Answer:

C 1099

Step-by-step explanation:

The volume of a cylinder is given by

V = pi * r^2 *h

We know the radius is 5 and the height is 14

Substitute in what we know

V = 3.14 * 5^2 *14

V = 3.14 *25*14

V =1099  in^3

I need to find how many solutions does the system have. ​
REY [17]
From what I got there is one real solution :)

Rearrange the second equation to give y=2-2x, substitute into the first equation to give you a value for x and then using that you can work out y for the exact coordinates of intersection :)

Also they are both straight line graphs so they will either have one or no solutions

Hope this helped :)

Answer:

c. a: 4

b: 12

c: 9

4x² +12x+9=0

(2x+3)(2x+3)= 0

(2x+3)²=0 {square root both sides}

2x+3=0

2x=-3

x= -3/2

Need help not sure about my answers
shusha [124]

Answer:

  x = 0, x = 1

Step-by-step explanation:

Both graphs correctly plot f(x).

Only the bottom graph correctly plots g(x).

The points of intersection of f(x) and g(x) are (0, -4) and (1, -2). The x-value of these points are x = 0 and x = 1. These are the values of x for which f(x) = g(x).
