Licemer1 [7]
the correct answer for this problem: x= -1/3y + 2

Let’s solve for x
3x + y= 6

Add -y to both sides
3x + y + -y = 6+ -y
3x = -y + 6

Divide both sides by 3
3x/3 = -y + 6/ 3

And so your answer is at the top hope this helps.

Answer:

  • 55°, 70°, 55°

Step-by-step explanation:

<u>Δ MHP is right triangle, therefore</u>

  • m∠P = 90° - 35° = 55°

<u>ΔMNP  is isosceles triangle as MN = MP, therefore</u>

  • m∠N = m∠P = 55°
  • m∠NMP = 180° - 2*55° = 70°

Answer:

E' = (-4, 3)  Answer C in your list of options

See attached image for the plot.

Step-by-step explanation:

Recall that a rotation in 180 degrees around the origin produces the following change in coordinates: (x, y) --> (-x, -y)

Therefore, since we read the coordinates of point E as: (-4, 3),

the new coordinates after the rotation will be: (4, -3) and the point will look like the red point in the attached image.

Find the equation of the line passing through the point (6,3) that is perpendicular to the line 4x−5y=−10.
Paul [167]

Step-by-step explanation:

( y = 4x/5 + 2)

m1.m2 = -1

4/5.m2 = -1

m2 = -5/4

formula = y - y1 = m2 ( x - x1)

y - 3 = -5/4 ( x - 6)

y -3 = -5x /4 + 30/4

y = -5x /4 + 21/2
