5x-3=12x+11
-5x -5x

-3=7x+11
-11 -11

-14=7x
/7 /7

-2=x

So -2

Hope this helps!!

Evaluate the piecewise function for the given values.
adoni [48]

Answer:

f(-3) = -2

f(-2.6) = -2

f(0.6) = 2.4

f(4.5) = 8.5

Step-by-step explanation:

(Whole question:

Evaluate the piecewise function for the given values.

Find f(-3), f(-2,6), f(0.6), and f(4.5) for f(x)={ -2 If x ≤ 0 4x. If 0 <x <1. x + 4. If x ≥ 1)

As the piecewise function shows, the function f(x) has the value of -2 for values of x lesser or equal than 0, has the value of 4x if the value of x is between 0 and 1, and has the value of x+4 for values of x greater or equal than 1.

So, for f(-3), the value of x is lesser than 0, so we have that f(-3) = -2

For f(-2.6), the value of x is lesser than 0, so we have that f(-3) = -2

For f(0.6), the value of x is between 0 and 1, so we have that f(0.6) = 4*0.6 = 2.4

For f(4.5), the value of x is greater than 1, so we have that f(4.5) = 4.5 + 4 = 8.5

What is the base area of a cylinder with a radius of 2
Alex17521 [72]

Answer:

(pi)4 or about 12.57 sq. units

Step-by-step explanation:

The base area of a cylinder is a circle.

Since we know that the radius is 2, we can use the equation A = (pi)r^2 to find the area.

So, using this formula, the area is (2)(2)(pi), about 12.57 sq. units (area is squared!)
