Answer: x can equal any number

Step-by-step explanation:

3x + 15 = 2x + 10 + x + 5

First, combine the like terms on the right side

2x + x = 3x

10 + 5 = 15

3x + 15 = 3x + 15

Subtract 15 from both sides

3x = 3x

Divide each side by 3

x = x

This means that x can equal any number, and the equation will always be true.

Answer:

The equation is true.

Step-by-step explanation:

Simplify. Combine like terms:

3x + 15 = (2x + x) + (10 + 5)

3x + 15 = (3x) + 15

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:

3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)

3x - 3x = 15 - 15

0 = 0

~ True. The two expressions are equal to each other.

What function represents this graph??
mr Goodwill [35]

The required piecewise function that represents the graph is given as:

f(x)=\left \{ {{y = -3x-10} \atop y=-\frac{1}{2}x-3 } \atop y=-2x-6 }} \right.

<h3>Piecewise functions</h3>

The graph consists of 3 lines with different equations and slopes. In order to determine the function it represents, we will create a piecewise function.

For the line crossing the negative x-axis

Using the coordinate points (-4, 2) and (-2, -4)

Slope = -6/2

Slope = -3

2 = -3(-4) + b
2 - 12 = b

b = -10

The equation of the line will be y = -3x-10

For the line crossing the negative y-axis

Using the coordinate points (-2, -4) and  (2,-2)

Slope = 2/4

Slope = 1/2

-2 = 1/2(2) + b
-2 - 1 = b

b = -3

The equation of the line will be y = -1/2x-3

For the line crossing the positive x-axis

Using the coordinate points (2, -2) and (3, 0)

Slope = 2/1

Slope = 2

0 = 2(3) + b
0 - 6 = b

b = -6

The equation of the line will be y = 2x-6

The required piecewise function that represents the graph is given as:

f(x)=\left \{ {{y = -3x-10} \atop y=-\frac{1}{2}x-3 } \atop y=-2x-6 }} \right.

Tju [1.3M]

Answer:

<h2>         r = 7 in </h2>

Step-by-step explanation:

h = 2 in ,    V = 157 in³

V = π r² × h

157 = π r² × 2

157 = 2π × r²

r^2=\dfrac{157}{2\pi}\\\\r=\sqrt{\dfrac{157}{2\pi}}\ in=7.0692...\ in\approx7\ in
