Answer:

x and y = (2,-1)

Step-by-step explanation:

3x + 5y = -11

3x = -1 - 7y

-(-1 - 7y) + 5y = -11

y = -1

3x=-1-7x(-1)

x = 2

(x,y) = (2,-1)

-3x2+5x(-1) = -11

3x2+7x (-1) = -1

-11 = -11

-1 = -1

solution

x and y = (2,-1)

NEED HELP ASAP!

We see it is the y terms squared so it opens left or right

in form
(y-k)^2=4(p)(x-h)
vertex is (h,k)
and p is distance from focus to vertex, also distance from vertex to directix
if p>0, then it opens to the right and dirextix is to the left of vertex
if p<0, then it opens to the left and directix is tothe right of vertex


so
(y-1)^2=4(4)(x-(-3))
vertex is (-3,1)
4>0 so dirextix is to left of vertex
left is in x direction
-3-4=-7
directix is x=-7

Darrin graphs the following inequality: y &gt; -3x -5. Does the side of the line with all solutions (the shaded region) include
Anarel [89]

Yes it does include the test point (0, 0)

  • equation:  y > -3x -5

<h3>Find y-intercept:</h3>
  • y > -3(0) -5
  • y > -5

<h3>Find x-intercept:</h3>
  • y > -3x -5

<u>switch sides</u>

  • -3x - 5 < 0
  • -3x < 5

<u>Multiply both sides by -1 reverses the inequality</u>

  • x > -5/3

Thus, the following (0, 0) comes under the following x > -5/3 and y > -5

What is the equation of the line that has a slope of -4 and passes through the point (2, 3)?
rosijanka [135]

Substituting into point-slope form,

y-3=-4(x-2)\\\\y-3=-4x+8\\\\\boxed{y=-4x+11}
