Mathematics

Answer:

2/3

Step-by-step explanation:

First find the slope of the line

3x+2y = 7

Subtract 3x

2y = -3x+7

Divide by 2

y = -3/2x +7/2

This is in slope intercept form  y = mx+b  where m is the slope

The slope is -3/2

A line perpendicular is the negative reciprocal

-1/(-3/2)

2/3

The slope of the perpendicular line is 2/3

Answer:

Slope of the line perpendicular to the given line = 2/3

Step-by-step explanation:

The product of the slopes of lines perpendicular to each other is - 1

That is,

      slope_{1} \times slope _ 2 = - 1\\

Given equation of the line :

                                  3x + 2y = 7

                                          2y = - 3x + 7

                                          y = -\frac{3}{2}x + \frac{7}{2}

Therefore, \ slope \ of  \ the \ given \ line \ , slope _1 =  \ -\frac{3}{2}

<em><u>Find slope of the line perpendicular to the given line:</u></em>

<em><u /></em>\frac{-3}{2} \times slope_2 = - 1\\\\slope_2 = - 1 \times \frac{2}{-3} = \frac{2}{3}<em><u /></em>

-t+5=t-19<br> Need an answer and a work pls!
Nadusha1986 [10]

Answer:

t=12

Step-by-step explanation:

Step 1: Subtract t from both sides.

−t+5−t=t−19−t

−2t+5=−19

Step 2: Subtract 5 from both sides.

−2t+5−5=−19−5

−2t=−24

Step 3: Divide both sides by -2.

−2t−2=−24−2
