Answer:

x = 16

Step-by-step explanation:

4x+45=3x+61

Subtract 3x from each side

4x-3x+45=3x-3x+61

x+45 = 61

Subtract 45 from each side

x+45-45 = 61-45

x =16

The piecewise defined function is

f(t) = 800 * 1.5^t for 0 - 2

f(t) = 2700 * 1.05^t-3 for 3 to 9

<h3>How to determine the piecewise functions?</h3>

On the domain of t = 0 to 2, we have:

f(0) = 800

f(1) = 1200

f(2) = 1800

The above function is a piecewise function with the following definition

f(0) = 800 --- initial value

r = 1200/800 = 1.5 --- rate

The function is then represented as:

f(t) = f(0) * r^t

This gives

f(t) = 800 * 1.5^t

On the domain of t = 3 to 9, we have:

f(3) = 2700

f(4) = 2835

The above function is a piecewise function with the following definition

f(3) = 800 --- initial value

r = 2835/2700 = 1.05 --- rate

The function is then represented as:

f(t) = f(3) * r^t-3

This gives

f(t) = 2700 * 1.05^t-3

Hence, the piecewise defined function is

f(t) = 800 * 1.5^t for 0 - 2

f(t) = 2700 * 1.05^t-3 for 3 to 9

Which equation represents a circle with the same radius as the circle shown but with a center at (-1,1)
Alex_Xolod [135]

Answer:

(x + 1)² + (y - 1)² = 16

Step-by-step explanation:

Since the standard form for an equation of a circle is

<h3> (x - h)² + (y - k)² = r²</h3>

The (h,k) are co-ordinate of your centre of circle, which in this case is (-1,1) and r is the radius of circle.

As we can see in the figure radius = 4units

<em>from centre(1,-2) to (1,-2)</em>

Put these into the equation

(x + 1)² + (y - 1)² = 4²

(x + 1)² + (y - 1)² = 16

4 - 2x = 10 plz solve
posledela

Answer:

x=7

Step-by-step explanation:

Opposite of subtraction is adding so you do 4+10=14 so that means that x equals seven because 2x7 equals 14.
