X=2y-4 7x+5y=-66 solve by elimination
Alexxandr [17]

Answer:

{x,y}={-8,-2}

Step-by-step explanation:

 [1]    x = 2y - 4

Plug this in for variable  x  in equation [2]

  [2]    7•(2y-4) + 5y = -66

  [2]    19y = -38

Solve equation [2] for the variable  y

  [2]    19y = - 38

  [2]    y = - 2

By now we know this much :

   x = 2y-4

   y = -2

Use the  y  value to solve for  x

   x = 2(-2)-4 = -8

Use the slope formula to find the missing coordinate. m = -7/2 , T(13, 2), W(_, -5)
m_a_m_a [10]

Answer:

Option C. 15

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

T(13,2)\ W(x2,-5)

m=-\frac{7}{2}

Substitute the values  and solve for x2

-\frac{7}{2}=\frac{-5-2}{x2-13}

-\frac{7}{2}=\frac{-7}{x2-13}

equate the denominators

x2-13=2\\x2=2+13\\ x2=15

Anuta_ua [19.1K]

Answer: 225 meters per second

Step-by-step explanation:

Bruno was able to reach 450 meters in just 2 minutes.

His velocity therefore, can be determined by the speed formula which is:

= Distance / Time

= 450 / 2

= 225 meters per second

= 225 m/s

His velocity is 225 m/s.

Solve the following formula for the indicated variable.<br> – 5x – 3y = 13: solve for y.
SashulF [63]

9514 1404 393

Answer:

  y = -5/3x -13/3

Step-by-step explanation:

In any "solve for ..." problem, it is useful to start by identifying where the target is and what has been done to it. Here, y is in one term on the left side of the equation and it has had these things done to it:

  • multiply by -3
  • add -5x

We want to undo these in reverse order. We undo addition by adding the opposite. We undo multiplication by multiplying by the reciprocal (equivalently, dividing). <em>Whatever we do to one side of the equation, we must also do to the other side</em>.

So, first we add the opposite of -5x to both sides of the equation.

  -5x +5x -3y = 13 +5x

  -3y = 13 +5x . . . . . . . . . collect terms

Next, we undo the multiplication by -3. We can do that by multiplying both sides by 1/(-3) = -1/3.

  (-1/3)(-3y) = (-1/3)(13 +5x)

  y = -5/3x -13/3 . . . . . also we rearranged the terms to standard form
