, to find the equation for this absolute value function when y=0.

0=-|x-2|+3

Therefore, the correct option is D.
