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

Put the following equation of a line into slope-intercept form, simplifying all fractions. 2x-3y=−9

Paha777 [63]

Answer:

Step-by-step explanation:

Slope-intercept from: y = mx +c

Here, m is the slope & c is the y-intercept.

So, we have to isolate y. To isolate y first subtract 2x from both sides.

2x - 3y = -9

-3y = -2x -9

Now, divide the entire equation by the co efficient of y (-3)

$\dfrac{-3}{-3}y=\dfrac{-2}{-3}x-\dfrac{9}{-3}\\\\\\y=\dfrac{2}{3}x + 3$
