Answer:

Solution tends to infinity

Step-by-step explanation:

Given the expression

(3x-2)/(x+3)-1=(3x-3)/(x+1)-2

This can also be expressed as;

(3x-2)/x+2 = 3x-3/x-1

3x-2/x+2 = 3(x-1)/x-1

3x-2/x+2 = 3

Cross multiply

3x-2 = 3(x+2)

3x-2 =3x+6

Collect like terms

3x-3x =6+3

0x = 9

x = 9/0

x = infinity

Hence the expression had no solution. It tends to infinity

Rudik [331]

Answer:

(x,y) = (2.-2)

Step-by-step explanation:

Given

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

-2x + y = -6

Solving (a): Graph the equations

See attachment for graph

Solving (b): The solution

This is the point of intersection between both lines

From the attached graph, the point of intersection is:

(x,y) = (2.-2)

A tank has the shape of a rectangular prism with the dimensions shown. How much glass was used to make the tank. 34 in² 65 in² 1
Lady bird [3.3K]

Answer: Find the surface area with the formula SA = 2wl + 2lh + 2hw

Step-by-step explanation:

<u><em> Since you did not provide the figure, I will give you a general explanation about how to solve this exercise.</em></u>

By definition, the surface area of a rectangular prism can be calculated with the formula shown below:

SA = 2wl + 2lh + 2hw

Where "SA" is the surface area of the rectangular prism, "w" is the width of the rectangular prism, "l" is the length and "h" is the height of the rectangular prism.

Therefore, if you know the length, the width and the height of the rectangular prism, you can follow these steps in order to calculate how much glass was used to make the tank. The procedure is:

Step 1: You must substitute the values of "l", "w" and "h" into the formula.

Step 2: Finally, you must evaluate in order to get the surface area of the rectangular prism (This value is the amount of square inches that was used to make the tank).

Answer:

c

Step-by-step explanation:

x^2+5x-14

factor by finding multiples of (-14) that add up to 5

7*-2=-14

7+-2=5

So the factored out equation is (x+7)(x-2)

Therefore the solutions are x=-7 and x=2
