Answer:

1. No Solution

2. Infinity solutions

3. One Solution

Step-by-step explanation:

1. 2x-3=2(x-1)

distribute the 2

2x - 3 = 2x - 2

2x cancels out

-3 ≠ -2

therefore no solution

2. 3(x - 4) = 2x - 9 +x - 3

distribute and add common factors

3x - 12 = 3x - 12

3x cancels out

-12 = -12

Therefore infinity solutions

3. 2(2x + 3) = 2(3x + 2)

distribute

4x + 6 = 6x + 4

minus 6x

-2x + 6 = 4

minus 6

-2x = -2

There for x=1 meaning one solution

A box has a base of 12 inches by 12 inches and a height of 30 inches. What is the length of the interior diagonal of the box? Ro

Butoxors [25]

This is a problem using the Pythagorean theorem.

The square of the length required is 122 + 122 + 302 = 1188

The length is the square root of this number; I will leave it to you to extract the square root.

Please help! If the two triangles are similar, which equation represents the value of side x?

madam [21]

$x=\frac{p q}{m}$ equation represents the value of side x.

Solution:

The two triangles are similar.

If two triangles are similar, then the corresponding sides are in proportional.

$$\Rightarrow \frac{m}{p} =\frac{q}{x}$

Do cross multiplication.

$$\Rightarrow mx=pq$

Divide by m on both sides.

$$\Rightarrow \frac{mx}{m} =\frac{pq}{m}$

$$\Rightarrow x =\frac{pq}{m}$

Therefore, $x=\frac{p q}{m}$ equation represents the value of side x.

Graph and write solution: 2x + 1 = y -4x + 6y = -10

PIT_PIT [208]

The graph is shown in figure below

The Solution Set is (-2,-3)

Step-by-step explanation:

We need to graph the equations and writ the solution.

For graphing we need to find the values of x and y.

For that, we need to solve the given equations:

$2x + 1 = y\\-4x + 6y = -10$

Let:

$2x + 1 = y\,\,\,eq(1)\\-4x + 6y = -10\,\,\,eq(2)$

We can solve this by using Substitution Method.

Putting value of y of eq(1) into eq(2) and finding value of x:

$2x + 1 = y\,\,\,eq(1)\\-4x+6(2x+1)=-10\\-4x+12x+6=-10\\8x+6=-10\\8x=-10-6\\8x=-16\\x=-16/8\\x=-2$

So, value of x = -2

Now put value of x in eq(1) to find value of y:

$2x + 1 = y\\2(-2)+1=y\\-4+1=y\\y=-3$

So, value of y = -3

Plotting on graph: x=-2 and y = -3

The graph is shown in figure below

The Solution Set is (-2,-3)
