Answer:

x = 14, y = 37

Step-by-step explanation:

The angle vertically opposite (4y-10) is also a corresponding angle to (9x + 12) so that means that angles (4y-10) and (9x+12) are equal.

4y-10 = 9x+12 -----Equation 1

You also know that (4y-10) and 3x add up to 180° since they both lie on a straight line.

4y-10+3x = 180 -----Equation 2

From the above equation, I'm going to isolate (4y-10) so that I know a value that I can substitute in Equation 1.

4y-10 = 180-3x -----Equation 3

Substitute 4y-10 = 180-3x into Equation 1.

4y-10 = 9x+12

180-3x = 9x+12

Put the like terms together.

180-12 = 9x+3x

Evaluate.

12x = 168

Find x.

x = 168 ÷ 12

x = 14

Subsitite x = 14 into Equation 3.

4y-10 = 180-3x

         = 180-3(14)

         = 180-42

         = 138

Isolate 4y.

4y = 138+10

    = 148

Find y.

y = 148 ÷ 4

y = 37

Answer:

Step-by-step explanation:

3x + 9x +12 = 180 {linear pairr}

    12x + 12 =180

        12x = 180 - 12  

         12x = 168

             x = 168/12

x = 14

3x  = 3*14 = 42

4y - 10  + 3x = 180         {linear pair}

4y - 10 + 42 = 180

         4y + 32 =180

              4y  = 180 - 32

              4y = 148

                y = 148/4

               y = 37

Try to find x & y. I need it so much please
kumpel [21]

Answer:

x = 3

y = 5

Step-by-step explanation:

Using theorem of similar triangles, we have,

(6 + x)/6 = (7 + 3.5)/7

(6 + x)/6 = 10.5/7

Cross multiply

7(6 + x) = 10.5(6)

42 + 7x = 63

7x = 63 - 42

7x = 21

x = 21/7

x = 3

Thus:

7.5/y = (7 + 3.5)/7

7.5/y = 10.5/7

Cross multiply

7.5*7 = 10.5*y

52.5 = 10.5*y

Divide both sides by 10.5

52.5/10.5 = y

y = 5

First of all, your fractions that you wrote were wrong. You flipped the numbers over. When you're finding the slope of a graph, the number on the y-axis is always the numerator while the x-axis is the denominator. 

Your first answer would be the actual slope- which is 3.

Your second answer would be the number of products that company would sell if the got 1,000 web views So just multiply 3 by 1,000. That means that the company will sell 3,000 products.
