Help stuck on question number 10
Zolol [24]

Answer:

y = 2/3x - 5  or   in standard form 3y = 2x - 5

Step-by-step explanation:

Remember this fact: Parallel lines have the same slope

Step 1   Solve for y  so that the equation is in the slope- intersect form

         2x - 3y = 6

          -3y = -2x + 6  

           -3y/-3  = -2x/-3 + 6/-3

             y = 2/3 x -2        

  now we know the slope is 2/3  or

   when the equation is in Standard form Ax + By = C   you can use this fact:  slope = - A/B    so  the slope = -2/-3 = 2/3

    Remember the   Parallel lines have the same slope

     Find the y-intersect "b"     use the slope = 2/3 and point (6, -1)

      y = mx + b

       -1 = 2/3(6) + b

       -1 = 4 + b

       -5 = b    

Now write the equation of line that is parallel to the given line and passes through  point (6, -1)

y = 2/3x - 5  or  in standard form 3y = 2x - 5

Solve the system of equations x+4y=15 2x-y=-15
Lady_Fox [76]

x+4y=15 2x-y=-15


We have to make x neg.


-2(x) + 4y (-2)= -2(15)


-2x-8y=-30

2x-y=-15


-9y= -45


Solve for y


Y=-45/-9


Y = 5

Substitute your y answer into one original equation to find x .


x+4y=15


X+4(5)=15


X+20=15


X=15-20


X= -5


Answer is (-5,5)

How do you solve 16 = 17 - t
Ivanshal [37]

So I looked it up on another math helper app called ( Socratic )and this is what popped up on my screen Simplifying

16 = 17 + -1t

Solving

16 = 17 + -1t

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add 't' to each side of the equation.

16 + t = 17 + -1t + t

Combine like terms: -1t + t = 0

16 + t = 17 + 0

16 + t = 17

Add '-16' to each side of the equation.

16 + -16 + t = 17 + -16

Combine like terms: 16 + -16 = 0

0 + t = 17 + -16

t = 17 + -16

Combine like terms: 17 + -16 = 1

t = 1

Simplifying

t = 1

So I’m pretty sure that’s the answer:) if not I’m truly sorry.
