Answer:

x = 11 , z = 116

Step-by-step explanation:

(9x - 15) and (5x + 9) are vertically opposite angles and are congruent, then

9x - 35 = 5x + 9 ( subtract 5x from both sides )

4x - 35 = 9 ( add 35 to both sides )

4x = 44 ( divide both sides by 4 )

x = 11

Then

5x + 9 = 5(11) + 9 = 55 + 9 = 64

z and 5x + 9 are adjacent angles on a straight line and sum to 180°, that is

z + 64 = 180 ( subtract 64 from both sides )

z = 116

Answer:

Depending depending whether your work is in relation to euclidean geometry. You can use the properties of straight lines in order to get your answer.

Step-by-step explanation:

  1. I'm going to presume that you used vertically opposite angles to get the value of x?
  2. So the answer for x = 11 so
  3. 3(11)+9 = 64 and 9(11)-35 = 64 [reason vertically opposite angles are equal]
  • So using angels around a point - angles around a point are equal to 360°
  • 360 - [64 + 64] = 232
  • 232 ÷ 2 = 116 so z = 116.

If graphed in the plane, would the line y=5x-2 pass through the point (4,15)
yulyashka [42]

Answer:

no

Step-by-step explanation:

Using substitution, subs in the points given

(15) = 5(4) - 2

15 = 20 - 2

Because the 2 sides are NOT equal the line would not pass through the point

The variable Z is directly proportional to X. When X is 5, Z has the value 55.
LuckyWell [14K]
Z = k * x
55 = k * 5
divide both sides by 5
11 = x

z = 11x

z = 11 * 12
z = 132

PLEASE I NEED HELP QUICKLY!!! Find the solution for the given system of equations in the form (x,y).
goblinko [34]

Answer:

  • (4, - 4)

Step-by-step explanation:

<u>Given system:</u>

  • -x + y = 8
  • 7x + 3y = - 16

<u>Multiply the first equation by 7 and add up the equations:</u>

  • -7x + 7y + 7x + 3y = 7*8 - 16
  • 10y = 40
  • y = 4

<u>Find y:</u>

  • -x + 4 = 8
  • -x = 4
  • x = - 4
