Answer:

x = 15

Step-by-step explanation:

This involves the Secant and Segments Theorem.

Classify the system of equations -1/2x=3-y -7+y=1/2x-2
miskamm [114]

Answer: Inconsistent.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Solve for "y" in each equation:

<em>Equation 1</em>

-\frac{1}{2}x=3-y\\\\y=\frac{1}{2}x+3

<em>Equation 2</em>

<em> -7+y=\frac{1}{2}x-2\\\\y=\frac{1}{2}x-2+7\\\\y=\frac{1}{2}x+5</em>

<em> </em>

You can notice that the slope of the <em>Equation 1 </em>is:

m_1=\frac{1}{2}

And the slope of the <em>Equation 2 </em>is:

m_2=\frac{1}{2}

Observev that m_1=m_2, then you can conclude that the lines are parallel and the System of equations has No solution.

When there is no solution the classification  of the system of equations is: "Inconsistent".

Han has 10 cubes, each 5 inches on a side. Find the total volume of Han's cudes Express your answer as an expression using an ex
docker41 [41]

Answer:

2 * 5⁴

Step-by-step explanation:

Given :

Number of cubes = 10

Side length, a of each cube = 5

The volume of a cube = (side length)³

Hence, the volume of each of Han's cube = 5³

Therefore, the total volume will be :

Volume or cube * number of cubes

5³ * 10

10 = 2 * 5 = 2 * 5¹

5³ * 2 * 5¹

2 * 5^(3 +1)

2 * 5⁴
