Answer:

47/10x

**<u>Do not leave your answer as a decimal, slope is usually in fraction form</u>**

Step-by-step explanation:

Slope Formula: \frac{\text{rise}}{\text{run}} /  \frac{y_2 - y_1}{x_2 - x_1} In this formula, subtract the 1st coordinate from the second. So, the 2nd y coordinate goes first, place a "minus" sign, and then the 2nd y-coordinate. This is the same for the x coordinates.

Finding the Answer: To find the answer, we just plug the numbers correctly into the equation, just as I explained above. We would do 55-8 first, which is 47, and then 12-2 which is 10.

Combined, the answer is 47/10x. You always place an x after the slope, which can be used to plug in other numbers. The answer cannot be simplified anymore, so this is simplfied.

MZTRI = 3x - 5, mZIRB = x + 27,<br> and mZTRB = 86. Find the mZTRI.
denis23 [38]

Answer:

m∠TRI  = 43

Step-by-step explanation:

m∠TRI +  m∠IRB = m∠TRB

3x - 5 + x + 27 = 86

3x + x - 5 + 27 = 86   {Combine like terms}

     4x  + 22    = 86       {Subtract 22 from both sides}

               4x = 86 - 22

                4x = 64           {Divide both sides by 4}

                  x = 64/4

                 x = 16

m∠TRI = 3x - 5

           = 3*16 - 5

          = 48 - 5

          = 43

Find the ratio a:c if <br>a:b = 1:2, b:d = 4:5, d:c = 3:1<br>​
Makovka662 [10]

Answer:

a : c = 6 : 5

Step-by-step explanation:

Expressing the ratios in fractional form, then

\frac{a}{c} = \frac{a}{b} × \frac{b}{d} × \frac{d}{c} = \frac{1}{2} × \frac{4}{5} × \frac{3}{1} = \frac{12}{10} = \frac{6}{5}

Thus a : c = 6 : 5
