Answer:

X= -5, Y= 16/3

Step-by-step explanation:

Okay, first line dem up:

-5x+3y=-19

-x-3y=-11

We can add, so -5x plus -x is -6x Y gets cancelled out, and -19 plus -11 is -30. So our equation is:

-6x=-30

This means that x equals -5, and now we substitute the answer in an equation to find "y". I chose equation 2. So with x factored in, it's:

5-3y=-11

Subtract both sides by 5.

-3y=-16

And we get: y= 16/3

Answer:

  0

Step-by-step explanation:

The slope is the change in y divided by the corresponding change in x:

  ∆y/∆x = (54.99 -54.99)/(7 -6) = 0/1 = 0

The slope of the line is zero.

The two lines below intersect as shown what the value of x (2x+29) (9x-13)
tensa zangetsu [6.8K]

Given:

Two lines intersect each other.

Consider the below figure attached with this question.

To find:

The value of x.

Solution:

If two lines intersect each other then the vertically opposite angles are congruent and their measures are equal.

In the given figure, the measures of two vertically opposite angles are (2x+29)° and (9x-13)°.

2x+29=9x-13

2x-9x=-29-13

-7x=-42

Divide both sides by -7.

x=\dfrac{-42}{-7}

x=6

Therefore, the value of x is 6.

Find the value of z in the figure below.<br>.​
zzz [600]

answer

z = 100

opposite angles

when inscribed in a circle, the opposite angles of a quadrilateral add up to 180

so z + 80 = 180 and y + 120 = 180

solve for z

z + 80 = 180

z = 180 - 80

z = 100
