Line l is perpendicular to line m with equation 2x + 5y = 20. line l intersects line m at (-5,6).
VladimirAG [237]

Answer:

The equation is y = -2/5x + 4

Step-by-step explanation:

First we have to find the slope of the line. In order to do so, solve the first equation for y.

2x + 5y = 20

5y = -2x + 20

y = -2/5x + 4

This gives us a slope of -2/5. Given that information, we now can plug the slope and point into point-slope form and get the final equation.

y - y1 = m(x - x1)

y - 6 = -2/5(x - -5)

y - 6 = -2/5(x + 5)

y - 6 = -2/5x - 2

y = -2/5x + 4

4. Is the point (3,-4) a solution to the given system? Justify your answer.
Zigmanuir [339]

Answer: No, it is not a solution

==========================================================

Explanation:

The point (3,-4) means that x = 3 and y = -4 pair up together

Let's plug these x,y values into each equation

Starting with the first equation, we get,

y = 4x-16

-4 = 4(3)-16 ... x replaced with 3; y replaced with -4

-4 = 12-16

-4 = -4 .... this is a true statement

Repeat for the second equation

y = 2x-6

-4 = 2(3)-6

-4 = 6-6

-4 = 0 ... this is false

Since we get a false statement, this means (3,-4) is not on the line y = 2x-6, which means that overall (3,-4) is not a solution to the system of equations. The point (3,-4) must make both equations true for it to be a solution.

PLEASE HELP<br> A) 8<br> C) 1<br> B) 6<br> D) 7<br><br> What is the value of x?
SVEN [57.7K]

Answer: 7

Step-by-step explanation:

As tangents drawn from a common external point to a circle are congruent,

  • 8x - 7 = 6x + 7
  • 2x - 7 = 7 [subtract 2x from both sides]
  • 2x = 14 [add 7 to both sides]
  • x = 7 [divide both sides by 2]
