Solve the following system of equations. 3x+4y=12
Lesechka [4]

Answer:

(0,3) is the solution set for given system.

Step-by-step explanation:

Given that:

3x+4y=12  ------- eq1

2x-3y= -9 ------- eq2

Multiplying eq1 with 2 and eq2 with 3 we get:

6x + 8y = 24 --------- eq1

6x - 9y = -27 -------- eq2

Subtracting eq2 from 1 we get:

17y = 51

Dividing both sides by 17 we get:

y = 3

Putting value of 3 in eq1 we get:

3x + 4(3) = 12

3x + 12 = 12

3x = 0

Dividing both sides by 3

x = 0

So the solution set will be: (0,3)

i hope it will help you.

Akayo claims that there are centers of dialstiond through ehich a dialation of line n by a factor of 1.5 leaves line n unchanged
mars1129 [50]

Answer:

See Explanation

Step-by-step explanation:

This question requires further details. In absence of the details, I will answer on a general term.

When a line is dilated (whether expanded or compressed), the new line will be on the same line with the dilated line; however, the length of both lines will be different

Take for instance:

<em>Line AB of coordinate (1,3) is horizontally dilated by 2, </em>

<em>Horizontal dilation rule is: y = f(cx) where c is the dilation factor</em>

<em />

<em>So, the new point will be </em>

<em>A'B' = (1, 3 * 2)</em>

<em>A'B' = (1,6)</em>

<em />

<em>When you compare the x coordinate of both line, you will observe that they have the same x coordinate of 1. </em>

<em>This implies that they are on the same level but different length</em>

<em />

The same is applicable to vertical dilation

<em />

<em>the new point will be:</em>

<em />
