Solve for x pls ASAP

Mathematics
1 answer:
choli [55]3 years ago
8 0

Answer:

x=20

Step-by-step explanation:

We know a straight line is 180 degrees so the upper corner is 60 degrees

The other corner is 55 because we see that the mirror side is the exact same

Total angle in a triangle is 180 so 60+55=45

2x+5 = 45

subtract 5 from each side to get

2x=20

x=10

Solve the system using substitution:<br> y = -6x + 7<br><br> 3x – 2y = 16<br><br> helppp
bearhunter [10]

Answer:

x=-6 y=-1

Step-by-step explanation:

// Solve equation [2] for the variable  y  

 

 [2]    y = -x - 7

// Plug this in for variable  y  in equation [1]

  [1]    3x - 2•(-x -7) = -16

  [1]    5x = -30

// Solve equation [1] for the variable  x  

  [1]    5x = - 30  

  [1]    x = - 6  

// By now we know this much :

   x = -6

   y = -x-7

// Use the  x  value to solve for  y  

   y = -(-6)-7 = -1  

Solution :

{x,y} = {-6,-1}

Shawna, Dexter, and Tilana are solving the equation -2.5(5-n)+2=15. Shawna says, “I can begin by dividing each side of the equat
laila [671]
Hi!
Shawna is correct because since it's multiplied to the  5-n you have to do the opposite which is division. 
Dexter is also correct because after distributing you can continue solving, there is nothing wrong with that. 
Hope this helps!

Morgarella [4.7K]
We have
y²=-12x

the vertex is the point (0,0)------------- > see the attached figure
<span>
standard form: (y-k)^2=4p(x-h), with (h,k) being the (x,y) coordinates of the vertex.
vertex(0,0) 
4p=-12---- > p=-12/4
p=-3
Focus:(-3,0)

</span>the answer is (-3,0)
